1. Process for the production of a titanium silicalite shaped article by:

  • a) preparation of a synthesis gel containing a SiO2 source, a TiO2 source, a template compound and water, b) crystallisation 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) calcination of the green shaped article, characterised in that the template compound is chosen in a way that the titanium silicalite obtained by step b) exhibits MFI, MEL or BEA structure and the calcination step takes place after the formation of the green shaped article.
