Abstract

Antioxidants for rubber are manufactured by condensing together an aminodiphenyl with an aromatic hydroxy compound, preferably a mono-hydroxy compound, with elimination of water. In an example, equimolecular proportions of p-aminodiphenyl and b -naphthol are heated together for 3 to 5 hours at 180-200 DEG C. In another example, p-aminodiphenyl and a slight excess over one molecular proportion of a -naphthol are heated for 3 to 4 hours at 200-240 DEG C. Tables show the antioxidant action of the products on rubber stocks vulcanized with the aid of diphenylguanidine as accelerator. Also specified are the reaction products of p-aminodiphenyl with phenol and with b -b -dioxydinaphthylmethane, and of o-amino-diphenyl with a -naphthol. Reference has been directed by the Comptroller to Specification 352,781.ALSO:As antioxidants for rubber are employed the products obtained by condensing an aminodiphenyl with an aromatic hydroxy compound, perferably a monohydroxy compound, with elimination of water. Tables show the action, on rubber stocks vulcanized with the aid of diphenylguanidine as accelerator, of the reaction products of p-aminodiphenyl with substantially one molecular proportion of b -naphthol and with a slight excess over one molecular proportion of a -naphthol. Also specified are the reaction products of p-aminodiphenyl with phenol and with b -b -dioxydinaphthylmethane, and of o-aminodiphenyl with a -naphthol. Reference has been directed by the Comptroller to Specification 352,781.
