Article is devoted to the research of the influence of the sodium salt of perfluoro sulfonic  acid, as a stabilizer, on the catalytic activity of iron chloride and sodium chloride in the reaction of direct chlorination of ethylene to 1,2- dychloroethane. During research authors found that increase of stabilizer concentration up to 4% mas. had no significant impact on the catalytic activity of the complex but increase from 4% mas. up to 10% mas. allowed to shorten time of dissolution of sodium chloride and to reach needed concentration of sodium ions in the reactor of direct chlorination. With research stabilizer concentration the purity of the formed dichloroethane increases and the amount of by-product - trichloroethane decreases.
