Potassium carbonate solubility in glycerol

images potassium carbonate solubility in glycerol

As previously stated, besides solubility of reactants, a solvent is also utilized to transport heat. Glycerol, which is a non-toxic, biodegradable, and recyclable liquid manufactured from renewable sources, shows similar properties as an ionic liquid and has a high potential to serve as green solvent for organic syntheses. Microwave heating is based on the ability of a solvent to absorb microwave energy and convert it into heat. However, their polarity makes them immiscible in a variety of hydrophobic solvents and thus allows products separation by simple extraction. The reaction product which remained after distillation of the by-products and which consisted essentially of unreacted glycerin 8 molsglycerin carbonate and a molar excess of ethylene carbonate 40 mols total; 23 mols fresh charge was treated with 0. These results were quite unexpected since alkaline conditions have previously been known to cause the decomposition of organic carbonates, including glycerin carbonate. The experimental data accumulated so far in a wide scope of organic syntheses in glycerol proves our assumption that glycerol can perform many of the same functions as organic petroleum-based solvents and ionic liquids, as shown in Table 2.

Thus, tests have shown that the yield of glycerin carbonate under alkaline conditions As a chemi- I atented Dec. Here, we show that glycerol, which is a non-toxic, biodegradable, and recyclable liquid manufactured from renewable sources, has a high potential to serve as alternative green solvent for organic reactions.

    Asymmetric catalysis is a powerful tool in the synthesis of fine and special chemicals. In microwave heating, the solvent selection is even more crucial.

    The acidified mixture was then distilled under reduced pressure to remove the by-products of the reaction.

    A process according to claim 1, wherein the said alkaline compound is selected from the group consisting of the alkali metal hydroxides, carbonates, bicarbonates, phosphates and borates.

    Lipase-catalyzed kinetic resolution of ester racemate is an example for such successful biocatalytic reaction. The preferred materials are those acids which are substantially non-volatile during distillation of the by-product materials and which are capable of maintaining a weakly acidic condition.

    Glycerin carbonate is perhaps most valuable because of its ability to form glycidol on decomposition under controlled conditions. It involves the enantioselective transesterification alcoholysis of only one of the esters using an excess of alcohol as the resolving agent. Introduction Solvents are used daily in numerous industrial processes as reaction medium, in separation procedures, and as diluters.

    Hence, glycerol is a very attractive solvent due to its high polarity and high boiling point.

    Distillation of products is also feasible due to the high boiling point of glycerol. However, their polarity makes them immiscible in a variety of hydrophobic solvents and thus allows products separation by simple extraction. Ethanol and diethyl carbonate were stripped from the reaction mixture to a pot temperature of C.
