FIELD: chemistry.
SUBSTANCE: invention relates to a method of adsorptive separation of one compound from a mixture of C8 aromatic hydrocarbons, namely from para-xylol. The method of separating para-xylol from the mixture of an initial raw material includes bringing liquid, which contains an undesirable isomer, in contact with a layer of adsorbent, which includes crystals of a metal-organic framework, selected from the group, consisting of Al-MIL-53, Zn-MOF-5 and their mixtures, and extraction of para-xylol from the adsorbent. The said crystals of the metal-organic framework adsorb para-xylol and make it possible for meta-xylol, ortho-xylol and ethylbenzene to pass through the said crystals of the metal-organic framework without adsorption.
EFFECT: method provides separation of para-xylol from other C8 aromatic hydrocarbons.
