摘要
考察了 Ti(SO4 ) 2 /Si O2 在油酸丁酯合成反应中的催化性能 ,对影响酯化的条件进行了优化 ,优化条件如下 :0 .2 g Ti(SO4 ) 2 /g Si O2 ,油酸 0 .1 mol,丁醇 0 .2 mol,催化剂 1 g,反应温度 1 40°C,反应时间 6 0 min。优化条件下 ,油酸的酯化率 98%,收率 91 %。
Ti(SO 4) 2/SiO 2 was used as catalyst for the to esterification of oleic acid with butanol. The reaction conditions were studied. The optimun conditions were as follows:0.2 g Ti(SO 4) 2/gSiO 2 oleic acid 0.1 mol, butanol 0.2 mol, catalyst 1 g, reaction temperature 140 °C , reaction time 60 min. Under the optimun conditions, the conversion of oleic acid was 98%, the yield was 91%.
