NMP (N-methylpyrrolidone), as an important organic solvent, is widely used in fields such as lithium - battery electronics processes and chemical polymerization. Due to high market demand, its price has remained at a high level. In particular, there is a huge supply gap for high - purity NMP raw materials. The latest progress in the optimization of production and recycling technologies, equipment upgrades, and green development of NMP in major application fields were reviewed. The application of recycling technologies such as distillation, membrane separation technology, extractive distillation, multi - tower combined - effect distillation, and dividing - wall distillation columns has improved the recovery efficiency and purity of NMP. With the rapid development, technological innovation, and policy support in industries such as new energy electronics, the NMP industry will continue to develop in the direction of green sustainability.
