Interaction of Titanium(IV) Chloride with Selected Ethers and Ketones

摘要

Titanium tetrachloride is a precursor of titanium dioxide, an important chemical for technological applications. TiCl4 is usually transformed into TiO2 via high-temperature gas-phase hydrolysis reactions (CVD process). Recently, aqueous-organic or pure oxygen-containing organic solvents (ethers or ketones) have been used in TiO2 synthesis instead of water [1, 2]. In such systems, TiCl4 acts as Lewis acid to form various complexes with the oxygen-containing donors [3]. The complexes vaporization is affected by the crystal structure type and the bonds energy [4].
