Chlorinated paraffins (CPs) are high production volume chemicals currently produced and used in higher quantities than any other medium-size polyhalogenated compound (class). In addition, the composition of industrial CP mixtures is highly complex and poorly understood. In this article, we searched in the literature for the beginning of the chlorination of alkanes and how this substance class developed from niche applications to unmatched quantities in various industrial applications. Also, an estimation was made on the theoretical variety of chloroparaffins and the possible complexity of industrial CP mixtures. These data may explain why little is known about CPs although the production volume throughout the industrial generation was virtually always higher than the one of PCBs and has continued to increase after the ban of the latter.
氯化石蜡（CPs）是一种高产量化学品，目前的产量和使用量均高于其他任何中体型多卤化化合物（类别）。此外，工业 CP 混合物的组成非常复杂，人们对此了解甚少。本文从文献中搜索了烷烃氯化的开始，以及此类物质如何从利基应用发展到在各种工业应用中达到无可比拟的数量。此外，还对氯化石蜡的理论种类和工业 CP 混合物的可能复杂性进行了估算。这些数据可能解释了为什么尽管 CPs 的产量在整个工业生产中几乎一直高于 PCB，并且在后者被禁止后仍在继续增加，但人们对其了解甚少。
