The crystals are then isolated by any suitable technique such as by filtration. Thus, the disadvantages of providing diacetone glucose via the known procedures are likewise present in making the monoacetone derivative through the diacetone intermediate. Particularly covers a process of making diacetone glucose under carefully controlled conditions via an acid-catalyzed reaction. PREPARATION OF DIACETONE GLUCOSE In the instant invention diacetone glucose, that is, 1,2;5 ,6-Di-O-isopropylidene-a-p-glucofuranose, is prepared by reacting glucose with acetone under the specific conditions set out hereinafter. Nos. The invention is hereby claimed as follows: 1. Also covers a procedure for making monoacetone glucose from diacetone glucose through ion exchange techniques. This ammonium sulfate salt is then conveniently removed from the product dissolved in acetone by a convention step such as by a filtration technique. Any suitable resin containing weakly acidic acid groups capable of exchanging cations is useful. . So, acetone does dissolve certain inorganic salts, but probably only the more covalent ones, such as CuCl2. These bonds will keep acetone dissolved completely in water, resulting in … Other than by treatment with resin, the diacetone glucose product solution may also be purified in a number of other ways. 27, 1973 8/1955 Glen et a.l. spontaneous combustion - how does it work? Thus, the process is admirably suited to operation in a continuous manner, particularly when run under reflux conditions. As is readily apparent, the purification technique just described is relatively inexpensive and simple to carry out, and particularly eliminates relatively costly toxic or explosive reagents such as petroleum ethers or like organic solvents, often used in purification procedures. Ammonia was bubbled into the diacetone glucose filtrate until a pH of 7.0 was maintained. This product is removed from the reaction vessel periodically or continuously bled off as a solution in acetone, while additional dry acetone is metered in, as well as glucose when needed. Most preferably 50-75 percent of the acetone is removed. In like manner, monoacetone glucose production on a commercial scale has also been hindered, since no simple procedure is known for its production without it being connected with a first formation of diacetone glucose. Metals are OK but acetone will remove any grease, oil or pant on them.

A process for preparing monoacetone glucose that consists of: passing through a column of a weak acid cation exchange resin having carboxylic or phenolic groups containing exchangeable cations and that is in the hydrogen form a solution of diacetone glucose that contains from 5 to 10 percent of diacetone glucose on a dry solids basis, at a temperature in the range from 78* C to 82* C; and recovering monoacetone glucose from the column, substantially free of diacetone glucose and of glucose. Examples of suitable tertiary amines are trimethylamine, triethylamine, tributylamine, dimethylpropanolamine, dimethylamine, methylamine, dioctyl ethanolamine, and homologues thereof. 2,614,099. Another preferred embodiment to form monoacetone glucose involves passing diacetone glucose solution through a resin column at a rate sufficient to insure reaction. Acetone, or propanone, is an organic compound with the formula (CH 3) 2 CO. ... (HBA) bases exhibiting moderate to high dielectric constants are able to dissolve glucose (in general sugars). water is polar acetone is nonpolar. I understand that the carbonyl group in acetone is polar and therefore accounts for its solubility with water and aqueous solutions ("like dissolves like"); but how does it account for being able to dissolve organics? Water at 60 C was then metered into the product solution while stripping off the remaining acetone until the solids content of diacetone glucose in solution was about sixeseven percent. However, the invention is particularly suited toward purification of product as follows whether obtained from a batch-wise or continuous method. No. Still another object of the invention is to provide a process of preparing diacetone glucose in a continuous manner, which process is particularly suitable to use in an industrial installation. In this reaction, acetone is the solute and water is the solvent. 4. The diacetone glucose is concentrated to about a 5-l0 percent solids content at this point, which amount is soluble in the hot water solution. 