Properties of Carbon Dioxide (CO2)

MSDH of CO2

Properties of CO2

Co2 Molecule - Properties of Cryogenic CO2

Physical properties of CO2 :-
Carbon dioxide is a colorless & odorless gas. It is soluble in water, ethanol , acetone and has the following properties :

  • Melting Point : -55.6 degC
  • Boiling Point : -78.5 degC
  • Density : 1.977
 

Chemical properties of CO2 :-

  • Carbon dioxide is a linear covalent molecule.
  • Carbon dioxide is an acidic oxide and reacts with water to give carbonic acid.
  • CO2 + H2O ==> H2CO3
  • Carbon dioxide reacts with alkalis to give carbonates and bicarbonates.
  • CO2 + NaOH ==> NaHCO3 (Sodium BiCarbonate )
  • NaHCO3 + NaOH ==> Na2CO3 (Sodium Carbonate) + H2O
 

Uses of CO2

  1. It is used to neutralize alkaline water.
  2. Carbon dioxide is used as an additive to oxygen for medical use as a respiration stimulant
  3. Liquid Frozen Carbon Dioxide (Co2) is a good solvent for many organic compounds.
  4. Liquid Frozen Carbon Dioxide (Co2) is used as a propellant in aerosol cans, it replaces more environmentally troublesome alternatives
  5. It is used for refrigeration and cooling.
  6. It is used as an inert gas in chemical processes, in the storage of carbon powder and in fire extinguishers.
  7. It is used in solid as well as in liquid form
  8. It is used in metal industry in the formation of casting molds to enhance their hardness
  9. Carbon dioxide gas is used to carbonate soft drinks, beers and wine and to prevent fungal and bacterial growth.
  10. Large quantities are used as a raw material in the chemical process industry, especially for methanol and urea production.
  11. It is used in oil wells for oil extraction and maintain pressure within a formation
  12. Liquid or solid carbon dioxide is used for quick freezing, surface freezing, chilling and refrigeration in the transport of foods etc.

Material Safety Data Sheets (MSDS) of CO2

 

Hazards Identification:

  • Emergency Overview: Amber glass bottle packed inside a cardboard box. Clear, orange colored solution with camphor like odor. May cause eye irritation. For eyes-only.
  • Eye: May cause temporary stinging, burning and conjunctival redness.
  • Skin: May cause irritation, dermatitis and hypersensitivity in some individuals
  • Ingestion: May cause irritation and hypersensitivity in some individuals. Will produce a yellow or green discoloration to the mouth.
  • Inhalation: Aspiration of the medication may produce irritation and hypersensitivity in some individuals.
  • Chronic Effects: Prolonged use may delay wound healing and is not recommended.
  • Target Organs: Eyes, skin and central nervous system.
  • Medical Conditions Aggravated by Long Term Exposure: This preparation should be used cautiously and sparingly in patients with cardiac disease, hypothyroidism or allergies.

First Aid Measures:

  • Skin: Remove all contaminated clothing and wash skin with copious amounts of water for at least 20 minutes. Contact physician if skin becomes irritated.
  • Eyes: Rinse immediately with copious amounts of water for at least 20 minutes. Contact a physician.
  • Inhalation: Remove person to fresh air, and if breathing stops, use artificial respiration. Contact physician.
  • Ingestion: Wash out mouth and drink plenty of water and bland fluids. The use of an emetic drug and/or gastric lavage is advisable. Do not give anything to an unconscious person. Contact physician.

Fire Fighting Measures:

  • Hazardous Products: Emits toxic fumes, nitrogen oxides (NOx), carbon monoxide (CO) and carbon dioxide (CO2).
  • Fire Fighting Instructions: Wear self-contained breathing apparatus and protective clothing. Use water spray to keep fire-exposed containers cool. Do not spray water into the burning material.
  • Extinguishing Media: Dry chemical, carbon dioxide, halon, water spray or fog, and foam on surrounding materials.

Accidental Release Measures

  • Large/Small Spills: Use personal protective equipment. Contain the spill to prevent drainage into sewers, drains or streams. Use absorbent material to solidify the spill. Shovel up solidified waste.

Handling and Storage

  • Handling: Avoid contact with product and use caution to prevent puncturing containers. No special protective equipment or procedures are required in the clinical or home environment.
  • Storage: Store product upright in original containers with the cap tightly closed at a controlled room temperature 150-300 C (590- 860 F).
