Abstract
A process for producing esters of citric acid from citric acid and linear or branched aliphatic monoalcohols of 4 to 14 carbon atoms wherein the essential characteristics are the use of a limited stoichiometric excess amount of alcohol relative to the acid employed and the immediate acylation of the unprocessed ester, i.e. the conversion of the unprocessed ester with an acylating agent for masking the OH-- group without having previously subjected it to any purification operation.