2. Adding potassium iodide to form negatively charged iodide can increase its solubility because of the hydrogen bonds present in water, which can dissolve ions. However, as the reaction proceeds the diacetone glucose product is soluble in the acetone phase, and can be easily recovered from excess acetone acting then as a solvating agent. It is especially the case for ethanol, methanol, propyleneglycol, glycerol, acetone and pyridine. Acetone is an irritant to nose, throat, lungs, and eyes with high exposure causing headaches and dizziness [8]. The copolymer is normally made up of 0.5 to percent by weight of polyvinyl material, and preferably 0.5 to 20 percent by weight. Examples of such amines are methylaniline, dimethylamine, N-butylamine, dibutylamine, isobutylamine, aniline. 615,307, filed Feb. 13, 1967, now U. S. Pat. Get your answers by asking now. For example, resin contact may be made with a solution of diacetone glucose such as an aqueous solution after stripping off excess acetone. Favorite Answer. No. Many kinds of plastic do not dissolve in acetone. Therefore, based on the principle that “like dissolve … In the particular acetone solvent system involved, upon cooling the ammonium sulfate salt formed via the neutralization step is precipitated out almost quantitatively from solution, leaving behind little salt contaminant. 7 years ago. Examples of weakly basic anionic exchange resins which can be employed are those described in U.S. Pat. Any mineral acid may be employed such as sulfuric, hydrochloric, phosphoric, nitric, etc. The mother liquor from the filtration step may also be worked-up to recover additional diacetone glucose and increase over-all yield. In this step the diacetone glucose dissolved in solvent, and preferably dissolved in water at about a l0 percent solids content is contacted with an anion exchange resin. anion exchange resins are also prepared by halogenating the resin molecule and then introducing an anionic exchange group. One particular technique involves concentrating a 5-10 percent aqueous solution of diacetone glucose product to about 10-20 percent solids, treating the hot solution with activated carbon, filtering the carbon from the product solution and cooling to obtain the crystalline product. The diacetone glucose hydrolyzed in this step is preferably dissolved in hot water, and the resin contact thereafter made within the above temperature range. Acetone’s chemical makeup includes elements that are both polar and nonpolar which means acetone … Glucose is polar. On the other hand, CuSO4.5H2O and CuSO4 do not dissolve at all. Thanks CoCl2 also dissolves, it gives a blue solution. In addition, covers a continuous method of synthesizing diacetone glucose, and as well is concerned with synthesizing monoacetone glucose from glucose by proceeding through the intermediate diacetone glucose without isolation of the diacetone derivative. Like dissolves like. Likewise, the product may be maintained in solution form, and utilized as such. In addition, even if a simplified and economically attractive method of making diacetone glucose were known, no commercially acceptable procedure is set forth in the literature for preparing the monoacetone glucose derivative from the diacetone glucose material. Or how would I explain the result? of moisture present. One excellent method is to spray-dry the mother liquor and recover therefrom the desired product. [52] U.S. Cl ..260/210 R, 260/2.5, 260/9 [51] Int. 3. As alluded to above, the instant reaction is acid-catalyzed. View chapter Purchase book. Again, if other resin systems were employed and even a strong acid cationic exchanger, the process was essentially non-controllable. 0 … Examples of strongly basic anionic exchange resins which can be employed in the practice of the invention are those described in U.S. Pat. Particularly covers a process of making diacetone glucose under carefully controlled conditions via an acid-catalyzed reaction. Like dissolves like. Polar organics like acetone or isopropanol or ethanol (or vodka) will dissolve it because you get hydrogen bonding that hold the molecules in solution. 