Uses and synthesis of Stannous chloride dihydrate powder

Stannous chloride dihydrate powder, chemical formula SnCl2, also known as tin dichloride. There is no water and hydrate, the former is a transparent crystal, the melting point is 246℃, the boiling point is 652℃, and the relative density is 3.95. Stannous chloride dihydrate dissolves in water and is oxidized in air to form insoluble chloride oxides. Stannous chloride dihydrate is commonly used as reducing agent, mordant, decolorizing agent and analytical reagent in chemical industry. Used for tinning in electroplating industry. Stannous chloride dihydrate powder is obtained by the direct reaction of chlorine and molten tin. Stannous chloride hydrate can be prepared by treating sheet tin with hydrochloric acid, then evaporating and crystallizing.

Applications/Functions of Stannous chloride dihydrate powder

• Stannous chloride dihydrate powder is used for the colorimetric determination of silver, lead, arsenic, molybdenum, etc. It is also used as a reducing agent and mordant
• Stannous chloride dihydrate Stannous chloride dihydrate is mainly used in acid tin plating. Tin in the bath is a bivalent state, cathode efficiency is high, the general dosage of 40 ~ 60 kg/L. It can also be used in glass mirror industry, as a sensitizer for silver nitrate plating, so that the coating brightness is good, and the coating is not easy to fall off when adding this product in ABS plating.
• Stannous chloride dihydrate powder is used as analytical reagent and reducing agent. Reducing agent for making dye intermediates; Electroplating; It is used as brightening agent in mirror silver plating and plastic plate plating. Spices stabilizer, bleach, stable soap aroma; Anti-fouling agent of oil; Raw materials for organic synthesis; Pesticide herbicide oxalone (nongsi it) raw materials, etc.
