Title:
EPOXIDATION PROCESS USING IMPROVED HETEROGENEOUS CATALYST COMPOSITION
Document Type and Number:
WIPO Patent Application WO1998050374
Kind Code:
A3
Abstract:
Highly active and selective epoxidation catalysts are prepared by combining silica or the like with a non-oxygenated hydrocarbon solution of titanium halide, removing solvent, calcining at an elevated temperature (preferably, in a substantially oxygen-free atmosphere), and, optionally, reacting with water and silylating. The resulting materials are useful heterogeneous catalysts for transforming olefins to epoxides using organic hydroperoxides.
