Environmental exposure to titanium tetrachloride is unlikely because it hydrolyzes rapidly upon contact with moist air to form a vapor of hydrochloric acid, titanium dioxide, and titanium oxychloride. 

Kotter et al. [79] prepared V and Ti-containing catalysts by dissolving appropriate amounts of ammonium vanadate in a titanium oxychloride solution followed by hydrolysis and evaporation. The 20 wt.-% V2O5 catalyst thus formed showed a decrease in BET specific surface area from 85 to 20 m g after heating the sample at 713 K for 100 h. 

Derivation Reaction of titanium oxychloride with acetylacetone and sodium carbonate. 

The study of To influence was carried out with the model of the chemisorption of TiCl4 by silica. It was shown in [44], that with the increase of To from 200 to 800°C the number of bonds forming titanium-oxychloride groups with surface increased (factor m grows) while titanium concentration in the samples decreases. Authors [44] associate the... 

The Erifon (U.S. Pat. 2570566) and Titanox (U.S. Pat. 2658000) processes depend upon padding with an acidified solution of antimony and titanium oxychlorides (Ward, J.S.D.C., 1955, 71, 569), and subsequently treating with a IS per cent sodium carbonate solution. A compound of the type shown below is formed ... 

Titanium tetrachloride (military designation, FM smoke) is a corrosive substance typically dispersed by spray or explosive munitions. A dense, white smoke results from the decomposition of FM smoke into hydrochloric acid, titanium oxychloride, and titanium dioxide. Because titanium tetrachloride is extremely irritating and corrosive in both liquid and smoke formulations, FM smoke is not commonly used. 

ETS-14 Penkvilksite like TiCls or titanium oxychloride Fumed silica No organic additive Hydrothermal decomposition of ETS-10 200 °C, 7 days Kuznicki, 1998 (38)... 

Importantly, this method was shown to be effective for many conventional McMurry reactions as well, and a catalytic variant, using commercially-available titanium powder, followed one year later." The catalytic reaction relied on an admixed chlorosilane, which both activated the commercial titanium powder by destroying the tightly bound oxide layer and regenerated, via ligand exchange, the active titanium chloride from the inactive titanium oxychloride product. 

All preparations start with an aqueous solution of titanium oxychloride (Kronos Titan 43 wt% calculated as TiCU). 

The volatile chlorides ate collected and the unreactedsohds and nonvolatile chlorides ate discarded. Titanium tetrachloride is separated from the other chlorides by double distillation (12). Vanadium oxychloride, VOCl, which has a boiling point close to TiCl, is separated by complexing with mineral oil, reducing with H2S to VOCI2, or complexing with copper. The TiCl is finally oxidized at 985°C to Ti02 and the chlorine gas is recycled (8,11) (see also... 

Titanous oxychloride forms yellow tablets, is inert in mineral acids and water and also stable in air. When heated in air, it gives titanium tetrachloride and titanium dioxide.
