Abstract

1379806 Thioformamide MERCK & CO Inc 13 Dec 1972 [20 Dec 1081] 57484/72 Heading C2C Thioformamide is made by reacting hydrogen cyanide and hydrogen sulphide in an organic solvent in the presence of a basic ion-exchange resin as a catalyst. The reaction may be performed continuously by passing the reagents over a column of the resin.
