【摘要】 采用气质联用方法对四甲基二乙烯基二硅氧烷样品进行分析,共检出6个组分,经分析为乙醇、二氯甲烷、二甲基乙氧基乙烯基硅烷、四甲基二乙烯基二硅氧烷、四甲基乙烯基丙烯基二硅氧烷和三甲基三乙烯环三硅氧烷。分别对其裂解机理进行讨论,其中多为合成中产生的副产物。对组分含量进行了FID测定,为四甲基二乙烯基二硅氧烷的质量控制和分析提供了依据。更多还原

【Abstract】 Determination of divinyltetramethyldisiloxane using gas chromatography-mass spectrometry(GC-MS).It was found that 6 kinds of compounds including alcohol,dichloromethane,ethoxydimethylvinylsilane,divinyltetramethyldisiloxane,vinyltetramethylpropenyldisiloxane and triethenyltrimethylcyclotrisiloxane.Most of them were by-products in the synthesis process according to discussing fragmentation mechanism separately.Analyzed the component contents by FID provided the basis for quality control and analysis of divinyltetramethyldisiloxane.更多还原
