Stannous chloride dihydrate Chemical Properties,Uses,Production

Chemical properties

It appears as colorless or white monoclinic crystal, being soluble in alcohol, ether, acetone and glacial acetic acid.

Solubility in water

Solubility in 100 ml of water:84 g/0 ° C

Identification test

Use a dilute hydrochloric acid test solution (TS-117) to prepare a 5% sample solution. Add drop wise of the mercuric chloride test solution (TS-138) to produce a white or off-white precipitate.
The result of the chloride test (IT-12) of the 5% sample solution was positive.


(1) It can be used as a reducing agent, mordant, bleaching agent and for tin plating in the electroplating industry.
(2) Stannous chloride dihydrate can be used for the colorimetric determination of silver, lead, arsenic and molybdenum, being also be used as a reducing agent and mordant
(3) This product is mainly used in acidic tin plating as major salt. Tin is in bivalent in the bath with high efficiency cathode. The general usage amount is 40~60 kg/L. It can also be used for glass mirror industry, as silver nitrate sensitizer to enable excellent coating brightness. Addition of the plating layer of this product during the ABS electroplating is not easy to fall off.
(4) Stannous chloride dihydrate can be used as the reducing agents in the manufacture of dyestuff intermediates. It can act as the components of super high pressure lubricating oil. It can be used as a bleaching agent for the sensitization of the mercury-plating during the manufacturing of mirror, enables excellent brightness of the formed silver film so that the combination of mercury and products is quite firm. Electroplating industry applied it for the tin-plating, copper-tin plating of the mechanical parts. During the ABS plastic plating, it is used for sensitization so that the coating is not easy to fall off. It can also be used in the synthesis of pharmaceuticals, as the catalyst in organic synthesis and the activator of the butyl rubber vulcanization. It can also be used as the mordant and the anti-dyeing agent in printing discharge process. It can be used as the stabilizers for perfumery industry, as food reductant and antioxidants used for canned asparagus, pineapple juice.
(5) It can be used as analysis reagents and reducing agent. It can also be used as the reductant for the production of dye intermediates; it can also be used for electroplating; as brightening agent during galvanized silver plating and plastic plate plating; as perfume stabilizer, bleach, stabilizing soap aroma; oil anti-fouling agent; raw material for organic synthesis; the raw material of herbicide Oxadiazon.
(6) It is a kind of strong reducing agent. It can be used for the determination of hydride via AAS; colorimetric determination of silver, lead, arsenic and molybdenum; determination of serum inorganic phosphorus and alkaline phosphatase activity, molybdenum blue method for the determination of soil and plant phosphorus content; the catalyst of the organic reaction.
(7) As a strong reducing agent, it is used for carbonyl allylation reaction; as the Lewis acid catalyst in a C-C bond reaction; the catalyst for the co-acting with AgClO4 for the synthesis of α-glycosides, the synthesis of such olefins, diolefins, cis-vinyl ethylene oxide and allyl selenide and de-oxidation of internal peroxides; used for the protection of carboxylic acids in the presence of 1,3-dithianes and selective methoxybenzyl ether scavenging reagents; the additives in hydroformylation and carbonylation reactions.

Content analysis

Accurately weigh about 2 g of sample and place it into a 250 ml volumetric flask. Add 15 l hydrochloric acid to solve it and use water to se the final volume, mix uniformly. Take 50 mL of this solution to place in a 500ml flask, add 5g potassium sodium tartrate and mix uniformly. Apply the cold saturated solution of sodium bicarbonate to adjust to alkaline (with litmus paper) and immediately titrate with 0.1mol/L iodine solution and take starch test solution (TS-235) as the indicator. Every mL of 0.1 mol/L iodine solution corresponds to 9.48 mg of stannous chloride (SnCl2) or 11.28 mg of stannous chloride dihydrate (SnC12.2H2O).


ADI 0~2mg/kg (FAO/WHO, 2001); Irritating to skin; Toxic, allowable content of air: 2mg/m. (In terms of Sn);
GRAS (FDA, § 184.1845, 2000);
LD50: 700 mg/kg (rat, oral);
During the production process of making Tin flower, we should avoid inhalation of tin dust, so as to avoid suffering from chronic bronchitis. The contact of stannous chloride solution with the skin can cause eczema. The maximum allowable concentration of the inorganic compound of tin in the United States is 2 mg/m3 (calculated based on metal tin). The production personnel should wear overalls, wear protective masks and gloves and other labor insurance products, paying attention to the protection of respiratory organs, protect the skin. The production equipment should be closed and the workshop should be well ventilated.

Usage limit

FDA/WHO(1984, mg/kg): canned asparagus 25 (only used for glass bottles of painted cans of canned asparagus, calculated based on Sn); pineapple juice 8 that merely preserved by physical methods (for reconstituted fruit juices, fruit juice prepared from frozen concentrated juice).
FDA, §172.180 (2000): canned asparagus color protection, 20mg/kg (Sn).
FDA, § 184.1845 (2000): various foods, 0.0015% (in Sn).

Production method

Tin can be dissolved in hydrochloric acid to derive.
Hydrochloric acid method: first melt the metal tin, and then pour into cold water to enable to the formation of the tin flower. Hydrochloric acid and tin flower are further added at a certain proportion into the reactors for reaction until the solution concentration of 40 ° Bé or so. It is further put into the enamel evaporator for concentration. First of all, add tin flower to the evaporator; through steam heating, have hydrochloric acid to further react with tin. When the solution concentration is increased to 73~77 ° Bé, filter while hot and then cool for crystallization and perform centrifugal separation to obtain the finished product of Tin. its
Sn + 2HCl → SnC12 + H2 ↑
