titanium(+2) cation trichloride - Nature
Open Data Verified Data
dark purple deliquescent crystals. d 2. 64. Decomposition above 440 °c. Soluble in ethanol, chloroform-soluble, insoluble in ether and benzene. Has a strong reducing effect. Oxidation reactions can occur when exposed to air. Does not burn, but can cause combustion in the presence of an oxidant. By high thermal decomposition to produce toxic corrosive gases. In the presence of moist air, heat and an irritant corrosive hydrogen chloride gas are released in the form of an approximate white smoke.

| Chemical reaction | The Nature of titanium trichloride is active, can react with a variety of elements or compounds: thermal Oxidation in O2 gas sometimes combustion to produce TiCl4 and TiO2; Reduction to TiCl2 in H2 gas flow; Reaction with water vapor at 600 ℃ to produce TiOCl and HCl; Deliquescence in air, soluble in water, alcohol and acid, in acidic solution gradually oxidized by O2 in the air, but also by Fe3, Cr2O72-and VO3-and other oxidants oxidation; tiCl4 is formed by reaction with HCl at high temperature; TiOCl is formed by interaction with Fe2O3, TiO2 and SiO2 at 600 ° C.; It can be reduced to metal Ti by alkali metal or alkaline earth metal under heating. It is an unstable chloride, dissociates at high temperature, and disproportionation reaction occurs to form TiCl2 and ticl4. Anhydrous titanium trichloride (TiCl3) can be prepared by reducing TiCl4 with H2, Na, Mg, Al and Ti as reducing agents under appropriate conditions. An aqueous solution of titanium trichloride can be prepared by dissolving metal Ti in hydrochloric acid under an atmosphere of H2 or an inert gas. This information was edited by chemical book Xiaonan (2015-08-22). |
| four crystal forms of titanium trichloride | titanium trichloride has four crystal forms and one hexahydrate: (1) tiCl4 was reduced at high temperature to obtain a-type TiCl3, purple plate-like structure, belonging to hexagonal system, lattice constant a = 6.122 × 10-8cm,c = 17.52 × 10-8cm. The relative density was 2.64. 440 degrees C decomposition. Boiling point 660 °c (14.132 X 103Pa). (2) reduction of TiCl4 by alkyl aluminum to obtain β-type TiCl3, brown powder, fibrous structure. Transition to the α-form at 250-300 °c in an inert gas stream. (3) reduction of TiCl4 by aluminum to obtain γ-type TiCl3, red-purple lamellar crystals. (4) the γ-type TiCl3 is ground to obtain δ-type TiCl3, which is a purple powder with unknown structure and has higher catalytic performance than other crystalline ticl3. Melting point 730 ℃-920 ℃, relative density 2.69, boiling point 660 ℃(106 × 133.322). Soluble in water and ethanol-soluble purple, heating solution becomes blue, cold and then return to purple. After long-term storage in the air, it discolored and precipitated metatitanic acid (H2TiO3). Insoluble in ether. Titanium trichloride is a catalyst for many organic chemical reactions and is widely used as a primary catalyst for the production of polypropylene. Used as an azo dye analysis titration solution, and for the Colorimetric Determination of Cu, Fe and V. In addition to four different crystal forms, titanium trichloride also has a Hexahydrate (TiCl3 · 6H2O), which is divided into purple stable and green unstable due to different coordination of ligands. The disproportionation reaction occurred above 450 ° C. To produce titanium dichloride and titanium tetrachloride. Insoluble in benzene, slightly soluble in chloroform, soluble in ethanol. The hexahydrate is a pale purple crystal. Easy to absorb moisture. Soluble in water. It is slowly oxidized and decolorized in dry air. It is rapidly converted to the hydrate of titanium dichloride in moist air. |
| purpose | is mainly used as a strong reducing agent. Catalysts for the polymerization of A- olefins. For azo dye analysis. titrant and strong reducing agent for azo dye analysis |
| production method | the aluminum reduction method uses an excess of titanium tetrachloride to react with aluminum powder at 136 °c, aluminum trichloride is used as an initiator to generate titanium trichloride and aluminum trichloride. The excessive amount of titanium tetrachloride is distilled off by heating and recovered for recycling. At the same time, the aluminum trichloride is sublimed to obtain the finished titanium trichloride. Its 3TiCl4 Al → 3TiCl3 A1C13 |
