ABSTRACT:
Ethylidene bisformamide is produced in high selectivity by the reaction of formamide with vinyl acetate in a molar ratio of at least 1:1 at a temperature from about 60.degree. to 150.degree. C. in the presence of a catalyst comprising an acid salt of mercury of which the parent acid has a pKa less than about 3.8.
