Uses

Zinc chloride is used as a wood preservative and in fireproofing timber. Other uses are as a deodorant in disinfecting fluids; in dental cements; in electroplating; in etching metals and glass; as flux for soldering; as a mordant in printing and dyeing textiles; in making dry batteries; in denaturing alcohols; in vulcanizing rubber; in manufacturing parchment; in making artificial silk; in making activated carbon and cold-water glues; and in refining petroleum. Also, zinc chloride is used as a dehydrating and condensing agent in organic syntheses. In medicine it is used as an astringent and antiseptic.

Uses

Deodorant, disinfecting and embalming material; alone or with phenol and other antiseptics for preserving railway ties; fireproofing lumber; with ammonium chloride as flux for soldering; etching metals; manufacture of parchment paper, artificial silk, dyes, activated carbon, cold-water glues, vulcanized fiber; browning steel, galvanizing iron, copper-plating iron; in magnesia cements; petroleum oil refining; cement for metals and for facing stone; mordant in printing and dyeing textiles; carbonizing woolen goods; producing crepe and crimping fabrics; mercerizing cotton; sizing and weighting fabrics; vulcanizing rubber; solvent for cellulose; preserving anatomical specimens; in microscopy for separating silk, wool, and plant fibers; as dehydrating agent in chemical syntheses. Dentin desensitizer.

Definition

ChEBI: A compound of zinc and chloride ions in the ratio 1:2. It exists in four crystalline forms, in each of which the Zn2+ ions are trigonal planar coordinated to four chloride ions.

Preparation

Zinc chloride is prepared by the reaction of zinc oxide or zinc metal with dilute hydrochloric acid, followed by crystallization:
ZnO + 2HCl → ZnCl2 + H2O
Zn + 2HCl → ZnCl2 + H2

General Description

Zinc chloride is a colorless liquid. Zinc chloride is mildly corrosive to metals. Zinc chloride causes burns to eyes, skin and mucous membranes.

Air & Water Reactions

When dissolved in water, Zinc chloride is a strong acid. [Handling Chemicals Safely 1980. p. 964]

Reactivity Profile

Acidic salts, such as ZINC CHLORIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Health Hazard

Solid or water solution is astringent and can irritate the eyes. When ingested, can cause intoxication, severe irritation of stomach, nausea, vomiting, and diarrhea.

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.

Toxicity

Inhalation of zinc chloride fumes can injure lungs and respiratory tract. Dusts or fumes also cause dermatitis, boils, conjunctivitis, and gastrointestinal tract upset (Lewis(Sr), R.J. 1996. Sax’s Dangerous Properties of Industrial Materials, 9th ed. New York: Van Nostrand Reinhold).
