摘　　要：2-甲基吡啶可以用作合成医药、染料的原料和中间体。利用表面活性剂十六烷基三甲基溴化铵(CTAB)制备出微介孔型ZSM-5。将微介孔型ZSM-5通过浸渍法负载Ti和V,制备出负载型催化剂。其中微介孔型1%Ti1%V/ZSM-5具有最好的醇氨法催化生成2-甲基吡啶的活性。通过探究不同的温度、压力和反应物摩尔比对反应的影响,最终2-甲基吡啶的收率达到23.7%。2-Methylpyridine can be used as a raw material and intermediate for synthesizing pharmaceuticals and dyes.Preparation of micro mesoporous ZSM-5 using surfactant cetyltrimethylammonium bromide(CTAB).The micro mesoporous ZSM-5 was loaded with Ti and V by impregnation method to prepare a supported catalyst.Among them,the micro mesoporous 1%Ti1%V/ZSM-5 has the best catalytic activity for the production of 2-methylpyridine by the alcohol ammonia method.By exploring different temperatures,pressures,and reactant molar ratios,the final yield of 2-methylpyridine reached 23.7%.
