ABSTRACT:
Dialkyl formamides may be prepared by treating the corresponding dialkyl amine with carbon dioxide and hydrogen in the presence of a transition metal hydrogenation catalyst at a temperature in the range of from about 100.degree. to about 400.degree. C. and a pressure in the range of from about 5 to about 300 atmospheres. The reaction is exemplified by treating dialkyl amine with carbon dioxide and water in the presence of a copper chromite to form N,N-dimethylformamide.
