Tin two-chloride represents white crystal powder, we will dissolve in water, alcohol, air, acetone. Melts and boils without decomposition. On air it is gradually hydrolyzed by moisture and is oxidized. SnCl2 crystalline hydrate • 2H2O - "tin salt". Reacts with alkalis, hydrate of ammonia. Strong reducer, weak oxidizer.
Density: 2,71 g/cm ³. Temperature of melting is 247 °C (crystalline hydrate 37,7 °C), temperature of boiling is 652 °C.Chemical formula: SnCl2.
Receive tin two-chloride interaction of Sn with Cl2, NSL or chlorides of other metals.
- as the catalyst for a number of chemical reactions, including polymerizations of epoxides;
- for a covering tin of steel products in the electrochemical way, coverings of mirrors silver and drawings other thin layers of metal;
- as a reducer in organic synthesis;
- as pickle when dyeing fabrics;
- for processing of a surface of glass and plastic before metallization for adhesion increase;
- as a gumboil component when welding;
- for receiving Sn, as reagent for definition of Cl2, I, Hg2+, Fe3 +, etc.;
- for decolouration of petroleum oils;
- for check of gold ingots regarding a fake.
In the food industry it is registered as a food additive emulsifier of E512.
