Abstract
Trimethylamine and triethylamine are obtained by passing vaporized dimethylamine or diethylamine over a catalyst of the dehydrating type at a raised temperature and preferably at a raised pressure. Specified catalysts are aluminium oxide, thorium oxide, molybdenum oxide, tungsten oxide, aluminium silicate, aluminium phosphate, silica gel, and kaolin; the catalyst may contain a small proportion of an activating substance, e.g. chromium oxide, zinc oxide, zinc phosphate, cerium oxide, titanium oxide or vanadium oxide; carriers such as pumice may be employed. In the examples: (1) dimethylamine is passed at 380 DEG C. and 200 atm. pressure over alumina gel, and the products are condensed under 10 atm. pressure; a mixture of ammonia and methylamines containing 64 per cent of trimethylamine is obtained, and is separated by fractional distillation under pressure; triethylamine is obtainable similarly from diethylamine; (2) dimethylamine is passed at 370 DEG C. and 10 atm. pressure over a catalyst comprising aluminium oxide and kaolin, and the product is worked up as in example 1; (3) dimethylamine is passed over aluminium oxide at 370 DEG C., and the product is worked up as in example 1.
