Abstract
Manufacture of amines by reacting alcohols with ammonia in the presence of a catalyst comprising zeolite FU-1 in which some or all of the protons of the zeolite have been replaced by monovalent cations, for example sodium. The process is especially useful for the manufacture of methylamines in which the proportions of monomethylamine and dimethylamine obtained are selectively increased in preference to trimethylamine.
