Abstract

Silica chloride has been found to be an efficient catalyst for esterification of carboxylic acids (aliphatic, aromatic and conjugated) with alcohols (primary, secondary and tertiary) as well as for transesterification of esters (by both alcoholysis and acidolysis).

Key words

esterification - transesterfication - silica chloride - alcoholysis - acidolysis
