Title: Titanium Trichloride
CAS Registry Number: 7705-07-9
Additional Names: Titanous chloride
Molecular Formula: Cl3Ti
Molecular Weight: 154.23
Percent Composition: Cl 68.96%, Ti 31.04%
Line Formula: TiCl3
Literature References: Prepn by reduction of the tetrachloride: Ingraham et al., Inorg. Synth. 6, 52 (1960); Sherfey, ibid. 57.
Properties: Dark red-violet, unstable, deliquesc crystals; dec on heating above 500°. The dry powder is pyrophoric in air. Very reactive and readily dissociated by moisture in air. Sol in water, exothermic process; sol in alcohol. Practically insol in ether. Keep tightly closed.
Use: A powerful reducing agent. Reduces nitrate to ammonia; when boiled with aq SO2, sulfur is separated; hence is used as an aq soln for estimation of nitro groups, ferric ions, per-salts, etc. Removes stains, etc. (stripper) in laundering. |
