摘　　要：介绍了一种利用负载型催化剂将3-甲基吡啶催化脱甲基合成吡啶的研究,系统地考查了催化剂制作成分、反应温度、反应气量、反应浓度等因素的影响,筛选出合适的催化剂成分及反应条件。经过筛选,在最合适的催化剂及最佳反应条件下,3-甲基吡啶能够较好较快地脱甲基生成吡啶,吡啶收率达到55%,3-甲基吡啶转化率达到80%,选择性为70%左右。该工艺简单快捷,节能环保,催化剂可以重复使用。This paper introduces the study of a supported catalyst for the synthesis of 3-methyl pyridine,systematically in-vestigated the catalyst composition,reaction temperature,reaction volume,reaction concentration and other factors,and screened out the appropriate catalyst composition and reaction conditions.After screening,the most appropriate catalyst and the optimal reaction conditions,3-methyl pyridine can better faster methyl pyridine,pyridine yield of 55%,3-methyl pyridine conversion of 80%,selectivity is about 70%,the process is simple and quick,energy saving and environmental protection,catalyst can be used repeatedly.
