Abstract
The invention relates to a catalyst obtained by deposition of a zeolite of TS-1 type on an inert honeycomb-shaped support which can be used in liquid-phase reactions for the epoxidation of olefins under the action of hydrogen peroxide.
Claims9
An epoxidation catalyst comprising a zeolite containing titanium in the framework deposited on a honeycomb-shaped support by impregnation with the aid of a binder.
A process for the manufacture of an epoxidation catalyst comprising a zeolite containing titanium in the framework deposited on a honeycomb-shaped support by impregnation with the aid of a binder, according to which, in a first stage, the titanium containing zeolite is dispersed in the binder and, in a second stage, the dispersion thus obtained is deposited on a honeycomb-shaped support.
Process for the manufacture of epoxides, preferably epichlorohydrin or propylene oxide, by reaction between an olefin, preferably allyl chloride or propylene, and a peroxide compound, preferably hydrogen peroxide, in the presence of a catalyst comprising a zeolite containing titanium in the framework deposited on a honeycomb-shaped support by impregnation with the aid of a binder.