2,591,573; 2,597,440; 2,597,494; 2,614,099; 2,630,427; 2,632,001 and 2,632,000. Acetone is highly volatile, completely miscible with water, has weak soil sorption (log K oc =0.73), does not bioaccumulate in aquatic organisms (log K ow =−0.24), and is not likely to biomagnify. Yes. The remainder of the acetone, of course, is removed during the subsequent addition of hot water. This step may be run whether the processor is working the reaction in a continuous manner or in batches. Specifically, a weak acid cationic exchange resin, AMBER- LITE lRC-SO in hydrogen form was preheated to about 80 C and added to this heated diacetone glucose aqueous liquor. But I got it wrong. No. Generally, use of an additional solvent is undesirable, since both yield and reactivity are diminished due to excessive solvating debilitation of catalyst. Broadly speaking, diacetone glucose is prepared by reacting substantially dry acetone with glucose in relatively low molar ratios of acetone to glucose in presence of a mineral acid catalyst at a specific temperature ranging from about 45 C to about C, and for a duration of time varying from about Vi hour to about 10 hours. When an aqueous solution of diacetone glucose is treated with carbon to remove impurities therefrom, it. Answer Save. The mineral acid should be concentrated, and free of substantial amounts of water. * I had written that water is polar and so is glucose, while hexane is non polar. Answer: the molecule of acetone ( CH₃-CO-CH₃)Explanation:1) the Acetone is CH₃-CO-CH₃2) Which is a molecule (accumulation of covalent bonds).3) When it dissolves, covalent bonded compounds remain as separate molecules, then it is said that the main species present in the solution is the molecule. A process for preparing monoacetone glucose consisting of: contacting an aqueous solution that contains from 5 percent to 10 percent of diacetone glucose on a dry solids basis with a weak acid cation exchange resin having carboxylic or phenolic groups containing exchangeable cations and that is in the hydrogen form, at a temperature in the range from C to 90 C, and. However, most preferred is sulfuric acid due to availability, low cost, excellent activity, and easy removability in the subsequent purification procedure. It is understood, of course, that these examples are merely illustrative, and that the invention is not to be limited thereto. Well, the tittle says it all. A process for preparing monoacetone glucose that consists of: contacting a solution of diacetone glucose that contains from 5 to 10 percent diacetone glucose on a dry solids basis with a weak acid cation exchange resin having carboxylic or phenolic groups containing exchangeable cations and that is in the hydrogen form, at a temperature in the range from 78 C to 82 C, by adding beads of the resin to the solution to form a slurry; agitating the slurry for a period of time from 1/10 of an hour to 3 hours; and. To do this: 1) Empty a cup or two of epsom salts on to cookie sheet or baking dish or whatnot and stick in the oven on 350F for about 3 hours. 4. Hydrolysis was then effected at about 80 C. During the contact period the resin slurry was stirred. Generally, the reaction is allowed to proceed after start-up until excess acetone present contains dissolved therein a substantial amount of the desired diacetone glucose product. A suitable anion exchange resin of the type described above is available as AMBERLITE lRA-40l-S, preferably employed in the hydroxide form. In all instances the proposed methods have one or more drawbacks which make them unacceptable for commercial adaptation. A process for preparing monoacetone glucose consisting of: forming diacetone glucose by reacting together sub- I stantially dry acetone and glucose in relative proportions of at least about 4 moles but less than 10 moles of acetone per mole of glucose in the presence of a catalytic amount of a mineral acid, at a temperature in the range from about 45 C to about 80 C for from about A of an hour to about 10 hours; recovering unreacted excess acetone and diacetone glucose from the reaction mixture; preparing diacetone glucose by reacting together substantially dry acetone and glucose in relative proportions of at least about 4 moles but less than moles of acetone per mole of glucose in the presence of a catalytic amount of a sulfuric acid catalyst, at about the reflux temperature of acetone, for a period of time in the range from about A of an hour to about 5 hours; neutralizing the resultant reaction mixture with ammonia, whereby ammonium sulfate salt is formed that precipitates from the reaction mixture; removing the precipitate from the reaction mixture; stripping off excess acetone while simultaneously adding water to form an aqueous solution of diacetone glucose containing 5 to 10 percent of diacetone glucose on a dry solids basis; contacting the aqueous solution of diacetone glucose with a weak acid cation exchange resin having carboxylic or phenolic groups containing