摘要
多氯联苯(PCBS)是有毒物质,PCBS具有化学和热的稳定性。该文用亲核取代热分解法破坏多氯联苯。这是在深入研究卤代烃亲核取代理论和结焦作用的基础上提出的。销毁是在密闭反应器中进行的,因此对水和空气没有污染。反应条件较温和,设备简单,PCBS降解率近100%。
Polychlorobiphenyl (PCB s ) is a kind of toxic substance, mainly acts as dielectrics in an electric capacitor. PCB s has chemical and thermal stability, and its destruction is an extensively studied topic in the world, but at present there is not a method that is saticfactory economically and technologically. The method that this paper states is based on the thorough study of nucleophilic substitution and related theories. The paper introduces the theoretic analysis, experimental method and results. Destruction is conducted in an airtight reactor, therefore, there is no pollution for water and atomsphere. Reaction conditions are rather gentle, equipments are simple, destroying efficiency of PCB s amounts to near 100%.
