Anwendungen & Verwendung
Verwenden
As powerful reducing agent, Titanous chlorideb can reduces nitrate to ammonia; when boiled with aqueous SO2, sulfur is separated; hence is used as an aqueous solution for estimation of nitro groups, ferric ions, per-salts, etc. Removes stains, etc. (stripper) in laundering.
Herstellung & Synthese
synthetische
Titanium trichloride may be prepared by reducing titanium tetrachloride with hydrogen at 600°C. The tetrachloride may alternatively be reduced with aluminum, zinc, magnesium, tin, or by electrolysis.
