This work investigated the distribution of chlorine element in Zhongjie (ZJ) crude oil via microcoulomb titrameter and salt content determinator. The species and content of organic chlorides in light distillates (&lt;300 °C) were determined by gas chromatography equipped with electron capture detector (GC–ECD). The content of organic chloride in ZJ crude oil was 6.33 mg/L, and organochlorine compounds were found in each distillate of ZJ crude oil. The content of organochlorine in naphtha, kerosene, and light diesel were 6.59, 4.43, and 3.24 mg/L, respectively. The species of organic chlorides in naphtha, kerosene, and light diesel were similar. Trichloromethane, carbon tetrachloride, trichloroethylene, tetrachloroethylene, 1,1,2,2-tetrachloroethane, 1,1,1,3-tetrachloropropane, and 1,2,4-trichlorobenzene were all identified from three kinds of light distillates of ZJ crude oil. The gas chromatography quantitative analysis results of organic chloride in light distillates (&lt;300 °C) illustrated that a large proportion of organic chlorides had been identified.
