Abstract

An experimental study on obtaining concentrates of organic compounds from fuel fractions of petroleum by complexation with metal halides: aluminum chloride, aluminum bromide, anhydrous zinc chloride, and its crystal hydrate has been performed. Optimal conditions have been selected for the complexation reaction of aluminum and zinc halides with electron-donor compounds of diesel and jet fuels. The degree of removal of organic sulfur compounds from the diesel or jet fuel by complexation with aluminum chloride reaches 79.6 or 10.0 rel. %, respectively. It has been found that the concentrates obtained contain a large amount of normal and weakly branched alkanes, which form clathrates with polar components of the donor–acceptor complex (DAC). A mechanism is proposed for the intermolecular interaction of alkanes with the DAC components by hydrogen bonding with halogen, oxygen, and sulfur atoms.
