Vanadous Chloride, vanadium trichloride, VC13.—This halide is obtained by the action of hydrogen chloride on finely divided vanadium at 300° to 400° C.,e or by heating vanadium tetrachloride to 140° C. in a current of carbon dioxide, which removes the chlorine formed at the same time. It can be conveniently made also by boiling vanadium oxy-trichloride, VOCl3, vanadium tetrachloride, VC14, or a mixture of both, with sulphur, under reflux. The reactions involved axe 7... 

Hypovanadic Chloride, vanadium tetrachloride, VC14, can be prepared synthetically from the lower chloride, VC13, by heating in a stream of chlorine at 600° C. Another convenient method consists in passing dry chlorine over ferrovanadium contained in a hard glass tube heated in a combustion furnace. The reaction is expressed ... 

What are the empirical formulas for the chlorides of vanadium containing 58.0%, 67.8%, and 73.6% chlorine Ans. VC12, VC13, VC14... 

Vanadium (IV) Chloride. Vanadium(IV) chloride (vanadium tetrachloride, VClJ is a red-brown liquid, is readily hydrolyzed, forms addition compounds with donor solvents such as pyridine, and is reduced by such molecules to trivalent vanadium compounds. Vanadium tetrachloride dissociates slowly at room temperature and rapidly at higher temperatures, yielding VC13 and Cl2. Decomposition also is induced catalytically and photochemically. This instability reflects the difficulty in storing and transporting it for industrial use. 

Vanadium (III) Chloride. Vanadium(III) chloride (vanadium trichloride, VQ3) is a pink-violet solid, is readily hydrolyzed, and is insoluble in nonpolar solvents but dissolves in donor solvents, eg, acetonitrile, to form coordination compounds. Chemical behavior of the tribromide (VBr3) is similar to that of VC13.
