Calcium Chloride 80% - 96%
Calcium chloride is a white crystalline solid with a wide range of applications across various industries. It dissolves easily in water, forming a clear, colorless solution. Calcium chloride is typically produced by reacting hydrochloric acid with limestone and is available in both anhydrous and hydrated forms.
Physical and Chemical Properties of Calcium Chloride
Calcium chloride (CaCl₂) is a compound composed of calcium and chloride ions, appearing as a solid and odorless at room temperature. When dissolved in water, it releases a significant amount of heat. It is available in flake, granular, or pellet form and has a high hygroscopic nature, requiring storage conditions that minimize air contact. Food-grade calcium chloride is produced with 94–96% purity, while industrial-grade has 78–80% purity.Production Methods
1. Extraction from Natural Sources: Calcium chloride is obtained from brine solutions in lakes and underground deposits. After purification, it is used for industrial applications. 2. Chemical Reaction of Limestone and Hydrochloric Acid: In this process, limestone (calcium carbonate) reacts with hydrochloric acid to produce calcium chloride and carbon dioxide. This method is primarily used for food and pharmaceutical-grade production.Main Applications
1. Oil and Gas Industry: Used as a drilling fluid to stabilize well walls and prevent formation damage. Also employed as a supplemental fluid to clean drilling mud. 2. Road De-icing: One of the main uses of calcium chloride is as a de-icing agent. It absorbs moisture and generates heat to melt ice and snow, improving road safety. It also helps reduce dust on unpaved roads. 3. Food Industry: Acts as a firming agent for fruits and vegetables, a preservative, and a flavor enhancer, helping maintain food freshness. 4. Pharmaceutical Industry: Used to regulate electrolyte balance and treat calcium deficiency. It is also found in certain injectable formulations and calcium supplements.Environmental Impact
Although calcium chloride has multiple industrial, agricultural, and medical applications, its release into the environment can contaminate soil and water, affecting natural ecosystems. Production processes may also contribute to greenhouse gas emissions, emphasizing the need for responsible use and proper waste management.Safety Guidelines
- Avoid direct contact with skin and eyes
- Wear gloves, safety goggles, and a mask when handling
- Avoid contact with metals such as zinc or sodium due to hydrogen gas formation
- Do not store near sulfuric acid or corrosive metals
- Refer to the Safety Data Sheet (SDS) for transportation and first-aid procedures
