Oxidation of Organic Substrates in Two-рhase Liquid Systems in the Presence of Tungsten Peroxo Complexes to Obtain Carboxylic Acids

The paper presents a brief review of the studies on the oxidation of various organic compounds with hydrogen peroxide performed by the authors at the Boreskov Institute of Catalysis SB RAS. Main catalytic systems for the production of carboxylic acids, which are the marketable products for industry and fine organic synthesis, under the conditions of interphase catalysis are considered. It was shown that the use of pre-synthesized catalytic complexes with the general formula Q3{PO4[WO(O2)2]4} improves the process performance, for example, increases the product yield, decreases the reaction time and lowers the catalyst concentration in comparison with the processes where the catalyst precursors are introduced in the reaction medium simultaneously with other reagents, and the active complex is formed in situ.

Liquid Phase Petroleum Resin Oxidation by Systems Based on Hydrogen Peroxide

The possibility of aromatic petroleum resin liquidphase oxidation was investigated. The influence of various factors on the modification process and properties oxidized samples was studied. The optimal parameters of the oxidation processes with hydrogen peroxide using interphase catalysis mechanisms, with peracetic acid, and with the electrogenerated oxidants complex of peroxide nature.
