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