Method for preparing methylamines |
摘要 |
A method for selectively preparing dimethylamine and monomethylamine, while the production of trimethylamine is inhibited to a sufficiently low level. The method comprises carrying out a gaseous reaction of methanol and ammonia by the use of a mordenite modified with a silylating agent by a silylation treatment in a liquid phase. According to the present invention, recycling trimethylamine is unnecessary, and the amount of steam or the like to be used can be decreased.
