Abstract
A method for separating at least a benzothiophene compound from a hydrocarbon mixture is disclosed. The method includes contacting the mixture of a fraction obtained therefrom with a reagent including an acceptor complexing agent π, to obtain a donor-acceptor complex between the acceptor complexing agent and the benzothiophene compound; and separating the complex from the mixture, or from the fraction, to obtain a fraction depleted or purified in the benzothiophene compound.
Claims21
A process for the separation of at least one dibenzothiophene compound from a mixture of hydrocarbons, wherein said mixture or a fraction obtained from the mixture is brought into contact with a reagent comprising a π-acceptor complexing agent, in order to obtain a donor-acceptor complex between the acceptor complexing agent and said dibenzothiophene compound;
- said complex being separated from said mixture or from said fraction, in order to obtain a fraction impoverished in or purified from said dibenzothiophene compound.
