硅烷偶联剂 Si-69中单质硫与化合态硫的液相色谱分析研究
The Liquid Chromatography Analysis of the Elemental and the Combined Sulfur in Silane Coupling Agent Si-69
摘要
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 .关键词
