对C.I.分散黄211检测中对氯苯胺呈假阳性结果的探讨

False Positive Detection for 4-Chloroaniline in C.I. Disperse Yellow 211

检测C.I.分散黄211中可裂解禁用芳香胺对氯苯胺时,结果可能存在假阳性。采用GC/MS检测技术进行分析,发现该假阳性检出物为对氯苯胺同分异构体-间氯苯胺,对它的来源进行推断及验证,得出间氯苯胺来源于对氯邻硝基苯重氮盐分解产物的结论,为检测以对氯邻硝基苯胺为原料合成染料中对氯苯胺提供了一定的参考。

A false positive determination for 4-chloroaniline maybe occur in detection of banned aromatic amines of C. I. Disperse Yellow 211. Based on GC/MS, the false positive determination was the isomeride of 4-chloroaniline--3-ehloroaniline, which produced from the secondary reaction of diazonium salt of 4-ehloro-2-nitroaniline. It was a reference for 4-ehloroaniline detection of azo dyes synthesized from 4-chloro-2-nitroaniline.
