| titleOfInvention | Method for preparing highly pure glyceryl monoester |
| abstract | Provided is a method for preparing high purity glycerin monoesters without expensive equipment.n n n Heating and refluxing at atmospheric pressure in the presence of a catalyst of glycerol, acetone and concentrated sulfuric acid or para-toluene sulfonic acid to produce glycerol protected with two alcohol groups and distilling the protected isopropylidene glycerol at atmospheric pressure, or from 10 to 750 mmHg,n n n Lower alkyl fatty acid ester was added to isopropylidene glycerol, and an alternative of Na 2 CO 3 , K 2 CO 3 , and ZnO was reacted at 100 ° C. to 200 ° C., and the isopropylidene glycol was distilled at atmospheric pressure or 10 to 750 mmHg. Removing, remaining isopropylidene glyceryl stearate is separated, cooled, and crushed to remove Na 2 CO 3 with water to prepare a protected isopropylidene glycerin stearate,n n n High-purity glycerin consisting of adding isopropylidene glyceryl stearate to the protected isopropylidene glyceryl stearate by adding ethanol or methanol or water: ethanol or methanol in a ratio of 1: 1 to 7 and a hydrophobic polyaromatic resin and reacting at atmospheric pressure. It is a manufacturing method of a monoester.n n n The production process of the high purity monoester of the present invention is represented by the chemical structural formula as follows. |
