Process for preparing N-vinyl amides.

摘要

N-vinyl amides having the general structural formula: CH2 = CH-NHCOR<1> wherein R<1> 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: <CHEM> wherein R<1> is as described above, and R<2> is a C1 to C9 alkoxy, carboxy or carboxamide group. Said carboxylic acid amides are cracked by heating, to a temperature of about 150 DEG -350 DEG C, in the presence of a porous, hydrogen-abstracting catalyst.
