N-methyl pyrrolidone is a good chemical industrial solvent. This paper analyzed the domestic and foreign market of N-methyl pyrrolidone and its synthesis technology, which consists of methods prepared from gamma-hutyrolactone and monomethyl amine with or without catalyst , or using mixing methyl amine instead of monom- ethyl amine. In addition, an integration process from 1,4-butanediol to produce gamma-butyrolactone and further-more to produce N-methyl pyrrolidone has also been analyzed. In the end, a suggestion about development of N-methyl pyrrolidone project has also been proposed.
