| abstract | Alkylmercaptophenols or alkylmercaptophenol ethers are produced by reacting a phenol or a phenol ether with an alkyl sulphenyl halide which is formed in the reaction mixture by reacting an alkyl disulphide or alkyl mercaptan with a halogen. The alkyl sulphenyl halide may contain 1-18, preferably 1-12, carbon atoms in the alkyl group. The reaction is preferably effected under anhydrous conditions with or without a solvent, e.g. carbon tetrachloride. An excess of phenol or phenol ether is preferably used. In a typical example, (I) p-hydroxyphenylmethyl sulphide is obtained by chlorinating a mixture of dimethyl disulphide and phenol in carbon tetrachloride at - 10 DEG to - 20 DEG C. Other examples describe the preparation of p-hydroxyphenyl butyl sulphide, p-hydroxyphenyl n-dodecyl sulphide, p - hydroxyphenyl - tert. - butyl sulphide and 2-hydroxynaphthyl-1 butyl sulphide. 1-Chloro-2-naphthol is obtained as a by-product in the preparation of 2-hydroxynaphthyl-1 butyl sulphide. Anisol is another specified phenol which may be treated. Reference has been directed by the Comptroller to Specification 875,464. |
