Testing and Balancing Fume Hood Systems
Published in Samuel C. Sugarman, Testing and Balancing HVAC Air and Water Systems, 2020
Titanium Tetrachloride (TiC14): Titanium tetrachloride is a chemical that generates white smoke. It is used to test the air pattern in laboratory fume hoods. Titanium tetrachloride is corrosive and irritating. It can stain the hood and will produce a residue that must be cleaned up. Care must be taken to minimize the effects on the hood. Also avoid skin contact or inhalation.

Minerals of base metals
Published in Francis P. Gudyanga, Minerals in Africa, 2020
Titanium oxide, TiO2, can be purified by converting it to titanium tetrachloride in a carbon thermal chlorination process [672,674] in which the ore is reduced with carbon, oxidised with chlorine to give titanium tetrachloride. The tetrachloride is then distilled and re-oxidised in a pure oxygen flame to give pure titanium dioxide with concurrent regeneration of chlorine.

One of the main precursors used in industrial processes for flame synthesis of TiO nanoparticles is titanium tetrachloride (TiCl). Pratsinis et al. [11] first described the oxidation of TiCl vapour between $700$ and C as a one-step chemical reaction: The reaction rate is first-order with respect to TiCl, and nearly zeroth-order for O up to a 10-fold oxygen excess. Accordingly, the titania nanoparticle nucleation rate can be written in the following form [11, 19]: where equals 1 if and 0 otherwise, is the TiCl number density, is the volume of a monomer, and is the one-step rate constant, which reads: with s and the activation energy. This rate has been the basis of many numerical studies of TiO nanoparticle formation [12, 19–22, 28, 39].

Alachlor (99.9%) was purchased from Sigma Aldrich Company (USA). Titanium tetrachloride (TiCl4, Sigma Aldrich) was used as a precursor to TiO2 and hydrochloric acid (HCl, Sigma Aldrich) was used as a solvent at the synthesis stage. Acetonitrile and ultra-pure water (High Performance Liquid Chromatography (HPLC) grade) were prepared form Sigma Aldrich Company and were used in chromatographic analysis. Other chemical products were purchased from Merck (Germany). A UV lamp, 125 w/m2, was used as the radiation source.
