Abstract

The reaction of Sovol technical-grade mixture of polychlorinated biphenyls with sodium methoxide in dimethyl sulfoxide and ethanol medium has been studied for the first time by thermodynamic modeling. The addition of ethanol co-solvent to dimethyl sulfoxide has been found to result in the emergence of solvolysis process. The optimal conditions for nucleophilic substitution reaction have been found. Using these reactions, derivatives of polychlorinated biphenyls with decreased chlorine content have been synthesized. A high conversion of initial polychlorinated biphenyl congeners of Sovol mixture has been reached. The studied reaction can serve as a pretreatment stage for the destruction of toxic polychlorinated biphenyls by thermal methods.

多氯联苯与甲醇钠在乙醇和二甲基亚砜溶液中反应的热力学方面

摘要

通过热力学模型首次研究了Sovol工业级多氯联苯与甲醇钠在二甲亚砜和乙醇介质中的反应。已经发现将乙醇助溶剂添加到二甲亚砜中导致溶剂分解过程的出现。已经发现亲核取代反应的最佳条件。使用这些反应，合成了氯含量降低的多氯联苯衍生物。Sovol混合物的初始多氯联苯同源物转化率很高。所研究的反应可以用作通过热方法破坏有毒多氯联苯的预处理阶段。
