摘　　要：以油酸甲酯(MO)为植物油脂模型物,通过烯烃复分解反应制备1-癸烯,以油酸甲酯转化率和1-癸烯得率为评价指标,探究了反应底物、催化剂类型、反应温度、反应时间、催化剂用量和MO与反应底物物质的量之比对烯烃复分解反应制备1-癸烯的影响,最后通过正交试验设计优化得到最佳工艺条件。结果表明:反应底物丁香酚和Grubbs第二代催化剂C2有利于本反应体系,最佳工艺条件为反应温度0℃,反应时间40 min,催化剂C2用量1%,n(MO)∶n(丁香酚)1∶10,在此条件下MO转化率和1-癸烯得率分别为96%和78%。1-Decene was prepared through olefin metathesis reaction using methyl oleate(MO)as the vegetable oil model chemistry,the conversion rate of methyl oleate and yield of 1-decene were used as evaluation indicators to explore the effect of reaction temperature,reaction time,catalyst dosage and molar ratio of substrates to MO,finally the optimal conditions were obtained by orthogonal experiment design.The results showed that the substrate eugenol and Grubbs second-generation catalyst(C2)were beneficial to the reaction system.The optimal conditions were reaction temperature 0℃,reaction time 40 min,catalyst dosage 1%,molar ratio of MO and eugenol 1∶10,under these conditions the conversion rate of MO and the yield of 1-decene were 96%and 78%,respectively.
