 Information @ a glance

Titanium oxychloride is formed in a reaction between titanium chloride (TiCl4) and water.

The mixture of tartaric acid and TiOCl2 solution forms a gel on heating on a water bath which decomposes at higher temperatures, > 423 K.

Mesoporous titania with an average pore diameter of 2.6 nm and pure rutile crystalline structural wall were prepared by hydrolysis of TiOCl2 aqueous solution at lower temperature by using octyl phenol polyethylene oxide as template-directing agent.

Yellow cakes of TiO(OH)2 were dissolved with added HCl solution to form a TiOCl2 solution.

The concentration of titanium in the as- preparedTiOCl2 solutionwas 5.27M, and this was used as a stock solution for synthesis of TiO2.

The precipitation from the aqueous TiOCl2 solution was not by the change of solubility but crystallization, in which crystalline TiO2 precipitates have been already formed at the stage of precipitation.

TiOCl2 acid solution hydrolyses N,N-dimethylformamide leading to the formation of dimethylammonium chloride and methanoic acid.

The inorganic polymerisation is gently controlled by the slow consumption of hydrochloric acid, and this one-pot process enables the preparation of novel titanium oxide-based nanoparticles in sols or gels.

Samples of titanium oxychloride solution stabilized in an acidic medium solution and N,N-dimethylformamide (DMF) were prepared in concentration of titanium between 0.05 and 0.7 mol/L-1 at room temperature, denoted TiDMF sol.

When mixing the titanium oxychloride and dimethylformamide solutions a double hydrolysis reaction takes place: DMF reacts with HCl to form dimethylammonium chloride and methanoic acid. At the same time, the consumption of HCl enables a gentle control over the inorganic polymerization.

Hydrolysis of DMF in TiOCl2 acidic medium leads to the formation of DMACl and HCOOH, and at the same time, the consumption of hydrochloric acid enables a gentle control over the inorganic polymerization.

TiOCl2 acid solution hydrolyzes N,N-dimethylformamide (DMF) at room temperature, leading to the formation of
