Chlorinated tin is a liquid with no color, and the gas molecules are tetrahedral. Bond length of Sn - Cl 228 PM. - 33 ℃, melting point, boiling point 114.1 ℃. The density is 2.226 grams per centimeter cubed. It can be soluble in water, soluble in gasoline, carbon disulfide, turpentine and other organic solvents. Slowly add water to produce the colloid of SnO 2 and the hexachloric acid [h2 [SnCl 6]]. When wet air is encountered, the formation of stannic acid and hydrogen chloride is produced by hydrolysis, and the white smoke is corrosive. The amount of water formed by the amount of water formed by the amount of water was made up of five water and four chlorinated tin. It is used as a catalyst for chlorination of media and organic synthesis, and is used for tin plating.
Tin chloride as one of the typical block of solid acid catalyst, alcohol in the acid vinegar, acetal and ketal, dehydration, dienes, heterocyclic synthesis reaction of synthesis has the certain catalysis. In the study of people, tetrachloride is widely used in the esterification of acid and is very repetitive, so there is a better application prospect. Further research is needed in the reaction of acetal, acetone, dehydration, diene synthesis, heterocyclic synthesis, and therefore has great research space.
