Title:
AEROBIC CATALYSTS FOR ALCOHOL OXIDATION IN ORGANIC SOLVENTS AND IN SUPERCRITICAL CARBON DIOXIDE, PROCESS FOR THE PRODUCTION THEREOF AND THEIR USE IN OXIDATIVE CONVERSIONS
Document Type and Number:
WIPO Patent Application WO2005042155
Kind Code:
A3
Abstract:
Nanohybrid sol-gel materials, based on silica (ormosil) and doped with the ruthenium species tetra-n-propylammonium perruthenate (TPAP) are highly efficient catalysts for the selective oxidation of alcohols to carbonyls with oxygen at low pressure, in organic solvents as well as in carbon dioxide in supercritical state are decribed. Optimal conditions for the preparation and use thereof in liquid-phase as well as in supercritical CO2 were set by studying the structure-activity relationships of the materials, with particular reference to the surface hydrophobic/hydrophilic properties and to the textural ones.
