Abstract

4-Alkylmercaptophenols are prepared by reacting phenol, or a substituted phenol having a free 4-position, with a dialkyl disulphide in the presence of a phosphoric acid catalyst. Specified phenols which may be treated are phenol, m-cresol, 3-ethyl-and-3-isopropyl-phenol, 2-tertbutylphenol, 3-methyl-6-isopropylphenol, 3, 5-diisopropylphenol, 2, 6-diisopropylphenol, 2-methyl-5-isopropylphenol, 3, 5-dimethylphenol, 2-phenylphenol, 3-chlorophenol and 2-methoxyphenol. Specified dialkyl disulphides are dimethyl, diethyl, di-n-and di-iso-propyl, di-n-and di-iso-butyl di-n-and di-iso-amyl and di (chloromethyl) disulphides. The catalyst may be ortho-, meta-, pyro- or poly-phosphoric acid. The reaction may be effected under reflux, and the catalyst may be separated from the product and re-used. The alkylmercaptans obtained as by-products may be used as such or oxidized to the corresponding disulphides. Examples are given in which phenol and m-cresol are treated with dimethyl disulphide, minor proportions of 2-methylmercaptophenol being also obtained when phenol is treated.
