本文报导用气相色谱研究乙基硫代磺考察其热稳定性,从而验证了乙基硫代磺酸乙酯的热分解机理,选择了合适的色谱条件;并对其主成份及杂质作定性鉴定,测定其重量校正因子;建立了归一、内标及标准曲线三种常用色谱定量方法。所得结果,可用于工厂 In this paper, the gas chromatography was used to study the thermal stability of ethylthio-sulfonate, which verified the thermal decomposition mechanism of ethyl-ethyl-ethylsulfonates and selected suitable chromatographic conditions. The main components and impurities were qualitatively identified , To determine the weight correction factor; established the normalization, internal standard and standard curve of three commonly used chromatographic quantitative methods. The result can be used in factories
