| Abstract: | Synthetic method of benzyl propionate was investigated using silicon dioxide supported on phosphotungstic acid. The effects of quantity and stability of catalyst , propionic acid/benzyl alcohol molar ratio, reaction time and temperature on the yield of benzyl propionate have been investigated. Results showed the yield was over 76.3% under optimum condition. It proves that silicon dioxide supported on phosophtungstic acid is a high active catalyst for benzyl propionate and can be reused. |
