- W22984608 abstract "Phenanthrene is one of the large-tonnage products of the coal-tar chemical industry. However, so far this hydrocarbon has no economically justified uses. The purpose of the present work was to study the liquid-phase oxidation of phenanthrene in presence of Co-Mn catalyst in o-dichlorobenzene (with additions of valeric acid). It is shown that oxidation of phenanthrene to phenanthrenequinone in presence of Co-Mn catalyst in o-dichlorobenzene and VA is possible in principle. The yield and formation rate of phenanthrenequinone are determined mainly by the composition of the solvent and the initial concentration of the hydrocarbon (phenanthrene). Study, by the method of active factorial experiments, of the influence of temperature, reaction time, and catalyst and phenanthrene concentrations on the principal process characteristics showed that the highest selectivity is reasched at (Cat) = 2x10/sup -2/ M and (RH) = 1.0 M. Under the chosen reaction conditions the reaction proceeds by a consecutive route, with phenanthrenequinone as the intermediate product. The reaction conditions for obtaining the maximum yield of phenanthrenequinone were found." @default.
