Process for producing dimethylformamide
 Dimethylformamide mg.multidot.produced by reaction of monomethylamine and trimethylamine at a molar ratio of trimethylamine to monomethylamine of 0.1-10, with carbon monoxide in the presence of 1-500 mg. atom of at least one of iodine, bromine, iodides and bromides as a catalyst in term of halogen per one mole of raw material methylamines at a temperature of 100.degree.-350.degree. C. under a pressure of at least 50 kg/cm.sup.2 gage. Dimethylformamide is produced in a very high yield with a high selectivity from monomethylamine and trimethylamine having less demand among three species of methylamines formed from methanol and ammonia.
