Key Properties
Soda lime granulars (CAS No. 8006-28-8) are a mixed absorbent composed primarily of sodium hydroxide and calcium hydroxide. This product is specifically designed for the efficient absorption of carbon dioxide (CO2) from gas streams, making it an essential component in various industrial and laboratory applications. Its granular form allows for easy handling and effective use in systems requiring CO2 removal. Notably, soda lime is widely utilized in medical settings, particularly in anesthesia and respiratory equipment, due to its ability to maintain a controlled environment by removing exhaled CO2.
Also known as Sodium hydroxide/calcium hydroxide mixture.

- Substance
Soda lime granulars appear as white to off-white granules, which are typically dry but can become corrosive when exposed to moisture. The product has a density of approximately 0.8 g/cm³ and is highly soluble in water, with solubility values exceeding 100 g/L. The melting point of the individual components (sodium hydroxide and calcium hydroxide) is around 318 °C and 580 °C, respectively, although the mixture does not have a defined melting point. The product is alkaline with a pH value greater than 12 when dissolved in water, indicating its corrosive nature. It is important to handle this material with care to avoid skin and eye irritation.

Soda lime granulars are primarily used as a CO2-scrubbing absorbent in various applications, including gas analysis, anesthesia circuits, and closed-system respiration research. In medical settings, it is crucial for maintaining the quality of inhaled gases by removing carbon dioxide from exhaled air, thus preventing hypercapnia in patients. Additionally, soda lime is employed in laboratory settings for gas purification and in industrial processes where CO2 removal is necessary, such as in the production of certain chemicals and in environmental monitoring systems.
