Abstract
Titanium tetrachloride is a precursor of titanium dioxide, an important chemical for technological applications. TiCl4 is usually transformed into TiO2 via hightemperature gas-phase hydrolysis reactions (CVD process). Recently, aqueous-organic or pure oxygencontaining 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].
