【摘要】 本文首次对硅 - 6 0 2交联剂的组分进行了研究报道 ,样品在温岭GC9790色谱仪的SE5 4(2 0m× 0 .2 5mm× 0 .2 5 μm)石英毛细管柱中程序升温 :从 5 0℃ (2min)开始以 8℃ /min升温到 2 5 0℃ (10min) ,分离得到了六个分离很好的色谱峰以及各组分的含量 ;然后用ThermoQuest公司的TraceGC/MS仪对各组分进行定性分析 ,得到样品各组分的质谱图并结合质谱裂解规律 ,推测出样品的主要成分为e:[(CH3O) 2 CH3SiCH2 CH2 CH2 NHCH2 CH2 NH2 ],其他杂质依次为a:[(CH3O) 3SiCH3]、b :[(CH3O) 2 CH3SiCH2 CH2 CH3]、c :[(CH3O) 2 CH3Si(CH2 ) 8CH2 NHCH3]、d :[(CH3) 2(CH3O)SiCH2 CH2 CH2 NHCH2 CH2 NH2 ]、f:[(CH3O) 2 CH3SiCH2 CH(CH2 NHCH2 CH2 NHCH3) 2 ]。其中样品的主要成分含量为 96 5 0 % ,其他杂质的总含量为 3 5 0 %。

【Abstract】 The research of the components of the Silane602 was first reported in this paper.Six goodseparate Chromatogram peaks,as well as their contents,were obtained by Gas Chromatogram in the sample.Their molecular structures,which the main component is [(CH 3O) 2 CH 3SiCH 2CH 2CH 2NHCH 2CH 2NH 2],were speculated after applying the technology of gas chromatogram/mass spectrum by the instrument of Trace GC/MS,maded in ThermoQuest company,combined with the mass spectrum splittingdecomposition law.The content of the main component is 96.50 percent while the total content of the impurities is 3.50 percent,which may be byproduced in the process.
