| titleOfInvention | METHOD OF OBTAINING NONYMMETRIC SULFIDES |
| abstract | The invention relates to organosulphuric substances, in particular the production of asymmetric sulfides of the total f-ly R-S-R, where R-CH; CH; CH; CH = CH-CH; CHCH; HO-CH-CH; CH-CH (OH) CH; R-CH; n-CFCH; 4-ClCH; 4-CH-CH; CF; CH; HO-CH-CH; 2-thienyl or 2-benzthiazolyl. The goal is to increase the yield of target substances and simplify the process. The latter is reacted with thiols with the corresponding halides (CHJ; CHBr; CHBr; CHBr; allyl bromide, ethylene chlorohydrin, benzyl chloride or 1,3-dichlorohydrin glycerol) in the presence of KOH in the medium of hydrazine hydrate. The molar ratio of thiol and KOH is 1: 1-2. These conditions simplify the process by eliminating heat and toxic solvent and facilitating the release of target substances, the output of which increases from 30-84 to 60-95%. 1 hp f-ly. |