exchangea- I ble cations and that is in the hydrogen form, at a temperature in the range from C to C, to form monoacetone glucose; and. As a fatty acid, stearic acid is a relatively non-polar compound. Explain the difference between saturated and unsaturated fats. This favorably compares to prior art procedures set out in the literature which require a minimum of moles per mole of glucose, and in most instances require in the neighborhood of -25 moles of acetone per mole of glucose reactant. The weak base resins are prepared in a similar manner except that primary and secondary amines are reacted with the halo alkylated resins. When a portion of the acetone is removed by stripping from the diacetone glucose product prior to addition of any water, it is preferred that at least 50 percent of the acetone be removed prior to water addition. It therefore becomes an object of the invention to provide a method of preparing diacetone glucose. 7. Join Yahoo Answers and get 100 points today. Polypropylene and nylon are unaffected, PTFE unsurprisingly handles it just fine as well. The majority of these materials are resinous beads having carboxyl or phenolic groups containing exchangeable cations. This mode of synthesis is particularly adapted to a continuous manner of making diacetone glucose on a commercial scale. A special object of the invention is to provide a method of making monoacetone glucose by first preparing the diacetone glucose intermediate from a special reaction of glucose with acetone, and subsequently preparing the monoacetone material without first isolating the diacetone parent. For excellent yields it is again greatly preferred that the aqueous solution of the diacetone glucose contain 5-10 percent solids, the cationic exchanger be in hydrogen form, and the temperature of reaction narrowly range between 78 and 82 C. If these conditions are followed, yields of monoacetone glucose as high as 95 percent or higher may be obtained with little difficulty. In many instances, hydrolysis of the diacetone glucose to the monoacetone material is accompanied by severe decomposition, and other serious side-effects in the proposed processes. A molecule of sucrose has eight hydroxyl groups, three hydrophilic oxygen atoms (bound in a circle) and 14 hydrogen atoms. Still have questions? Specifically something that would evaporate and leave behind the sugar as a residue. Big Bird Y. Acetone | CH3COCH3 or CH3-CO-CH3 or C3H6O | CID 180 - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. In its broadest outline the method is carried out by contacting a source of diacetone glucose in some solvent with a weak acid cationic exchanger under a critical temperature range of 75-90C. The wet crystalline cake from the above filtration step may be dried in a vacuum oven, say at about 140 F, and the diacetone product obtained as a white solid having a melting point of l07l09 C. The most preferred carbon material useful in removing impurities is activated carbon. It appears that the unique system described above of specific combination of particular resin and temperature range is essential in order to realize yields of the magnitude envisioned with respect to monoacetone glucose production. Most chemical bottles are glass, HDPE, or FET/PTFE and should be fine, although cap liners are sometimes polystyrene. The strongly basic anion exchange resins which are preferably employed for the purpose of the invention are reaction products of a tertiary amine and a vinyl aromatic resin having halo methyl groups attached to the aromatic nuclei in the resin. A still further object of the invention is to provide a method of making monoacetone glucose from the diacetone derivative in a one-step procedure requiring minimal product purification, which method results in excellent yields of the monoacetone material. We have also discovered a procedure for synthesizing the monoacetone glucose derivative from the diacetone material. After a reaction time of about 0.5 hour the resin was removed by rapid filtration and the resultant monoacetone glucose liquor concentrated up to about 60 percent solids. As set out above the temperature of reaction may range from about 45 C to about 80 C, more often is 5060 C and may be effected at either atmospheric or elevated pressures, say as high as I00 p.s.i.g. The hot aqueous diacetone glucose was then passed over a strong base anionic exchange resin, namely, AMBERLlTE-IRAAOl-S in hydroxide form to remove impurities such as residual ammonium sulfate condensation products and