| 摘 要： | 2－氯－4－（二氯甲基）－5－羟基－2（H）－呋喃酮（MX）是饮用水氯化消毒过程中产生的一种具有强致突变性的消毒副产物（DBPs)，在对MX的前驱物模拟氯化过程中，发现在MX峰的附近有一峰，有时干扰MX的测定；作者对该未知峰的质谱图进行了解析，初步推断其结构可能为2－氯－5－酮－3－烯－己二酰氯（2－chloro-5-oxo-3-hexene diacyl chloride,COHC).

| Abstract: | Chloro-4-(dichloromethyl)-5-hydroxy-2(5H)-furanone(MX) is a chlorination by-product in water, which has a strong matagenic property. It is found that in selected ion chromatograms of precursors of MX appeared a peak near MX which can be interfere the detection of MX. The molecular structure of the new chlorination by-product was studied by mass spectrography. It is probably 2-chloro-5-oxo-hexene diacyl chloride(COHC). The dissociation processes of COHC were proposed. |
