INFLUENCE OF REACTION MEDIUM OF CHEMICAL NATURE OF CARBON CATALYST SURFACE IN PROCESSES OF ESTERIFICATION, HYDROLYSIS OF ETHERS AND DECOMPOSITION OF HYDROGEN-PEROXIDE

The state of surface of hydrogen and some cation substituted forms of oxidized carbons (OC) before and after catalysis in liquid and gaseous phase reactions of synthesis of butyl acetate ether, hydrolysis ethyl acetate ether and reaction of decomposition of aqueous hydrogen perox ide was investigated by infra-red spectroscopy and chemical analysis. Together with basic processes on carbon surface, surface reactions bet ween functional groups and adsorbing reagent (esterification) or with reaction products (hydrolysis) may proceed or new functional groups at oxidition-reduction process of H2O2 decomposition may appear. It was shown that the largest changes of chemical nature of the surface (toge ther with primary drop of catalytic activity (CA) up to establishment of the stationary state) occur on H-form of OC in comparison with cati onsubstituted forms of carbon. It was found that the chemical nature o f ionic forms of OC does not practically change, higher CA is observed , that makes this forms of OC more perspective catalysts for the studi ed processes.
