METHOD OF REGENERATING BASIC ANIONITE CATALYSTS Russian patent published in 2008 - IPC B01J31/40 B01J31/08 B01J49/00 B01J47/00

Abstract RU 2322295 C1

FIELD: industrial organic synthesis catalysts.

SUBSTANCE: invention relates to regeneration of basic anionite catalysts for process of production of alkylene glycols via hydration of corresponding alkylene oxides. Method according to invention consists in treatment of spent catalyst with aqueous solution of inorganic salts of iodine and inorganic acids or with hydroiodic acid aqueous solution.

EFFECT: achieved complete restoration of initial volume and selectivity of catalyst and thereby prolonged lifetime of expensive anionite catalyst.