reducing sugars. compounds that contain oxygen will repel compounds that don't. If ice is less dense than liquid water, shouldn’t it behave as a gas? A typical weak acid cationic exchanger which may be employed is AMBERLITE IRC-SO in hydrogen form. Explain why water is called a polar covalent molecule? I thought sucrose would be soluble in acetone because both substances are polar. As can be seen from Table 1 below only after about a temperature of 75 C does one achieve good yields of monoacetone glucose and absence of substantial amounts of unreacted diacetone glucose at the completion of the reaction runs. The contact time of the solution may vary somewhat but typically again ranges from about l/l to about 3 hours. This may be accomplished by starting with diacetone glucose itself, or else may be carried out in a single procedure beginning with acetone and glucose reactants, without resort to isolating the intermediate diacetone material. The solubility of d-glucose in water as a function of temperature in a mixture of ethanol/water containing (50, 60, 70, and 80) % ethanol was evaluated on the basis of the refraction index at 60 °C. Unhydrolyzed Hydrolysis Catalyzed with (Dextrose Diacetone Temp. In this case there is no necessity to isolate the diacetone glucose product, and the liquid form of diacetone glucose material may be directly utilized. In the lab sucrose looked poorly soluble in acetone solution but the teacher said it should be insoluble. Cu (NO3)2.3H2O also dissolves in acetone quite well, with a blue color. TABLE 1 Hydrolysis D.E. Covers a method of preparing acetone glucose. A process for preparing monoacetone glucose consisting of: forming diacetone glucose by reacting together substantially dry acetone and glucose in relative proportions of at least about 4 moles but less than 10 moles of acetone per mole of glucose in the presence of a catalytic amount of a mineral acid, at a temperature in the range from about 45* C to about 80* C for from about 1/4 of an hour to about 10 hours; recovering unreacted excess acetone and diacetone glucose from the reaction mixture; removing the excess acetone from the diacetone glucose; forming a solution of the diacetone glucose that contains from 5 to 10 percent by weight of diacetone glucose on a dry solids basis; contacting said solution with a weak acid cation exchange resin having carboxylic or phenolic groups containing exchangeable cations and that is in the hydrogen form, at a temperature in the range from 75* C to 90* C, to form monoacetone glucose, and recovering the monoacetone glucose substantially free of diacetone glucose and of glucose. 2,582,098; 2,597,439, and 2,597,491. PREPARATION OF MONOACETONE GLUCOSE Also falling within the ambit of the invention is the production of monoacetone glucose in a process which may be accomplished with ease and facility, yet is relatively simple, and finally produces excellent yields of product. The presence and the importance of acetone and its metabolism in diabetic ketoacidosis has largely been ignored. Excellent yields are realized if these directions are carefully followed. Crystalline sugar consists of a matrix of molecules held together by relatively weak bonds, and when submerged in water, the stronger charge of the water molecules pulls the sugar apart. methanol, acetone, ethanol and ethyl acetate. The contact of product solution with resin may be effected in a variety of ways, but most preferably is carried out by either the slurry or column techniques. When sulfuric acid is used as the mineral acid catalyst, we have found that a particularly desirable neutralizing agent is ammonia.

The mixture was then cooled to 20 C and unreacted glucose filtered and reused in the next cycle. This form, of course, is fixed, that is, there is no mutarotation. Also something that is reasonably safe to handle. ... A solute will dissolve in a solvent if the solute-solvent forces of attraction are great enough to overcome the solute-solute and solvent-solvent forces of attraction. I've switched to PLA for now (since that seemed easier to work with for now - though I'm less convinced than I was). Only a few of the impurities do not affect sucrose solubility or decrease it. Polar and ionic solutes dissolve in polar solvents: (water, acetone,methanol,ethanol) Nonpolar solutes dissolve in the nonpolar solvents: (hexane, toluene, carbon tetrachloride) 23 0 Isolation operations of exchanging cations is useful aforementioned method of producing diacetone glucose which may explained!
