氯苯类化合物是一类苯环上连有1～6个氯取代基且具有强烈气味的单环芳香族化合物,包括一氯苯、二氯苯(包括邻二氯苯、间二氯苯、对二氯苯)、三氯苯(包括1,2,3-三氯苯、1,2,4-三氯苯、1,3,5-三氯苯)、四氯苯(包括1,2,3,4-四氯苯、1,2,3,5-四氯苯、1,3,4,5-四氯苯)、五氯苯以及六氯苯共12种化合物[1].该类化合物广泛应用于农药、药物、染料和塑料等合成生产中.不同氯苯化合物理化性质不同,一氯苯、1,2-二氯苯、1,3-二氯苯与1,2,4-三氯苯主要以蒸气状态存在于工作场所空气中,而其余的1,4-二氯苯和1,2,3-三氯苯等8种氯苯类化合物主要以蒸气和气溶胶两种状态存在于空气中.

氯苯类化合物的理化性质稳定,生物降解困难;具有亲脂性,可通过食物链发生生物富集作用蓄积于体内;具有致畸、致癌、致突变等作用.目前,我国氯苯类产品的生产能力和消费能力均居世界,分别占全球总规模的74％和65％.该类化合物生产中常伴随熔融、氯化、蒸馏等高温工艺,使其常以蒸气态和/或气溶胶态广泛存在于工作场所空气中.而目前针对空气中氯苯类化合物的检测,国内外尚无统一的标准方法.

Chlorobenzene compounds are a class of monocyclic aromatic compounds with 1 to 6 chlorine substituents connected to the benzene ring and having a strong odor, including monochlorobenzene, dichlorobenzene (including o-dichlorobenzene, m-dichlorobenzene, p-dichlorobenzene), trichlorobenzene (including 1,2,3-trichlorobenzene, 1,2,4-trichlorobenzene, 1,3,5-trichlorobenzene), tetrachlorobenzene (including 1,2 ,3,4-tetrachlorobenzene, 1,2,3,5-tetrachlorobenzene, 1,3,4,5-tetrachlorobenzene), pentachlorobenzene and hexachlorobenzene, a total of 12 compounds [1]. Chlorobenzene compounds are widely used in the synthesis and production of pesticides, drugs, dyes and plastics. Different chlorobenzene compounds have different physical and chemical properties. Monochlorobenzene, 1,2-dichlorobenzene, 1,3-dichlorobenzene and 1,2,4 -Trichlorobenzene mainly exists in the air of the workplace in the state of vapor, while the remaining 8 chlorobenzene compounds such as 1,4-dichlorobenzene and 1,2,3-trichlorobenzene are mainly in the state of vapor and aerosol exists in the air.

Chlorobenzene compounds have stable physical and chemical properties, and are difficult to biodegrade; they are lipophilic and can be accumulated in the body through bioaccumulation in the food chain; they have teratogenic, carcinogenic, and mutagenic effects. At present, the production capacity of chlorobenzene products in my country The production capacity of these compounds ranks first in the world, accounting for 74% and 65% of the global total respectively. The production of such compounds is often accompanied by high-temperature processes such as melting, chlorination, and distillation, making them widely available in vapor and/or aerosol states. Exist in the air of the workplace. At present, there is no unified standard method for the detection of chlorobenzene compounds in the air at home and abroad.


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. reviewed the sampling media, sample processing and sample detection of various detection methods, in order to provide a reference for the establishment of a unified detection method for 12 chlorobenzene compounds in the air.
