气相色谱法检测硅酮密封胶的交联剂和偶联剂的纯度

Determination of the Purity of Crosslinker and Coupling Agent of Silicone Sealant by GC

采用气相色谱法,根据相似相溶的踏板洗脱原理,采用非极性高性能毛细管色谱柱检测硅酮密封胶的常用交联剂(甲基三丁酮肟基硅氧烷、乙烯基三丁酮肟基硅氧烷)和偶联剂(N-β-(氨乙基)-γ氨丙基三甲氧基硅烷、γ-氨丙基三乙氧基硅烷、四丙氧基硅烷)的纯度。

According to the pedal elution principle of similar compatibilit,Detection of the Purity of common crosslinking agents(Methyl tributyl ketone oxime siloxane and vinyl tributyl ketone oxime siloxan)and coupling agents(N-beta-(aminoethyl)-gamma-aminopropyl trimethoxysilane、gamma-aminopropyl triethoxysilan and tetrapropoxysilane)in silicone sealants by non-polar high performance capilla by GC.
