Title: Catalysts for producing methylamines

Abstract: Catalysts for producing methylamines are provided, which comprise mordenite, as the essential component, of spherical fine particles having a crystal diameter of not more than 0.5 .mu.m. When the catalysts are used for the production of dimethylamine from methanol and ammonia or through a disproportionation of methylamines, they exhibit a high dimethylamine productivity with the formation of few amount of trimethylamine whose demand is very small. The process can be operated for a long period of time without decrease in the catalyst activity.
