A new approach to the problem of processing of the saturated hydrocarbons and hydrogen sulfide that is contained in oil and gas condensate is considered in this article. At the present time the methods of synthesis of alkane- and cycloalkanes applied difficult and expensive. The hard conditions: temperature above 650 К and in the range 170-220 К, ultraviolet irradiation, chemical agents (complexes of halogened of metals of Al, Со(II), Ni(II) or аlkilchlorides) are used for initiation of homolysis of С-Н bond in the saturated hydrocarbons. The modern way to synthesis of the derivative saturated hydrocarbons in soft conditions is based on application of Lewis and Brensted superacids or redox and catalysts from metal’s complexes. The method of synthesis of practically useful cyclic and aliphatic thiols, which we are offered in this work, is based on the electrochemical oxidizing activation of the hydrogen sulfide at room temperature and atmospheric pressure. The reaction of thiolation of alkanes and cycloalkanes with participation the hydrogen sulfide flows on a radical mechanism. The exit of basic (thiols) and secondary (sulfides, disulfides) reaction products depend on the structure of original hydrocarbons - size of cycle, nature and position of substitute.
