Stability | Stable, but reacts violently with water and is spontaneously flammable in air. |
Sensitive | Air Sensitive |
Physical and Chemical Properties | Dark purple crystals. The relative density was 2.64. Unstable. Melting point 440 °c, boiling point 660 °c. Soluble in ethanol, hydrochloric acid, insoluble in ether and benzene. It has strong reducibility, and immediately decomposes in water and air to generate hydrogen chloride and titanium oxides, hydroxides and oxychlorides. Dry powder in the air flow kinetic energy spontaneous combustion. |
Use | Used as titration solution and strong reducing agent for azo dye analysis |

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.
an excess amount of titanium tetrachloride was used to react with aluminum powder.
A complex catalyst system consisting of a Natta-type catalyst with triethylaluminum or with chlorodiethylaluminum is used for the polymerization of propylene.
It has strong irritation to mucosa, upper respiratory tract, eyes and skin. Staff should be protected. If the skin and eyes are touched, they should be immediately rinsed with plenty of flowing water. Should be stored separately from the oxidant, alkali, H foaming agent. Keep away from fire and heat source. Should be sealed, not with air contact, should not be large or long-term storage.
