Abstract

A study was carried out of the processes occurring during chlorination of CuO and Cu 2O with chlorine or a mixture of CO and Cl 2 in a temperature range in which only solid products are formed. The reaction rate was studied at different temperatures and in the presence or absence of reductants, by the thermogravimetric method. It was shown that the reaction products have a pronounced blocking influence on further chlorination processes. The maximum degrees of conversion of CuO and Cu 2O are equal to 0.06 and 0.3 respectively. The sequence of formation of chlorination products, as found by X-ray analysis, was CuOCl 2, CuCl, CuCl 2 and CuO.
