Titanosilicate

A titanosilicate is a silicate mineral where some portion of the silicon atoms have been replaced by titanium(IV) atoms. The term most commonly refers to the zeolitic polymorph, also called titanium silicalite, which is a heterogeneous catalyst in industrial chemistry.

Applications

Titanosilicate catalysts are commonly used in oxidation reactions that employ hydrogen peroxide as an oxidant. The production of propylene oxide by epoxidation of propylene is a major industrial application.

Synthesis

Titanosilicates can be prepared via crystallisation of silica and titanium dioxide with quaternary ammonium cations as a structure-directing agent. The silica and titanium dioxide are provided by hydrolysis of tetraethyl orthosilicate and tetrabutyl orthotitanate.
