摘　　要：3_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_hexenediacylchloride,COHC)。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.
