| titleOfInvention | Sulphurised phenols |
| abstract | The invention comprises sulphurized phenols prepared by heating sulphur with a phenol in the presence of a Friedel-Crafts catalyst. The compounds probably contain 2-5 phenol nuclei bridged by mono- or di-sulphide linkages predominantly in the o-position. Suitable phenols for use as starting materials are phenol itself, dihydroxybenzenes, naphthols, dihydroxybiphenyls and phenols containing aryl, aryloxy or aralkyl groups attached to the aromatic nucleus, e.g. a phenylphenol or a -methylbenzylphenol. Suitable catalysts are, for example, aluminium chloride, aluminium bromide, ferric chloride, zinc chloride and stannous bromide. Preferably 0.5 to 5 atomic proportions of sulphur are used to one molecular proportion of phenol.ALSO:Sulphurized phenols prepared by heating sulphur with a phenol in the presence of a Friedel-Crafts catalyst may be used as anti-oxidants in rubber. The sulphurized phenol may be incorporated into the rubber before or after vulcanizing and may be used for synthetic or natural rubber. Examples are given of the use of a sulphurized phenol as an natioxidant in a white rubber stock before vulcanizing and in a vulcanized rubber stock. |
