Abstract: A method for conversion of ethylidene N,N'-bis-pyrrolidone, a by-product of the vinylation of 2-pyrrolidone, into 2-pyrrolidone starting material. This method is carried out by heating the by-product at an elevated temperature for a predetermined period of time, and recovering the 2-pyrrolidone conversion product therefrom for recycle into the vinylation process.
