Moscow: Science, 1973. - 279 s. The monograph is devoted to the study of the role of solvents and phase state in radical-chain oxidation processes of organic compounds. For the first time collected and systematized material on the study of the role of the environment in the reactions of the origin, branching, continuation and breakage of chains. The influence of the environment on a number of radical reactions that occur with the participation of stable and alkyl radicals . is discussed. Knowing the influence of the medium on individual elementary reactions (including chain continuation and breakage), can predict the effect of the medium on the speed and direction of the oxidation process and thus control the process, increasing the yield of valuable oxygen-containing compounds and reducing the yield of by-products. The monograph is intended for researchers specializing in radical reactions and, in particular, reactions of oxidation of organic compounds. It is of interest to engineers and process engineers working in chemical plants and in technological laboratories dealing with oxidation processes.
