General description

Calcium chloride (CaCl2) is an inorganic compound that is used as a Lewis base catalyst in organic synthesis. Additionally, it is also used as a drying agent in laboratories for drying liquids such as acetone, ethers, numerous esters, aliphatic, olefinic, aromatic, halogenated hydrocarbons, and neutral gases.

Application

Calcium chloride can be used as a catalyst in glucose thin-film pyrolysis experiments. It is also used as the electrolyte in the electro-deoxidation of solid zirconium oxide.

Features and Benefits

  • Increased efficiency – Eliminates time and effort of loosening hardened powders      
  • Safety – Eliminates tools of force used to break up clumps
  • Ecology – Reduces waste as it does not stick to the packaging
  • Economy – Faster preparation and solvation increase productivity and reduce costs      
  • Assured Quality – Excellent, expert-tested quality with no anti-caking agents  
  • Flexible volumes – Available from research amounts to scale-up quantities
