Abstract

A process for the preparation of diallyl esters of carbocyclic aromatic dicarboxylic acids comprises catalytically transesterifying a dimethyl and/or diethyl ester of the acid with at least equivalent amount of allyl alcohol calculated with reference to the methyl or ethyl ester groups in an inert atmosphere by the gradual addition of allyl alcohol at a temperature above its boiling point, with evolution and removal of the methanol or ethanol, so that a diallyl ester is formed. Aromatic dicarboxylic acids specified include isomeric phthalic acids, diphenyl dicarboxylic and naphthalene dicarboxylic acids 5-chloroisophthalic acid, methyl terephthalic acid and dichloroterephthalic acid. Transesterification catalysts specified include magnesium methoxide, metallic magnesium butyl titanate or mixtures thereof. Examples are furnished.
