Uses & manufacturing

UsesUsed as a reducing agent (nitrate to ammonia), laundry stain remover, and analytical reagent; [Merck Index]

General Manufacturing InformationTitanium chloride (TiCl3): ACTIVE

Applications · 4 items

UsesIt is mainly used as a strong reducing agent; as the catalyst of Α-olefin polymerization. It can be used for azo dye analysis. It can be used as the titrant of azo dye analysis and strong reducing agent.

UsesTitanium Chloride (≥12% HCl Solution) is ued in the optimized gas chromatography tandem mass spectrometry for 1,1''-sulfonylbis[2-(methylthio)ethane] quantification in human urine

UsesAs 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.

General DescriptionA dark violet crystalline solid. Denser than water. Contact may burn skin, eyes, and mucous membranes. May be toxic by ingestion, inhalation and skin absorption. Used to make other chemicals.

Preparation methods · 2 items

PreparationAluminum reduction process: apply an excess of titanium tetrachloride to react with aluminum powder at 136 °C with aluminum chloride being taken as the initiator to produce titanium trichloride and aluminum trichloride. Heat and steam out excess amount titanium tetrachloride for recycling usage. Meanwhile, the aluminum trichloride undergoes sublimation to get finished product of titanium trichloride. Its reaction equation is: 3TiCl4 + Al → 3TiCl3 + A1C13

PreparationTitanium 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.
