气相色谱法测定羟乙基乙二胺的含量

Gas Chromatographic Analysis of Aminoethylethanolamine Obtained by Ethoxylation of Ethylenedia-mine

本文提供了一种测定羟乙基乙二胺(AEEA)含量的简便、快速的气相色谱法,该法适用于由环氧乙烷法合成的AEEA粗产物和蒸馏各馏分中AEEA含量的测定。结果表明,此法对粗产物和目的馏分,相对误差和相对标准偏差均小±2%,对前馏分,则分别小于±4%和±10%,对釜底物,相对标准偏差在±5%以下。

This paper is related to a convenient and rapid method for the gas chromatogra-phic analyses of aminoethylethanolamine(AEEA). This method is suitable for determining AE-EA contens in the crude products obtained by ethoxylation of ethylenediamine and in the front fractions, main fractions and distillation residues. The result showed that the relative err-ores and relative standard deviations were below± 2 % for the crude products and main fractions, and below± 4 % and ±10% for the front fractions respectively. For the residues, the relative standard deviations was less than ± 5 %.
