摘    要:用毛细管气相色谱-质谱联用技术对润滑油溶剂精制中回收溶剂N-甲基吡咯烷酮(NMP)中残留的有机酸进行了研究;对这些有机酸的甲酯化物色谱分离出26个甲酯峰,由GC/MS确定了其中的17个主要成份,约占有机酸甲酯总量的90.81%。色谱还分离出一个二重峰,占整个样品总量的86.53%,GC/MS确定其为4-甲氨基丁酸和NMP,从而得到了循环溶剂NMP中存在氧化水解产物的证据。

关 键 词:NMP,气相色谱,质谱,有机酸甲酯

Abstract:In this paper, methyl esters of organic acids left over in the retrieved circulating solvent N-methylpyrrolidone of solvent-refined lubricating oil hase been studied by capillary gas chroma-tography/mass spectrometry.About 26 methyl ester peaks were discerned by GC,of which 17 organic acids,constituting about 90.81%of methyl ester,were identified by MS.And a double peakwas separated by GC,which was butanoic acid 4-methvlamino and NMP.The results provide ascientific basis for anti-corrosion measures of the chemical industry.
Keywords:NMP  gas chromatography  mass spectrometry  methyl ester of organic acid
