| Abstract: | The synthesis of iso-amyl benzoate were studied with iso-amyl alcoho and phenylformic acid as reactants,and reaction conditions were selected. It showed that TiSiW12O40/TiO2 was an excellent catalyst for the syn-thesis of iso-amyl benzoate, and the optimun reaction conditions was that the molar ratio of pentyl to acid was 4:1, the mass ratio of the catalyst used to the reactants was 2.5% , and the reaction time was2.5h. Under this conditions, the yield of iso-amyl ben-zoate reached 83.3%. |
