A Vinyl-2-pyrrolidinone. l-Ethenyl-2-pyrrohdinone [88-12-0] C H NO, A/-vinylpyrrohdinone, was developed by Reppe s laboratory in Germany at the beginning of World War II and patented in 1940 (215). [Pg.114]

Vinyl etheis serve as a source of vinyl groups for transvinylation of such compounds as 2-pyrrolidinone or caprolactam (240,241). Compounds such as carbon tetrachloride (242) or trinitromethane (243) can add across the double bond. [Pg.116]

Methyl-2-Pyrrolidinone. N-Meth5l-2-pyrrohdinone [872-50-4] (44) (NMP or methyl-2-pyrrohdone, M-Pyrol) was fkst reported in 1907 as prepared by alkylation of 2-pyrrohdinone with methyl iodide (81). The present commercial route, ie, condensation of butyrolactone with methylamine, was first described in 1936 (50). [Pg.361]

A Vinyl-2-Pyrrolidinone. Commonly called vinylpyrrohdinone or VP, Al-vinyl-2-pyrrohdinone was developed in Germany at the beginning of World War 11. It is a clear, colorless Hquid that is miscible in all proportions with water and most organic solvents. It can polymerize slowly by itself but can be easily inhibited by small amounts of ammonia, sodium hydroxide (caustic pellets), or antioxidants such as N,lSf-di-j i -butyl- -phenylenediamine. It...
