C.I. 77864 - Nature
Open Data Verified Data
Colorless fuming liquid or colorless cubic crystals. Melting Point -33 °c. Boiling point 114.1 °c. The relative density of liquid was 226. Dissolve in cold water and release a lot of heat, soluble in ethanol, ether, benzene, toluene, carbon tetrachloride, carbon disulfide, etc. The foaming agent was burned immediately in case of H. Mixing with alkaline substances can cause explosion. It decomposes in case of hot water. In moist air, it absorbs water and generates trihydrate, giving off heat and hydrogen chloride gas, which is irritating and corrosive in the form of an approximate white smoke. Further water is added to produce compounds of different amounts of water of crystallization, such as 5, 8, and 9. Anhydrous tin chloride can absorb a large amount of chlorine at low temperature, while the volume of the formation of expansion and freezing point drop; Can react with ammonia to generate double salt; And alkali metal to generate Stannate. With alcohol, ether, aldehyde, ketone, carboxylic acid, Ester and other organic matter can be added reaction. Highly corrosive.

C.I. 77864 - Preparation Method
Open Data Verified Data
metallic tin chloride method: metallic tin is melted, and then cold water is poured to generate tin flowers, which are added to a reactor, and dried chlorine gas is introduced to carry out a reaction to produce tin tetrachloride. The product is yellow in color due to an excess of free chlorine. Can add a few tin flakes, heat distillation, dry with
The drying vessel receives a fraction of 105 N120 ° C. To prepare a finished anhydrous tin chloride product.
