Abstract

PURPOSE: To prepare the titled substance useful as a catalyst, easily and safely, by reacting diethylene glycol or 2-[2-(N,N-dimethylamino)ethoxy]ethanol with dimethylamine in a closed vessel in the presence of a copper-based catalyst under specific condition.
CONSTITUTION: The objective compound is prepared by reacting diethylene glycol or 2-[2-(N,N-dimethylamino)ethoxy]ethanol with dimethylamine in a closed vessel in the presence of hydrogen and a copper-based catalyst, e.g. Raney-Cu catalyst, copper chromium catalyst, etc. at about 150W300°C, especially about 200W250°C, and subjecting the partly by-produced secondary amino compound to the methylation reaction without separating from the reaction system. The amount of the dimethylamine is preferably about 3W4mol per 1mol of diethylene glycol and about 1.5W2mol per 1mol of the other raw material.
