英文摘要	By studying the hydrolysis of N-methylpyrrolidone, it was found that the effects of NaOH concentration and temperature on N-methylpyrrolidone's hydrolysis were remarkable. Fourier transform infrared (FTIR) and Gel Permeation Chromatography (GPC) detected that the mainly hydrolyzate was 4-(methylamino)butyric acid, and the hydrolyzate can generate polymers, which of molecular weight increases with temperature rising. The results of Gas Chromatography (GC) and moisture meter test showed that adding alkaline and raising temperature can aggravate hydrolysis of NMP. This study provide theoretical basis for recycling solvent (NMP) in the production of polyphenylene sulfide (PPS). © Published under licence by IOP Publishing Ltd.
