EPOXIDATION PROCESS INVOLVING IMPROVED-QUALITY HETEROGENEOUS CATALYTIC COMPOSITION Russian patent published in 2002 - IPC

Abstract RU 2181121 C2

FIELD: industrial organic synthesis. SUBSTANCE: titaniumcontaining catalytic composition is prepared by liquid-phase impregnation of silicon-containing solid with titanium halide, for instance with titanium tetrachloride, in hydrocarbon solvent followed by calcination. Further, catalyst is optionally brought into interaction with water and/or silylating agent. EFFECT: improved working characteristics of catalyst and increased yield of epoxy products. 34 cl, 3 tbl, 9 ex
