Soda Lime/Carbon Dioxide Absorbent CAS 8006-28-8
Chemical Name: Soda lime/Carbon dioxide absorbent
CAS No.: 8006-28-8
Molecular Formula: CaHNaO2
Molecular Structure:
Molecular Weight:96.07
Appearance:White granule,Pink granule
Production capacity:10 tons per day
Water solubility:Soluble in water
Sample:Free samples are available
Color-changing properties:After absorbing carbon dioxide, the color gradually fades (e.g., from pink to grayish-white, or from white to purple), indicating absorption efficiency.
Product advantages: High absorption efficiency and strong ability to absorb carbon dioxide. High quality medical grade products have an absorption capacity for carbon dioxide of at least 19.0%, and even up to 30% or more.

Application
1. Medical Anesthesia: In anesthesia and intensive care, it absorbs exhaled CO₂ in the circulation loop of anesthesia machines and ventilators, allowing the exhaled gas to be re-inhaled after replenishment with oxygen and anesthetic gas, achieving "closed-loop anesthesia" and significantly conserving anesthetic gas and oxygen.
2. Diving and Confined Spaces: Used in confined environments such as diving breathing apparatus (e.g., rebreathers), submarines, spacecraft, and hyperbaric oxygen chambers to purify air and maintain breathable oxygen levels and safe CO₂ concentrations.
3. Industrial Gas Purification: In chemical and petroleum industries, it purifies hydrogen, nitrogen, inert gases, etc., removing acidic impurities such as CO₂ and H₂S.
Biogas/Natural Gas Purification: In biogas or natural gas treatment, it removes CO₂ to improve the calorific value and purity of the fuel.
Flue Gas Treatment (Small-scale or specific scenarios): Used as an alkaline absorbent to treat acidic gases.
4. Laboratory Applications
Drying and purification: Used as a highly efficient desiccant, or for experiments requiring a completely CO₂-free environment.
Synthetic reactions: Used as a basic catalyst or reactant in certain organic synthesis processes.
