ABSTRACT:
The present invention relates to an improved method for the vinylation of pyrrolidone with acetylene in the presence of an alkali metal salt of said pyrrolidone as a catalyst, by the addition of between about 0.2 and about 8 weight-%, based on total feed, of a polyoxyalkylene glycol; a polyoxyalkylene phenol, optionally substituted with an alkyl group; a polyoxyalkylene ether or mixtures thereof; said polyoxyalkylene compound having a number average molecular weight of between about 175 and 2,000 and containing between 4 and 40 oxyethylene and/or oxypropylene units. The invention also pertains to a novel coacting catalyst composition for use in vinylation reactions comprising said alkali metal salt of said pyrrolidone in admixture with said polyoxyalkylene compound.
