A method for manufacturing an alkylated phenylnaphthylamine composition includes alkylating nonalkylated phenylnaphthylamine with olefin in the presence of clay catalyst without subsequent removal of nonalkylated phenylnaphthylamine and polyalkylated phenylnaphthylamine. Suitable nonalkylated phenylnaphthylamines include N-phenyl-1-naphthylamine, its derivatives, and mixtures thereof. The alkylated phenylnaphthylamine compositions can be used in antioxidant and lubricant compositions.
L'invention concerne un procédé de préparation de compositions de phénylnaphthylamines alkylées, consistant à effectuer l'alkylation des phénylnaphthylamines non alkylées avec une oléfine en présence d'un catalyseur d'argile, sans retrait ultérieur de phénylnaphthylamines non alkylées et de phénylnaphthylamines polyalkylées. Les phénylnaphthylamines non alkylées appropriées sont N-phényl-1-naphthylamine, leurs dérivés, et des mélanges de ceux-ci. On peut utiliser les compositions de phénylnaphthylamines alkylées dans des compositions antioxydantes et lubrifiantes.
