摘要
通过水热法制备了锆基金属有机框架(Zr-MOF-808)固载磷钼酸(HPMo)复合催化剂,利用FTIR、XPS、SEM-EDS、N2吸附脱附等表征技术对其结构及形貌进行表征分析,并将其应用于催化油酸(OA)与甲醇的酯化反应.经过工艺优化后的最优酯化反应条件为:反应时间为 3 h、催化剂用量为0.15 g、反应温度为150℃、油酸与甲醇物质的量比为1∶20,在此条件下OA转化率达87.7%,且催化剂重复使用6次后HPMo/Zr-MOF-808仍保持较高活性.
Abstract
Zirconium-based metal organic framework(Zr-MOF-808)supported phosphomolybdic acid(HPMo)composite catalyst was prepared by hydrothermal method.The structure and morphology of composite were characterized using FTIR,XPS,SEM-EDS,N2 adsorption and desorption techniques,and applied to catalyze the esterification reaction of oleic acid(OA)with methanol.The optimal esterification reaction conditions after process optimization were determined as follows:reaction time 3 h,catalyst dosage 0.15 g,reaction temperature 150℃,molar ratio of oleic acid to methanol 1∶20.Under these conditions,the OA conversion rate reached 87.7%,and the HPMo/Zr-MOF-808 still had good catalytic activity after 6 cycle experiments.
