ABSTRACT:
A process for the manufacture of methylamines comprises reacting a feed comprising methanol and/or dimethylether and ammonia over a binderless zeolite A catalyst, preferably a binderless zeolite 5A catalyst. Use of binderless zeolite 5A makes the process attractively selective to dimethylamine in preference to mono- and tri-methylamine. In addition, if the catalyst is essentially free of alkali metal it is not only more active than similar catalysts containing alkali metal but also considerably more selective.
