Molecular Weight 319.22 g/mol

Zinc iodide (ZnI₂) is an inorganic compound made of zinc and iodine. It is a white, crystalline powder that is hygroscopic, meaning it readily absorbs moisture from the air and turns brown when exposed to light or air. Zinc iodide is soluble in water, alcohol, and alkaline solutions and is used as a catalyst in organic synthesis and as a component in some medical and dental applications. It can be prepared by reacting zinc and iodine in refluxing ether or in an aqueous solution.

Industrial Uses

1. Performance Chemicals

  • Friedel-Crafts alkylation and acylation: These reactions involve attaching alkyl or acyl groups to aromatic rings, and ZnI₂ can act as a catalyst to initiate these reactions. 
  • Acylation, alkylation, and condensation reactions: Zinc iodide can catalyze a range of other reactions involving these types of functional groups.
  • X-ray Screens: Zinc iodide scintillators are used in X-ray screens to convert X-ray photons into visible light, enabling image capture.
  • Infrared Optics: ZnI₂ is transparent in the infrared region, making it useful for infrared windows and lenses.

2. Fabric Solutions

  • Mordant in Dyeing: Zinc iodide acts as a mordant, a substance that forms a bridge between the dye and the fabric fibers, making the color more permanent. This is especially important for textiles where colorfastness is crucial.
