Popis: 1. In copper-containing salt catalysts for oxidative chlorination on various carriers, catalysts with the same amount of applied salt component have a different surface composition as a result of the reaction with the carrier. The formation of surface melts is a function of the nature of the carrier and the concentration of the salt component. 2. “Separation” of the KCl·CuCl2 salt system with formation of surface states characteristic of KCl/carrier and CuCl2/carrier systems takes place on carriers with a developed surface. 3. Elimination of water molecules and hydroxyl groups from the surface of the carrier is significantly facilitated under the effect of the salt component. 4. Due to the reaction with the carrier, the salt component in the catalyst decomposes more easily than the individual salt system.
