(FR) ALKYLATION DIRECTE D’UNE N-ALKYL-N’-PHENYL-P-PHENYLENEDIAMINE
Abstract: front page image
(EN)A single-step process is disclosed for the ring alkylation of at least one N-alkyl-N'-phenyl-phenylenediamine with at least one olefin wherein the process comprises heating a mixture of the N-alkyl-N'-phenyl-phenylenediamine(s) and olefin(s) in the presence of a catalytic amount of at least one alkyl aluminum halide at a temperature of from about 50 to about 350 °C in a sealed vessel for from about one to about 30 hours.
(FR)La présente invention concerne un procédé en une étape destiné à l’alkylation d’un cycle d’au moins une N-alkyl-N’-phényl-phénylènediamine avec au moins une oléfine, le procédé comprenant le chauffage d’un mélange de la ou des N-alkyl-N’-phényl-phénylènediamines et de la ou des oléfines en présence d'une quantité catalytique d’au moins un halogénure d’alkylaluminium à une température allant d’environ 50 °C à environ 350 °C dans un récipient étanche sur une période d’environ une à environ 30 heures.
