Stannous chloride Chemical Properties,Uses,Production
Chemical Properties
Stannous chloride is a white crystalline solid.
Physical properties
White orthogonal crystal; density 3.90 g/cm3; melts at 247°C; vaporizes at 623°C; vapor pressure 1 torr at 316°C, 5 torr at 366°C and 20 torr at 420°C; soluble in water, ethanol, acetone and ether; insoluble in xylene and mineral spirits.
TIN(II) CHLORIDE 937The dihydrate, SnCl2•2H2O, is a white monoclinic crystalline substance; density 2.71 g/cm3; absorbs oxygen from air forming an oxychloride; melts at 37°C on rapid heating; decomposes on strong heating; very soluble in water; forms an insoluble basic salt with excess water; very soluble in hydrochloric acid; soluble in caustic soda solution, ethanol and ethyl acetate.
Uses
Stannous Chloride is an antioxidant and preservative that exists as white or colorless crystals, being very soluble in water. it reacts read- ily with oxygen, preventing its combination with chemicals and foods which would otherwise result in discoloration and undesirable odors. it is used for color retention in asparagus at less than 20 ppm. it is also used in carbonated drinks.
Definition
ChEBI: An inorganic chloride that has formula Cl2Sn.
Preparation
Tin(II) chloride is prepared by dissolving tin in hydrochloric acid followed by evaporation of the solution and crystallization.
General Description
Crystalline mass or flaky solid with a fatty appearance. Density 3.95 g / cm3. Melting point 247°C. Burns, but may be difficult to ignite. Toxic by ingestion. Irritates skin and eyes. Used in the manufacture of dyes, pharmaceuticals and as a tanning agent.
Air & Water Reactions
Water soluble.
Reactivity Profile
STANNOUS CHLORIDE is a powerful reducing agent. Can react violently with oxidizing agents. Undergoes flaming reaction with bromine trifluoride [Mellor 2 Supp. 1:164 1956]. Catalyzes the exothermic rearrangement and polymerization of ethylene oxide [J. Soc. Chem. Ind. 68:179 1949]. Mixtures with calcium carbide can be ignited with a match, and the reaction proceeds with incandescence [Mellor 7:430 1946-47]. Reacts with hydrazine hydrate to give stannous dihydrazine chloride which decomposes explosively when heated [Mellor 7:430 1946-47]. Undergoes a strongly exothermic reaction with aqueous solutions of hydrogen peroxide having concentration exceeding 3%) [Chem. & Ind., 1949, 657].
Hazard
Irritant to skin, use in foods restricted to 0.0015%, as tin.
Health Hazard
TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
Fire Hazard
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.
Safety Profile
Poison by ingestion, intraperitoneal, intravenous, and subcutaneous routes. Experimental reproductive effects. Human mutation data reported. Potentially explosive reaction with metal nitrates. Violent reactions with hydrogen peroxide, ethylene oxide, hydrazine hydrate, nitrates, K, Na. Ignition on contact with bromine trifluoride. A vigorous reaction with calcium acetylide is initiated by flame. When heated to decomposition it emits toxic fumes of Cl-. See also TIN COMPOUNDS.
Potential Exposure
Stannous chloride is used as a dye, pigment, and printing ink; in making chemicals; chemical preservatives; food additives; polymers, textiles, glass, silvering mirrors.
Shipping
UN3260 Corrosive solid, acidic, inorganic, n.o.s., Hazard class: 8; Labels: 8-Corrosive material, Technical Name Required.
Purification Methods
Analytical reagent grade stannous chloride dihydrate is dehydrated by adding it slowly to vigorously stirred, redistilled acetic anhydride (120g salt per 100g of anhydride) in a fume cupboard. After ca an hour, the anhydrous SnCl2 is filtered on to a sintered-glass or Büchner funnel, washed free from acetic acid with dry Et2O (2 x 30mL), and dried under vacuum. It is stored in a sealed container. [Stephen J Chem Soc 2786 1930, Williams Org Synth Coll Vol III 627 1955.]
Incompatibilities
A strong reducing agent. Reacts violently with oxidants. Reacts violently with bromine trifluoride; potassium, hydrazine hydrate, sodium, sodium peroxide; ethylene oxide; and nitrates. Keep away from moisture, sources of oxygen, and combustible materials.
