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.
