摘　　要：以磁性材料Fe_(3)O_(4)为核心,经氨基功能化、磷钨酸固载化制备氨基功能化磁性材料固载磷钨酸催化剂(Fe_(3)O_(4)@NH_(2)-PW),并考察其在棕榈酸与甲醇酯化制备生物柴油反应中的催化性能,同时通过响应面法优化制备工艺。研究结果表明,催化剂Fe_(3)O_(4)@NH_(2)-PW具有较好的催化酯化反应活性、稳定性及易分离性能;以Fe_(3)O_(4)@NH_(2)-PW为催化剂,在甲醇与棕榈酸摩尔比7.4∶1.0,Fe_(3)O_(4)@NH_(2)-PW量为棕榈酸质量的4.5%,90℃,反应时间3.3 h的响应面优化最佳条件下,获得96.9%生物柴油产率,该结果与模型预测值(97.08%)基本吻合。In this study,with Fe_(3)O_(4)as the core,amino-functionalized magnetic material supported phosphotungstic acid catalyst(Fe_(3)O_(4)@NH_(2)-PW)(Fe_(3)O_(4)@NH_(2)-PW)was prepared.The catalytic performance of Fe_(3)O_(4)@NH_(2)-PW was evaluated for the esterification of palmitic acid and methanol.At the same time,the preparation process was optimized by response surface methodology.The results indicated that Fe_(3)O_(4)@NH_(2)-PW catalyst exhibited good catalytic activity,stability and easy separation during esterification.With Fe_(3)O_(4)@NH_(2)-PW used as the catalyst,96.9%biodiesel was obtained under optimal response surface conditions of methanol/palmitic acid molar ratio of 7.4∶1,Fe_(3)O_(4)@NH_(2)-PW amount of 4.5%of palmitic acid,90℃,and 3.3 h.The results were in good agreement with the predicted value of 97.08%.
