Overview
Active lime, or activated calcium oxide, is produced by calcining high-purity limestone at temperatures exceeding 1000°C. This process creates a highly porous structure with exceptional surface area and reactivity. The chemical formula is CaO (CAS No. 1305-78-8), serving as a critical reagent in industrial purification.
Application
- Petrochemical refining for removing sulfur compounds from crude oil.
- Water treatment processes to adjust pH and precipitate heavy metals.
- Pharmaceutical synthesis acting as a drying agent or reaction catalyst.
- Sugar industry decolorization and clarification of cane juice.
Precautions
- Strictly avoid contact with moisture due to exothermic hydration risks.
- Maintain storage in sealed, dry containers away from incompatible acids.
- Personal protective equipment (PPE) including goggles and gloves is mandatory during handling.
