METHOD OF SEPARATING META-XYLENE FROM AROMATIC HYRDOCARBONS AND ADSORBENT FOR ITS REALISATION Russian patent published in 2013 - IPC C07C15/08 C07C7/13 B01J20/18 B01D15/08

Abstract RU 2490245 C2

FIELD: chemistry.

SUBSTANCE: invention relates to method of separating meta-xylene from mixture, which contains, at least, one other C₈ alkyl aromatic hydrocarbon. Method includes contact of mixture with adsorbent, which contains sodium zeolite Y with the average size of crystallites 50-700 nanometers, in conditions of adsorption.

EFFECT: invention provides effective method of separating meta-xylene from relatively contaminated mixture of C₈ alkyl aromatic hydrocarbons.
