STANNOUS CHLORIDE Chemical Properties,Uses,Production

Chemical Properties

Also known as tin chloride, tin crystals, tin dichloride and tin salts, SnCl2 is white crystals, soluble in water, alcohol, and alkalies, oxidized in air to the oxychloride, that melt at 247°C. Used as a chemical intermediate, reducing agent, and ink-stain remover, and for silvering mirrors.

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

Synthesis of tin(IV) octaethylcorroles was accomplished with this reagent. These new compounds exhibit reversible oxidation only at the conjugated ring system, not at the metal center.1

Uses

Tin (II) chloride is a strong reducing agent and is used in many industrial processes, such as manufacturing dyes, phosphors, and polymers. The compound is a major ingredient in acid tin plating baths. Other uses are a mordant in dyeing; an additive to lubricating oil to prevent sludging; a stablizier for perfume in soaps; in removing ink stains; a sensitizing agent for glass, paper, and plastics; and a soldering flux. Tin(II) chloride is used for preparing a number of tin(II) salts. It is a catalyst in many organic reactions. It is a common laboratory reagent.

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.

First aid

Move victim to fresh air. Call 911 or emergency medical service. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. Remove and isolate contaminated clothing and shoes. In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin. Keep victim warm and quiet. Effects of exposure (inhalation, ingestion, or skin contact) to substance may be delayed. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy.

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.
