Titaniumchloridemin - Reference Information

, the process of refining and other processing to produce refined titanium tetrachloride is the main component of the titanium metallurgy process. Titanium-rich materials include rutile, titanium slag and synthetic rutile. The chlorination of the titanium-rich material produces a mixed furnace gas, and pure TiCl4 is obtained only after condensation and separation of the chlorination product of the titanium-rich material and refining of the crude titanium tetrachloride. TiCl4 is a raw material for the production of metallic titanium and titanium dioxide, can also be used as a smoking agent, and is also a raw material for the preparation of TiCl3 (catalyst for preparing polypropylene).
In the 50's of the 20th century, with the development of the production of titanium sponge and titanium dioxide by chlorination, the production of TiCl4 also reached industrial scale. In the early stage of chlorination of titanium-rich materials, titanium tetrachloride was produced by the shaft furnace chlorination method, and then the molten salt chlorination method and the fluidized chlorination method were developed to produce titanium tetrachloride.
Japan and the United States mainly adopt fluidized chlorination, and the Soviet Union has adopted molten salt chlorination since the early 60 s of the 20th century, while the shaft furnace chlorination method has been gradually eliminated, china titanium plant uses two methods: fluidized chlorination and molten salt chlorination. A comparison of the three main chlorination methods is listed in table 2. By the 80's, the world's large-scale chlorination furnace single furnace production capacity has reached 120 to 150 tTiCl4, the process has been relatively mature, equipment has been basically shaped.
The production process of refined titanium tetrachloride from titanium-rich materials is as follows:

The most important halide of titanium titanium tetrachloride is the most important halide of titanium, it is an important raw material for the production of titanium sponge and titanium white by chloride method. Pure titanium tetrachloride is colorless, transparent, dense and non-conductive liquid, with chemical formula TiCl4 and relative density of 1.726. The melting point was -25 °c and the boiling point was 136.4 °c. Irritating sour taste, easy hydrolysis, white smoke generated in the humid air. Soluble in water and decomposition, also soluble in alcohol, concentrated hydrochloric acid, and chloroform, carbon tetrachloride miscible. By titanium dioxide, carbon powder and sugar mixed into agglomerates, and after coking, more than 600 deg C into chlorine gas or chlorinating agent (such as carbon tetrachloride, etc.).
titanium tetrachloride is a raw material for producing metallic titanium and titanium compounds such as titanium dioxide and titanium trichloride. It is an important component of the ethylene polymerization catalyst, which is used as a smoke agent in the military and as a mordant in the dye industry. It is corrosive, and safety should be paid attention to during storage and transportation.
TiCl4 is non-flammable and non-explosive, but it is highly volatile and reacts intensely when in contact with water, forming a yellow precipitate with a large volume (hydrochloric acid and Ti(OH)) the compound represented by the molecular formula of nClx), and emits a large amount of heat; When exposed to the atmosphere, it reacts with moisture in the air to produce a strong irritating and corrosive HCl white smoke. Therefore, TiCl4 should be stored in a container with good air tightness.
pure TiCl4 hardly corrodes iron at room temperature, and crude TiCl4 or partially hydrolyzed TiCl4 will corrode iron when HCl is dissolved in it. TiCl4 dissolves a variety of gaseous, liquid, and solid impurities. TiCl4 can react with oxygen, magnesium, sodium and aluminum at a certain temperature, and the reaction is to produce titanium dioxide by chloride method, the basis for the production of titanium sponge by magnesium thermal reduction method and titanium sponge by sodium thermal reduction method and the preparation of TiCl3 by aluminum reduction method.
