摘　　要：二乙基羟胺是共轭烯烃的高效阻聚剂,提出采用气相色谱法进行测定二乙基羟胺的纯度及其中二乙胺、三乙胺等各组分含量,采用HP-INNOWAX毛细管柱测定二乙基羟胺中的水分。在本文提出的条件下,二乙基羟胺与其他各组分能够得到良好的分离,方法方便快捷,结果准确可靠。DEHA is a highly effective inhibitor of conjugated olefins.It is proposed to use gas chromatography to determine the purity of DEHA and the content of diethylamine,triethylamine and other components in DEHA(using DB-1 capillary column and FID detector),and HP-INNOWAX capillary column(TCD detector)to determine the moisture in DEHA.Under the conditions proposed in this paper,DEHA and other components can be well separated.The method is convenient and fast,and the results are accurate and reliable.
