ABSTRACT:
A process for recovering monomeric glycols and glycerine from polyoxyalkylene glycols and polyglycerines which comprises heating the polymeric compounds together with a lower saturated mono-carboxylic acid, containing from 2 to 4 carbon atoms such as acetic acid, in the presence of a strong acid, e.g. sulfuric acid, or a strong acid cation exchange resin. The product, which is the diester of the monomeric glycol or the triester of glycerine, is recovered and subsequently hydrolyzed to obtain the desired monoglycol or glycerine product. If it is desired to obtain the ester itself, the latter step of hydrolyzing can be omitted.
