| titleOfInvention | Production of polyglycerol |
| abstract | PURPOSE: To produce a polyglycerol having light color in an easily purifiable state, by adding glycidol of a molar number corresponding to the polymerization degree of the objective compound to a carboxylic acid such as formic acid, acetic acid, etc., and hydrolyuzing and decarboxylating the addition product. n CONSTITUTION: Glycidol of a molar number corresponding to the polymerization degree of the polyglycerol to be produced is added to a carboxylic acid of formula RCOOH (R is H or 1W5C alkyl) (e.g. formic acid, acetic acid, propionic acid, butyric acid, isobutyric acid, valeric acid, caproic acid, etc.), and the obtained polyglycerol carboxylate is hydrolyzed with water and then decarboxylated to obtain a polyglycerol. The product can be purified easily by neutralizing the residual carboxylic acid completely with an alkali, dehydrating and precipitating the product, adsorbing the precipitate to diatomaceous earth, etc., and filtering the adsorbed product. n USE: Emulsifier for food, humectant for cosmetic, and raw material of plasticizer, surfactant, etc. n COPYRIGHT: (C)1986,JPO&Japio |
