| titleOfInvention | Process for the recovery of 2-pyrrolidone |
| abstract | A process for the recovery of 2-pyrrolidone from the aqueous reaction product obtained in the preparation of 2-pyrrolidone from the hydrogenation of succinon i trile and subsequent reaction with water of the hydrogenation product thus obtained. The aqueous reaction mixture is adjusted to a pH value of 7 or lower and extracted with chloroform or methylene chloride to form an organic phase containing substantially all of the 2-pyrrolidone. The 2-pyrrolidone can be recovered from the organic phase by distillation, or by further extraction with water followed by crystallization from the aqueous phase thus formed or by evaporation of water. |
