PROCESS FOR PREPARING N-VINYL AMIDES |
摘要 |
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: <IMG> 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 150.degree.-350.degree.C, in the presence of a porous, hydrogen-abstracting catalyst.
