Application

Calcium chloride was used during the isolation of total β-glucan from hydrolyzed barley powders. It was also used as a cross-linker during the preparation of Aloe vera pectin gels.
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.

Caution

may contain powder and some dark grey granules
