Basic Info
Model No.: SY-7646-78-8
Product Description
Tin Tetrachloride With Cas 7646-78-8
Anhydrous tin tetrachloride is a colorless liquid that flows easily. Key length Sn - Cl 228pm. - 33 ℃, melting point, boiling point 114.1 ℃. The density is 2.226g/cm cubed. It can be mixed with carbon tetrachloride, ethanol and benzene, soluble in water, soluble in most organic solvents such as gasoline, carbon disulfide and turpentine oil. Slowly add water to create SnO colloids and HCL solution. In the case of moist air, hydrolysis from the formation of stannic acid and hydrogen chloride, white smoke, corrosive. And the calculated amount of water formed pentahydrate tin tetrachloride. Used as a chlorination catalyst for mordant and organic synthesis and for tin plating.

Use
It is the raw material for the preparation of organotin compounds, the dyeing mordant and the shrinkage mixture. [1]
It is used as catalyst for cationic polymerization of isobutene and post-methyl styrene. [3]
Manufacturing blue sun paper and sensitive paper, lubricating oil additives, glass surface treatment to form conductive coating and improve wear resistance. [3]
Used as chlorination catalyst and sugar bleaching agent in organic synthesis. It can also be used for conductive coatings and tin plating.
The vapors of tin chloride are mixed with ammonia and water vapor to form particles of tin hydroxide and ammonium chloride in the form of smoke, which is used for making smoke curtain projectiles in military. Reaction formula: SnCl4+4NH3+4H2O goes to Sn(OH)4+4NH4Cl.
For making FTO conductive glass, FTO glass can serve as a replacement for ITO conductive glass products, widely used in liquid crystal display, photocatalysis, thin film solar cells, basement, etc., the market demand is great. The equation is SnCl4+2H2O=SnO2+4HCl.
Used as analytical reagent, organic synthesis dewatering agent. Also used in electroplating industry. [3]
Alkyd esterification reaction: with traditional acid alcohol acetify response is a production process of concentrated sulfuric acid as catalyst preparation, the characteristics of long production cycle, by-products, equipment corrosion is serious, the post-processing complex reaction, waste acid disadvantages such as environmental pollution, so people have been committed to the research of new type catalysts, in order to simplify the production process, reduce production cost, stannic chloride as an efficient catalyst, vinegar is a cheap chemical products, therefore, arouse people's attention, the research in this aspect are also increasing. Stannic chloride to replace the traditional sulfuric acid catalyst as a catalyst, vinegar in acid alcohol vinegar, most research studies involving anhydrous stannic chloride or of stannic chloride pentahydrate, catalytic acetify, chloroacetic acid and alcohol vinegar, the solid carrier catalysis vinegar in the form of [2]
Ketodene reaction: the cyclohexanone glycol was synthesized by using sncl4.5h2o as catalyst from cyclohexanone and ethylene glycol.
Acetal reaction
Dienes synthesis
The dehydration reaction using SnCl4.5H2O as catalyst has not been studied much, and further studies are still needed.
Tin tetrachloride, as one of the typical solid acid catalysts, has certain catalytic effects in acid-alcohol vinegar, acetaldehyde, ketone, dehydration, diene synthesis and heterocyclic synthesis. It can be seen from people's research that tin tetrachloride has wide application and good repeatability in esterification of acid alcohol, so it has a good application prospect. Further studies have yet to be carried out on the reactions of aldehydes, ketones, dehydration, diene synthesis and heterocyclic synthesis. [1]
