Abstract
Process for obtaining esters of dicarboxylic acids, characterized by heating a mixture of a molar proportion of a cyclic anhydride of a dicarboxylic acid, with between 1 and 1.12 molar proportions, approximately, of an aliphatic or cycloaliphatic alcohol, in the presence of acid phosphoric as catalyst, under conditions and for a period such that at least about 80% of the charged dicarboxylic acid anhydride is converted to the corresponding alkyl, or cycloalkyl, half ester.
