摘要： This paper describes a GC analytical method in the synthes is of N-methyl pyrrolidone of a-pyrrolidone.This procedure was performed with a column packed with 6%OV-17/silanized 101 support and FID detec-tor. Calibration factors and detection conditions are given,The coefficients of variation of NMP and a-P were0.6%and 0.5%respectively. The relative errors of all the components were not more than±3.0%,Thequantitative analysis is fast,simple and accurate.
