ABSTRACT:
Upon subjecting trimethylamine with ammonia and optionally, a methylamine to a disproportioning reaction to reduce the proportion of the trimethylamine, use of a zeolite as a catalyst, said zeolite being mordenite, clinoptilolite or the like at least 80% of whose ion-exchangeable cations being in the form of hydrogen ions, makes it possible to efficiently conduct the reaction at a low reaction temperatures and also to suppress by-production of impurities such as acetonitrile.
