METHOD OF SYNTHESIS OF ALKYLENE GLYCOLS Russian patent published in 2000 - IPC

Abstract RU 2149864 C1

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention relates to catalytic methods of synthesis of alkylene glycols. Process of synthesis of alkylene glycols by hydration of alkylene oxides is carried out in the presence of catalytic system based on nitrogen-containing ion-exchange polymeric substances. The latter have nitrogen atoms as electropositive centers coordinated with anions being two or more electro-positive centers are coordinated with the same anion of di- and/or tri- and/or polybasic acids. EFFECT: increased specific output of process. 11 cl, 1 tbl, 20 dwg, 31 ex
