| Abstract: | Isoamyl benzoate was synthesized by esterification of benzoic acid and isoamyl alcohol over Ti(SO4)2/SiO2 catalyst. The influences of various factors were investigated. Optimum reaction condition was obtained as follows: titanium sulfate loading on SiO2 =10% (mass fraction); m(catalyst)∶m(benzoic acid)=2.5 g∶0.05 mol, n(isoamyl alcohol)∶n(benzoic acid) = 4∶1, reaction time 90 min. Esterification of 96.6% was attained under the optimum condition. |
