Introduction | anhydrous stannic tetrachloride is a colorless and easily flowing liquid with a regular tetrahedral configuration of gas molecules. Bond length Sn-Cl 228pm, melting point -33 °c, boiling point 114.1 °c. The density was 2.226g/cm3. With carbon tetrachloride, ethanol, benzene miscible, soluble in water, soluble in gasoline, carbon disulfide, turpentine and other organic solvents. |
Application | tin tetrachloride can be used as a raw material for the synthesis of organotin compounds, as a mordant for dyeing, manufacturing blue paper and photosensitive paper, lubricating Oil additive; Glass surface treatment to form a conductive coating and improve wear resistance. It can be used as a cationic polymerization catalyst for isobutylene, α-methylstyrene and the like; It can also be used for the production of organotin compounds, and it can be used as an analytical reagent and an organic synthetic dehydrating agent. |
preparation | tin tetrachloride can be obtained by introducing an excess of chlorine into a stannous chloride solution. |
toxicity | inhalation of tin dust can cause chronic bronchitis. The maximum allowable concentration in air is 2mg/m3 (calculated as metallic tin) for inorganic compounds of tin in the United States. Production personnel should wear work clothes, protective glasses, anti-virus masks, latex gloves and other labor protection articles, and pay attention to the protection of respiratory organs and skin. Production equipment should be closed and the workshop should be well ventilated. |
Use | tin tetrachloride is an intermediate in the synthesis of the acaricide tricyclic tin, Styrene tin and triazole tin. raw materials for synthesis of organotin compounds, mordant for dyeing, manufacture of blue paper and photosensitive paper, lubricant additives, glass surface treatment to form conductive coatings and improve abrasion resistance. It is used as a cationic polymerization catalyst for isobutylene, α-methylstyrene, etc. used as an analytical reagent and mordant, and also used in organic synthesis used as a spectral purity and high purity reagent used in the production of organotin compounds, and used as analytical reagents and organic synthesis dehydrating agents. Also used in the electroplating industry in small quantities for the separation of potassium from rubidium and cesium. Organic analysis was used for saponification of phenols and ethers. Dehydrating agents for organic synthesis. The manufacture of organotin. Fabric dyeing. |
production method | metallic tin chloride method metallic tin is melted, and then poured into cold water, excited into tin flowers, added to the reactor, the reaction was carried out by introducing dry chlorine gas, and tin tetrachloride was produced. The product is yellow in color due to an excess of free chlorine. Several tin flakes can be added, heated and distilled, and the fraction of 105 to 120 ° C. Is received in a dry container to obtain a finished anhydrous tin chloride product. Its Sn 2C12 → SnCl4 tin tetrachloride is made of tin and chlorine as raw materials. |
