Zinc Chloride
Zinc chloride is a chemical compound with formula ZnCl2 and CAS number 7646-85-7. Zinc chloride is a colorless or white, water soluble liquid which is hygroscopic as well deliquescent. Zinc chloride in an ionic solid and a mild Lewis acid, it has a pH of approx. 4. Zinc chloride have a melting point of 275 degree Celsius and boiling point 756 degree Celsius.
China and India hold the maximum share in the zinc chloride market, with increasing opportunities for zinc chloride supplier and manufacturers.
Preparation and Purification
Anhydrous form of ZnCl2 can be prepared from mixture of zinc and hydrogen chloride.
Zn(s) + 2 HCl → ZnCl2 + H2(g)
Hydrated and aqueous form can be prepared by treating zinc metal with hydrochloric acid. Zinc oxide and zinc sulfide reacts with hydrogen chloride.
ZnS(s) + 2 HCl(aq) → ZnCl2(aq) + H2S(g)
Zinc exists only in one oxidation state i.e., +2, making the purification of chloride simple.
Zinc chloride commercial samples have only water or hydrolysis products as impurities, which can be purified by recrystallization by hot dioxane. Anhydrous zinc chloride sample can be purified by sublimation and finally the simple method of purification is treating the ZnCl2 with the solution of thionyl chloride.
Applications of Zinc Chloride
- As a Metallurgical Flux
- Organic Synthesis
- Textile and Paper Processing
- Smoke Grenades
- Fingerprint Detection
- Disinfectant
- Skin Cancer Treatment
Hazards and Safety
There are some precautions to be considered by zinc chloride suppliers, manufacturers or who buy zinc chloride.
- Zinc chloride is a skin irritant; it should be immediately washed off with soap and water after contact with the skin. When in contact with eyes, wash off with plenty of water or eyes rinse and contact ophthalmologist as early as possible.
- Formation of dust or aerosols should be avoided, if formed appropriate ventilation should be provided.
- Zinc chloride can lead to hematemesis as it is caustic to gastrointestinal tract. Symptoms of intoxication are diarrhea, nausea, pain in abdomen and gastrointestinal distress. Milk can be used to reduce metal absorption. Zinc level can be stabilized through EDTA salts.
- In case of zinc fume inhalation, to avoid lung edema, cortisone preparations should be applied instantly.
- Protective equipment should be used, adequate ventilation should be ensured, leakage should be prevented.
Storage: There are some conditions for safe storage to be taken care by zinc chloride suppliers, manufacturers or buyers.
Stored should be protected from moisture, kept in well-sealed containers. Should not eat, drink or smoke when handling chemical substances. Zinc chloride should be stored in cool place and in a metal container, away from heat, ignition sources or from open flame. Keep away from foodstuffs and oxidizing agents.
