The invention concerns a method for separating at least a benzothiophene compound from a hydrocarbon mixture, for instance gas oil, consisting in: (a) contacting said mixture or a fraction obtained therefrom, with a reagent comprising an acceptor complexing agent pi , to obtain a donor-acceptor complex between the acceptor complexing agent and said benzothiophene compound; (b) separating said complex from said mixture, or from said fraction, to obtain a fraction depleted or purified in said benzothiophene compound.
Procédé de séparation d'au moins un composé benzothiophénique d'un mélange d'hydrocarbures, par exemple le gas-oil, le contenant, dans lequel: (a) on met en contact ledit mélange ou une fraction obtenue à partir de ce dernier, avec un réactif comprenant un agent complexant accepteur .pi., pour obtenir un complexe donneur-accepteur entre l'agent complexant accepteur et ledit composé benzothiophénique; (b) on sépare ledit complexe dudit mélange, ou de ladite fraction, pour obtenir une fraction appauvrie ou épurée en ledit composé benzothiophénique.
