Abstract:
A method for making monomethylamine, dimethylamine and trimethylamine, in which methanol and/or dimethylether and ammonia are contacted in the presence of an acidic zeolite chabazite catalyst is disclosed. The method suppresses the production of trimethylamine and optimizes dimethylamine and monomethylamine yields.
