ABSTRACT:
In the catalytic reaction of ammonia or formamide with CO and H.sub.2, exceptionally high yields of mono- and di-methyl formamide are obtained among the reaction products when the reaction is carried out in the presence of a platinum group catalyst soluble in the reaction medium, particularly a compound or complex of ruthenium or rhodium, employing a relatively non-volatile polar solvent which does not contain an active methyl function and which does not enter into the reaction producing formamide compounds. The pressure employed is in the range of 3000-8000 psi with a hydrogen partial pressure of at least 1500 psi, the preferred solvent being sulfolane.
