摘要
Isoamyl salicylate was synthesized by using germanotungtic acid as catalyst.The effects of the amaunt of catalyst,the molar ratio of salicycic acid of isoamyl alcohol,the reaction temperature and the reaction time on the yield of ester were studied.The optimum reaction conditions were 1.3∶100 (mass ratio) of catalyst to reactants,1∶2.5 (molar ratio) of acid to alcohol,135～153℃ being satisfactary reaction temperature and reaction time suitable being 3h.Under such condition,the yield of ester was up to 94%.Germanotungtic acid catalyst can be used repeatedly.
