Zinc Chloride Description:
Zinc chloride (CAS: 7646-85-7) is an inorganic salt with the chemical formula ZnCl2. It has a wide range of industrial applications. It is readily soluble in water, methanol, ethanol, glycerol, acetone and diethyl ether, but insoluble in liquid ammonia. The compound is deliquescent and absorbs moisture from the air, consequently becoming liquid. In addition, zinc chloride is corrosive and toxic. It is used for the identification of primary, secondary and tertiary alcohols, as a dehydrating agent in organic synthesis, as a catalyst and as a condensing agent.

Zinc Chloride Applications:
Zinc chloride is primarily used for the identification of primary, secondary and tertiary alcohols, as a dehydrating agent in organic synthesis, as a catalyst and as a condensing agent.
Zinc chloride (ZnCl2) has been employed as an activating agent in the synthesis of phenol-based chemically activated carbon fibres (CAFs). It is used as a catalyst in the production of carbonyl-methylene condensation products and poly(propylene fumarate). ZnCl2 is also utilised as a catalyst in the Knoevenagel reaction.

Zinc Chloride FAQs:
Q1: What are the key properties of zinc chloride powder?
Zinc chloride powder is deliquescent; it readily absorbs moisture from the air. It is corrosive to metals and its solubility and reactivity facilitate a number of applications.
Q2: What are the most common applications of zinc chloride powder?
Zinc chloride powder is used in galvanisation processes, battery production, chemical synthesis, wood preservation, textile processing, deodorant manufacture, oil and gas drilling, electroplating and as a fire retardant.
Q3: How is zinc chloride powder normally stored?
Zinc chloride powder should be stored in a cool, dry location away from moisture and incompatible substances. It must be kept in a tightly sealed container to prevent the absorption of moisture.
