| 摘 要： | 使用液相色谱及液质联用技术建立了硅烷偶联剂Si-69中单质硫和化合态硫各自含量的分析方法.以C8柱为液相分离柱,采用简单的甲醇-水流动相体系进行梯度淋洗,Si-69各组分得到了很好的分离.Si-69样品中鉴定出单质硫,并根据外标法测得其质量分数为16.8mg/g.同时,对样品中含硫化合物进行分析、鉴定,计算出化合态硫质量分数为28.26%,平均硫链长为3.55.本方法操作简单、快速,可用于Si-69的硫质量控制分析.

| Abstract: | In this study,the method for analyzing the content of the elemental and the combined sulfur in silane coupling agent Si-69 is established by liquid chromatography and liquid chromatography-mass spectrometry.Every component in Si-69 is well separated by using gradient elution with the simple mobile phase system of methanol-water.Elemental sulfur is detected in Si-69 samples,and quantitated to be 16.8 mg/g according to the external standard method.In addition,the combined sulfur content is determined to be 28.26% and the length of average sulfur chain to be 3.55.This method is simple and fast,and suitable for sulfur quality control analysis of Si-69. |
