摘要： 采用龙氏氮素器对含氢硅油和聚醚硅油中的含氢量进行了测定。其原理是利用Si-H键与NaOH溶液反应产生氢气,通过准确测定生成氢气的体积,由气态方程式即可计算出含氢量,并与化学法进行了对比,结果表明两者间相对偏差均小于3.3%,取得了满意的效果。

关键词: 含氢硅油, 聚醚硅油, 龙氏氮素器, 含氢量

Abstract: The determination of hydrogen content in hydrogen containing silicon oil and polyether silicon oil was conducted with Lunge apparatus,which is originally designed for determination of nitrogen content in organic materials.Its principle is based on the reaction between NaOH and Si-H bond with generation of hydrogen gas and the volume of the hydrogen gas is accurately measured.Then the hydrogen content can be determined via gas equation calculation.The results were compared with that obtained from chemical analysis method and showed that the relative deviation is less than 3.3%,which denotes that the method is satisfactory in practice.

Key words: hydrogen containing silicon oil, polyether silicon oil, Lunge apparatus for nitrogen determination, hydrogen content
