摘　　要：以等体积浸渍法制备了分子筛Ti-HMS负载碱金属的固体碱催化剂K2O/Ti-HMS,在固体碱催化剂K2O/Ti-HMS作用下,对大豆油制取生物柴油的工艺进行了优化。考察了反应温度、反应时间、K2O负载量、醇油摩尔比和催化剂用量等因素对该反应的影响。结果表明:最佳反应条件是反应温度60℃,反应时间3 h,K2O负载量7mmol.g-1,n(甲醇)∶n(大豆油)=16∶1,催化剂用量为大豆油质量的3%,在此条件下酯交换转化率可达75%以上。The solid base catalysts K2O/Ti-HMS was prepared by impregnation method.The technics of transesterification to produce biodiesel from soybean oil catalyzed by solid base catalyst K2O/Ti-HMS was studied.The effects of reaction temperature,reaction time,K2O load,methanol to oil molar ratio and catalyst dosage were discussed on the reaction.The results showed that the optimal reaction condition was reaction temperature 60℃,reaction time 3 h,K2O loading 7 mmol·g-1,n（methanol）∶n（soybean oil） = 16∶1,catalyst amount of soybean oil quality 3% of the ester exchange under these conditions the conversion of more than 75%.
