METHOD FOR CONVERSION OF DIAMMONIM SUCCINATE IN FERMENTATION BROTH TO 2- PYRROLIDONE AND N-METHYL PYRROLIDONE.This invention relates to a process for prepg. 2-pyrrolidone (also called 2-pyrrolidinone) and N-methyl pyrrolidone (also called N-methyl pyrrolidinone) from diammonium succinate in fermn. broth. In the first stage of this invention, renewable carbon resources are utilized to produce diammonium succinate through biol. fermn. In the second stage of this present invention, diammonium succinate is converted into 2-pyrrolidone and N-methyl pyrrolidone through a two step reaction. Both the steps of the reaction leading to the prodn. of 2-pyrrolidone and N-methyl pyrrolidone are carried out in a solvent phase to prevent the loss of succinimide through hydrolysis.