molecular structure the molecular structure of titanium tetrachloride is a tetragonal type, and the Ti atom is located in the center of the tetrahedron. It is a non-polar molecule. It is a covalent bond compound with good thermal stability. Partial decomposition at 2500K, decomposition of Ti and Cl2 at 5000K. Titanium tetrachloride is a reactive compound that reacts with many elements and compounds: with certain chlorides, a series of continuous mutual solubles can be formed (e. G., TiCl4-SiCl4,TiCl4-VOCl3, etc.); intense reaction with water to form a large volume of yellow precipitate and release a large amount of heat; Moisture absorption, white smoke, with irritating odor; Liquid TiCl4 and water interaction process is complex, Mr. hydrate, when the hydrate is hydrolyzed, the Cl atom is replaced by OH-to form a compound represented by the molecular formula of hydrochloric acid and Ti(OH)nClx; The reaction with boiling water can rapidly decompose to form metatitanic acid. The steam and steam hydrolysis at 300 ℃-400 ℃ to produce TiO2; Reaction with O2 in the air at high temperature to produce TiO2 and Ti2O3Cl2; Oxidation with O2 at higher than 550 ℃, tiO2 and Cl2 are formed at 1000 ℃, and can be reduced by H2 to TiCl3 at 500 ℃-700 ℃, it is reduced to TiCl2 at 650 ℃-850 ℃ and H2 excess, and reduced to metal Ti at 1000 ℃ and H2 excess; Does not react with C; And active metals Na, K, the reactions of Mg, Ca, Al and Fe were reduced to TiCl3, TiCl2 and Ti under different conditions, and the reactions of F2, HF, H2S, NH3 and Fe2O3 with red heat occurred; can rapidly absorb NH3 and release a lot of heat; Titanium tetrachloride and many fluxes can be completely miscible or reaction, soluble in dilute hydrochloric acid, alcohol and cold water, and bromine miscible and red; it reacts with many organic matters containing N and O and is yellow, red or brown. It is non-corrosive to Fe at room temperature and more corrosive than 200 ℃. There are many preparation methods, generally using Cl2 or other chlorinating agents (such as HCl, COCl2, SOCl2, CHCl3, CCl4, etc.) to chloride metal Ti and its compounds (such as TiO, TiN, TiC, TiS, titanate and other Ti-containing compounds). In industrial production, it is prepared by the method of titanium rich materials such as rutile chloride and high titanium slag. When the reducing agent is added, TiO2 is very easy to carry out the following reaction:(1)TiO2 C 2Cl2 = TiCl4 CO2 (2) tiO2 2C 2Cl2 = TiCl4 2CO.
toxicity titanium tetrachloride is highly toxic, has a strong stimulating effect, can cause local Burns, chemical conjunctivitis, keratitis, corneal opacity, can also cause upper respiratory tract inflammation and Pneumonia. Production of titanium metal, chlorine, hydrogen chloride, titanium tetrachloride and other harmful substances can also exist in the air, can stimulate the respiratory tract mucosa, causing serious lung damage. Long-term inhalation of titanium and its compounds dust can cause pneumoconiosis, is still inconclusive. The maximum allowable concentration of titanium tetrachloride (calculated by HCl in air) in the air of the workshop is 1mg/m3 (Su, 1972).
refined crude titanium tetrachloride the process of removing impurities from crude titanium tetrachloride and producing pure titanium tetrachloride, as the last important part of the titanium tetrachloride preparation process, the crude titanium tetrachloride is a light yellow or red-brown turbid liquid, containing many impurities, and the composition is very complex. Important impurities are SiCl4, AlCl3, FeCl3, FeCl2, VOCl3, TiOCl2, Cl2, HCl and so on. According to the difference between the impurity and the boiling point of TiCl4, it is divided into high boiling point impurity, low boiling point impurity and similar boiling point impurity. These impurities are harmful to the TiCl4 raw material used for the preparation of sponge titanium. If the crude TiCl4 liquid is used as the raw material, only the crude sponge titanium with the impurity content of 4 times the impurity content in the raw material can be prepared; for TiCl4 as a raw material for the production of pigmented titanium dioxide, VOCl3, VCl4, FeCl3, FeCl2, CrCl3, MnCl2, AlCl3, and some organic impurities cause the TiO2 to be colored. For the purification of crude TiCl with complex components, it is usually to find FeCl3 in high boiling point impurities, SiCl4 in low boiling point impurities and VOCl3 in similar boiling point impurities as key components respectively, the separation of a multi-component system is regarded as the separation of a four-component system from the key component SiCl4- TiCl4-VOCl3-FeCl3. The separation of key components is qualified, which indicates that the crude TiCl4 is qualified.
(1) physical method in addition to high boiling point and low boiling point impurities, according to their and TiCl4 boiling point or relative volatility of the characteristics of large difference, the use of distillation in addition to high boiling point substances, removal of low boiling point substances by distillation;
(2) chemical method in addition to vanadium impurities, vanadium impurities in crude TiCl4 is mainly VOCl3 and a small amount of VCl4, in addition to the purpose of vanadium is decolorization and oxygen removal. Cu in addition to V, H2S in addition to V, organic matter in addition to V. In addition to V is the separation of similar boiling point impurities. Generally, three sets of equipment are used to complete the separation process of the whole system, and the determination of the refining process scheme depends on the method of removing V. If Cu is used to remove V, V must be removed at the end; if H2S and organic matter are used to remove V, high boiling point and low boiling point impurities must be removed after V.
In the 50's of the 20th century, the production of refined titanium tetrachloride has reached industrial scale, and all countries in the world have adopted rectification method to remove SiCl4; Chemical method is used to remove vanadium, but the specific methods are not the same, japan and the United States use mineral oil method or H2S method, the former Soviet Union mainly uses aluminum method, China uses copper method.
