气相色谱法分析己二胺残液
首发时间:2008-10-08
摘要:本文研究了采用DB-1毛细管柱气相色谱法定性、定量检测己二胺合成残液中的主要化合物质。运用保留时间法定性得出己二胺残液中主要含有丙二胺、丁二胺、己二胺3种脂肪二胺,并运用外标法定量了各物质的含量,该方法的精密度(RSD)为0.12%~0.24%,加标回收率在95.0%~101.1%之间,有操作简便快捷、精密度好、准确度高的特点。

Determination of hexane diamine residual liquid by gas chromatography
Abstract:In this paper,Gas chromatography with DB-1 capillary column is used to determine the nature and the quantity of aliphatic diamines in hexane diamine residual liquid as follows:the use of time retention method to know that hexane diamine residual liquid contains three kinds of aliphatic diamines(propane diamine, butane diamine and hexane diamine)and the use of area-external standard method to measure their contents.The relative standard deviation are between 0.12%~0.24% and the recoveries are between 95.0%~101.1%.The method has the advantages including rapid and simple operation,high accuracy and high precision.
Keywords: gas chromatography propane diamine butane diamine hexane diamine
