Abstract:
A method for the production of monomethylamine, dimethylamine, and trimethylamine comprising contacting methanol, and/or dimethylether, and ammonia in amounts sufficient to provide a carbon:nitrogen (C:N) ratio from about 0.2 to about 1.5 and at a reaction temperature from about 250.degree. C. to about 450.degree. C., in the presence of a catalytic amount of an acidic molecular sieve which has an AFX crystalline structure, wherein the ratio of silicon to aluminum (Si:Al) in said molecular sieve is greater than about 2.5:1, wherein methanol and/or dimethylether is converted to monomethylamine, dimethylamine, and trimethylamine.
