ONE BILLIONHERTZ MICROWAVE ATHERMAL ACTION ON THE SYNTHESIS OF AROMATIC ESTERS AT NORMAL PRESSURE

Abstract

Benzoic acid or p-hydroxybenzoic acid undergoes rapid reaction with alcohol using H2SO4 as catalyst at normal pressure, under irradiating continuously of the 1 GHz and 50 mW microwave for 22–60 minutes to afford aromatic esters in 76–90%yields.
