PROBLEM TO BE SOLVED: To provide a method for efficiently obtaining N,N-dimethylformamide by oxidizing trimethylamine with molecular oxygen. SOLUTION: This method for producing N,N-dimethylformamide is to oxidize trimethylamine with an oxygen-containing gas in the presence of a catalyst comprising one or more noble metals selected from the group consisting of ruthenium, rhodium, palladium, osmium, iridium and platinum, and one or more elements or compounds of the elements selected from the group consisting of lead, tin, bismuth, molybdenum, tellurium, cerium and antimony. The objective product is obtained directly in one step from triethylamine produced in excess than the demand without the need of any sub-material, e.g. carbon monoxide. |
