    • 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.
    • 在氨或甲酰胺与CO和H 2的催化反应中,当在可溶于反应介质的铂族催化剂存在下进行反应时,在反应产物中获得了特别高的单 - 和二 - 甲基甲酰胺的产率, 特别是钌或铑的化合物或络合物,其使用不含活性甲基官能团并且不进入生成甲酰胺化合物的反应的相对非挥发性极性溶剂。 所用的压力在3000-8000psi的范围内,氢分压至少为1500psi,优选的溶剂是环丁砜。
