Beschreibung
Zusammenfassung:	N-vinyl amides having the general structural formula: CH2=CH-NHCOR1 wherein R1 is hydrogen, a C1 to C6 alkyl group or a C6-C9 aryl or substituted aryl group, are formed by cracking carboxylic acid amides having the general structure formula: wherein R1 is as described above, and R2 is a C1 to C9 alkoxy, carboxy or carboxamide group. Said carboxylic acid amides are cracked by heating, to a temperature of about 210 DEG -350 DEG C., in the presence of a catalyst comprising MgS or an oxide or mixed oxide of Ca or Sr.
