| titleOfInvention | Method of obtaining alkyl(aryl)polysulfides |
| abstract | The invention relates to alkyl (aryl) polysulfides, in particular compounds of the general formula: (R) (S), where R is lower alkyl, benzyl, phenethyl, or 3, which, as vulcanization accelerators and antioxidants of rubber or hydrocarbons, are used in polymeric or hydrocarbon production. - simplification of the process for the release of target events. The process is conducted from sulfur and alkali in the presence of a reducing agent — hydrazine hydrate, at a molar ratio of 1: 1 ... I, 5: 0.25 ,,, I, in one medium at 80., 90 ° C. Then, the obtained product is treated with an appropriate alkyl halide (C1, Br, I) with heating, better at 50, .. 00 C. The method allows to exclude the formation of monosulfide, as well as polysulfides (p 3) and to obtain the total yield of di- and trialkyl (aryl sulfides to 80,., 95% in conditions that ensure simple separation of the target product - cooling and evaporation of the separated organic phase, h, pfl.
