Catalytic Synthesis of Propyl Benzoate with NaHSO_4·H_2O

Synthesis of propy1 benzoate were studied with propano1 and phenylformic acid as reactants and reaction conditions were selected.The results showed that NaHSO_4.H_2O was an excellent catalyst for the synthesis of propy1 benzoate,and the optimum reaction conditions was that the molar ratio of propano1to acid was 3∶1,the mass ratio of the catalyst used to the reactants was 3 %,and the reaction time was 7 h,Under this conditions the yield of propy1benzoate reached 92.6 %.
