 Abstract

Abstract of WO 9417021 (A1) The invention relates to an improvement in the practice of a catalyzed autoxidation of a starting material selected from (cyclo)alkanes, (cyclo)alkyl aromatics and alcohols derived therefrom. The improvement consists in the autoxidation being carried out by allowing oxygen to act on the employed starting material in the liquid phase, at elevated temperature and in the presence of a heterogeneous catalyst which is composed of a three-dimensional microporous structure, a so-called molecular sieve, containing aluminum, silicon and/or phosphorus oxides and a metal (Me) catalyst, incorporated into the lattice, which is selected from the transition metals from the groups 4 (Ti etc.), 5 (V etc.), 6 (Cr etc.), 7 (Mn etc.) and 8 (Fe etc.) of the Periodic System and the rare earths.; This catalyst, which involves substantially no loss in use, leads to the obtainment of a remarkably favorable selectivity, in particular in the preparation of ketones.
