Abstract

1479263 Preparation of styrenated diphenylamine GOODYEAR TIRE & RUBBER CO 9 April 1976 [18 April 1975] 14628/76 Heading C2C The invention comprises a process for preparing styrenated diphenylamine (α-methylbenzylated diphenylamine) containing a substantial amount of p-substituted diphenylamine by reacting a mixture of diphenylamine and styrene in the presence of a catalytic amount of an activated acid clay catalyst containing a major amount of aluminium hydrosilicate at a temperature of 170-300‹ C. and using a molar ratio of styrene to diphenylamine of 1 to 2.5 : 1.
