Abstract

Aromatic mono or polycarboxylic acid glycidyl esters are obtained in good yields and high purity by transesterification of the corresponding aromatic carboxylic acid alkyl esters with glycidol in the presence of weakly toxic catalysts, namely the alkali, ammonium, and alkaline earth metal salts of pseudohalogen hydride acids with readily polarizable anions.
