Abstract: A process for making 3-methylpyridine comprises contacting 2-methylglutaronitrile in admixture with hydrogen gas with a supported solid catalyst containing palladium metal promoted with at least one of Cr, W, Ni, Co and Ge. A preferred support contains from zero to 30 weight percent of silica and 100 to 70 weight percent alumina. The usual reaction temperatures are about 250 to 320°C.
