The easily available Montmorillonite K10 clay is activated with orthophosphoric acid. It has been found that the surface of the clay become more acidic after treating with the orthophosphoric acid. This has been used for esterification of substituted benzoic acids with different alcohols. Benzoic acids having both electron donating and withdrawing groups undergo smooth reaction and provide higher yields with methanol and benzyl alcohol. No solvent and mineral acids have been used in this reported protocol.
