Title (EN) SELECTIVE DIETHYLATION OF NAPHTHALENE TO 2,6-DIETHYLNAPHTHALENE
(FR) DIETHYLATION SELECTIVE DE NAPHTALENE EN 2,6-DIETHYLNAPHTALENE
Abstract:
(EN) The selective alkylation of naphthalene or 2-ethylnaphthalene to diethylnaphthalene while maximizing the yield of the 2,6-diethylnaphthalene isomer is achieved by carrying out the reaction in the presence of a shape selective catalyst such as the zeolite catalyst ZSM-12.
(FR) On obtient l'alkylation sélective de naphtalène ou de 2-éthylnaphtalène en diéthylnaphtalène, tout en maximisant le rendement de l'isomère de 2,6-diéthylnaphtalène, en procédant à la réaction en présence d'un catalyseur à sélectivité de forme tel que le catalyseur à zéolite ZSM-12.
