THE INFLUENCE OF SURFACE-ACTIVE SUBSTANCES ON THE OXIDATION OF ETHYLBENZOL, CATALYSIS OF ETHYLBENZOL OXIDATION BY CETYLTRIMETHYLAMMONIA OF BROMIDE IN COMBINATION WITH ACETYLACETANATE OF COBALT
There have been studied kinetic objective laws of ethylbenzol oxidation (RH) and decomposition of a-phenylethyl of hydroperoxide (ROOH) in the presence of cationic surface-active substance-cetyltrimethylammonia of bromide (CTAB) and bis-(chacetylacetonate) of cobalt (Co(acac)2). The combination of Co(acac)2 (0,1 mM) with CTAB (1mM) is a hidheffective synergetic catalytic system: the oxidation of RH at 600C is characterized by a high rate of absorption O2 and low stationar concentration of ROOH, the main product of oxidation RH in this system is acetophenon. The effective energy of activization the decomposition of ROOH is Eeff=45,5 kJ/mol, the outlet of radicals-e=0,09. It has been made a supposition that at the oxidation of ethylbenzol by the oxygen from the air, the mecanism of cobalt-bromide catalysis is realized in the system CTAB-Co(acac)2; the concentration of reagents (ROOH, Co(II), Br) in microagregates CTAB at a small brutto concentrations of the catalysator brings to the rise of the rate of ROOH decomposition and to the fall of the radicals outlet into volume of oxidating
