Abstract

A process for the production of a titanium silicalite shaped article by: a) preparation of a synthesis gel containing a Si2 source, a Ti2 source, a template compound and water, b) crystallization of the synthesis gel under hydrothermal conditions, c) drying of the titanium silicalite from step b) at a temperature below the decomposition temperature of the template compound, d) preparation of a formable mass containing the product from step c), a binder and a paste-forming agent, e) forming of the mass from step d) into a green shaped article, f) optionally drying, and g) calcinations of the green shaped article, as well as a titanium silicalite shaped article obtainable according to this process, and the use of this shaped article as a catalyst in epoxidation or ammoximation reactions.
