摘　　要：采用GC-FT IR和GC-MS建立环状硫代碳酸酯和环状碳酸酯的分析方法。选用HP-5毛细管色谱柱(30m×320Lm×0.25Lm),分流比50÷1,进样量1LL,进样口起始温度120℃,保持5min,升温速率15℃/min,进样口终止温度270℃。质谱采用EI源,选取Scan模式,扫描范围为50到550m/Z。结果表明GCFT IR可鉴定出3种环状硫代碳酸酯,而GC-M S可同时鉴定出4种环状硫代碳酸酯。Analysis method of cyclic thiocarbonates was established by GC-FTIR and GC-MS. The experimental conditions employed were as follows：HP-5（30m×320μm×0.25μm） ,split ratio of 50 ： 1,injection volume of 1 μL,initial injector temperature of 12℃ firstly maintained for 5min, heating rate of 15℃/min and final temperature of 270℃. Mass spectra were collected by EI source under Scan mode from 50 to 550m/Z. The results show that the GC-FTIR is able to identify three types of cyclic thiocarbonates,and the GC-MS can diagnose four types of cyclic thiocarbonates.
