PROCESS FOR MICROWAVE ASSISTED SYNTHESIS OF N-METHYL PYRROLIOONE

摘要

The present invention relates to a process for microwave assisted synthesis of N-methyl pyrrolidone (NMP). Particularly the process relates to the synthesis of N-methyl succinimide or corresponding analogues by using microwave irradiation which on hydrogenation in the presence of a hydrogenating catalyst gives N-methyl pyrrolidone. Compared to the conventional heating microwave process requires less energy inputs and reduces the reaction time drastically from 5-6 h to 2-5 min.
