Abstract
Thermal stability and gas phase composition of the most common technical mixtures of polychlorinated biphenyls “Sovol” and “Trichlorobiphenyl” were studied by simultaneous thermal analysis and mass spectrometry compared to their derivatives synthesized by the interaction of these mixtures with sodium methoxide in dimethyl sulfoxide and methanol. For the first time it was established that derivatives of polychlorinated biphenyls are less thermostable compounds as compared with the initial products and under pyrolysis they undergo not only evaporation stages, but also decomposition processes to the simplest volatile substances. Thermal destruction of derivatives is characterized by a decrease in the level of emission of hazardous compounds and requires less energy.
