General description

Calcium chloride (CaCl2) is inexpensive, easily available calcium salt with a wide range of applications. It is a key component in deicers as it melts snow and ice. Reports suggest that CaCl2 helps in preserving the firmness of fresh-cut fruits and vegetables during the storage.

Application

Calcium chloride was used during the assay of transglutaminase (TG) activity. It was also used for of modification of calcium alginate hydrogels.
It may be used in the following processes:
  • Modification of natural zeolite to increase its ability of fluoride removal.
  • Synthesis of calcium sulfate whiskers utilized in making polymer reinforcing composite materials.
  • Synthesis of calcium chloride-anodized aluminum composites, a solid sorbent.
  • As an extractant in the soil analysis process.
  • As a catalyst in the synthesis of aldols by reacting dimethylsilyl (DMS) enolates with aldehydes.
