Abstract
The disposal and recycling of chlorohydrocarbons waste from organic synthesis which is annually produced at least 1,5 million tons is one of the global problems and is under the great UN's attention. Organochlorine residues are xenobiotics and adversely affect the environment. Thermodynamic modeling of interactions in the systems ZnO-CHxCly (x + y= 4)-O2 for determination of the theoretical content of chlorohydrocarbons as chlorinating agents for extracting nonferrous metals from very concentrated ore is presented in this article. The studies were conducted using the "Astra" software based on the principle of maximum entropy. Infobase of the "Astra" complex contains information on 5547 compounds, 79 items codified in the National Bureau of Standards and the Joint Institute for High Temperatures, Russian Academy of Sciences.
