calcium chloride

A chemical substance consisting of chlorine and calcium with the chemical formula CaCl2. Slightly bitter. It is a typical ionic halide, white, hard fragments or particles at room temperature. Its common applications include salt water used in refrigeration equipment, road ice melting agent and desiccant. Because it is easy to absorb moisture in the air and deliquesce [5], anhydrous calcium chloride must be stored in a sealed container. Calcium chloride, its hydrate and solution have important application value in food manufacturing, building materials, medicine and biology. Calcium chloride has outstanding adsorption capacity and low desorption temperature for ammonia, so it has great application prospect in the adsorption and separation of synthetic ammonia. However, calcium chloride is not easy to form stable porous materials, the contact area with ammonia is small, and it is easy to expand and agglomerate in the process of adsorption and desorption, so it is difficult to put it into practical application. The contact area between calcium chloride and ammonia can be greatly increased by loading calcium chloride on high specific surface carrier. Previous studies have shown that the composite adsorbent prepared by loading calcium chloride on the molecular sieve has better adsorption performance and stability than the single adsorbent.
