| Abstract: | Solid super acid SO4/TiO2/La3 was prepared and used for the catalytic synthesis of isoamyl propionate.The yield of isoamyl propionate reaches 95.7% under the proper conditions.It was shown that the proper conditions were as follows: the reacting time was 2 h,the molar ratio of isoamylol to propionic acid =1.6,the weight of the catalyst was 0.8 g(when propionic was 0.2 mol),the amount of the dewatering reagent toluene was 12 mL. |
