7 Isobutane Applications and Related

Isobutane, also known as 2-methylpropane, is an organic compound with a chemical formula of C4H10. It is a colorless, flammable gas at room temperature and pressure. It is slightly soluble in water, soluble in ethanol, ether, etc., and forms an explosive mixture with air. It mainly exists in natural gas, refinery gas, and cracking gas.

Isobutane is obtained by physical separation and is mainly used to produce isooctane with isobutylene through hydrocarbonization. It is used as an improver of gasoline octane numbers and can also be used as a refrigerant.

Main Applications of Isobutane

1. Used as fuel

Isobutane is often used as a fuel, especially as a component of gasoline. It can provide energy for the engine and ensure the normal operation of the engine. Although the use of isobutane is relatively limited, it is mainly used as a fuel, but its purity is as high as 94%, which meets the basic requirements as a fuel.

2. Anti-corrosion effect

It can be used for oxidation surface anti-corrosion treatment of steel and other metals under the condition of copper oxide as a catalyst, which can effectively extend the service life of the metal.

3. Refrigerant

Isobutane is a commonly used as refrigerant, known as R600a. Its molecular structure gives it a low boiling point, so it can effectively absorb and release a large amount of heat, thus performing well in freezing and refrigeration applications. This property of isobutane makes it an ideal choice for household refrigerators, industrial refrigeration equipment, and medical refrigeration equipment.

In addition, compared with traditional chlorofluorocarbon refrigerants, isobutane is more environmentally friendly and does not cause damage to the ozone layer. Therefore, it is not only efficient but also environmentally friendly.

4. Solvent

Isobutane is mainly used as a solvent in the chemical industry. The characteristic of this solvent is that it does not chemically react to most substances, so it is considered an inert solvent. In the processing of heavy oil and lubricating oil, isobutane is often used as a solvent for deasphalting and dewaxing. In addition, it can also be used as an effective solvent when refining vegetable oils or olefin polymerization using Ziegler catalysts.

5. Industrial cooling

Isobutane has important applications in the field of refrigeration, which is often used as a refrigerant in oil refining, chemical and natural gas processing operations. Its low-temperature characteristics make it an indispensable part of these industrial processes, ensuring that equipment and processes operate at appropriate temperatures.

6. Aerosol promoter

Isobutane is mainly used as a promoter in aerosols. Aerosol is a suspension system composed of solid or liquid particles dispersed in a gas. The addition of isobutane can effectively improve the stability and spray performance of aerosols.

Isobutane has a low boiling point and good volatility; it can quickly and evenly disperse the components in the aerosol into the air. In addition, isobutane can also improve the spray distance and spray speed of aerosols, making it more suitable for various application scenarios. Therefore, it plays an indispensable role in the field of aerosols.

7. Used to make mixtures

Isobutane is mainly used to make mixtures. This mixture is commonly used in various industrial and commercial applications, including but not limited to refrigerants, propellants, and organic solvents. The chemical properties of isobutane make it an ideal choice for making these mixtures because it has a high boiling point, low toxicity, and good solubility.

These mixtures are widely used in many fields, including but not limited to aerospace, medical, and chemical production. Overall, it is versatile and efficient in making mixtures.

Hazards

Isobutane is flammable, so appropriate precautions must be taken in the production, use and maintenance of refrigeration equipment;

Isobutane can be absorbed into the body through inhalation. Short-term contact with isobutane will evaporate quickly and may cause frostbite. It may affect the cardiovascular system. It may cause functional impairment and respiratory failure. High concentrations of contact can cause death.

Storage method

  • Store in a cool, ventilated warehouse dedicated to flammable gases;
  • Keep away from fire and heat sources;
  • The warehouse temperature should not exceed 30℃;
  • It should be stored separately from oxidants and should not be mixed;
  • Use explosion-proof lighting and ventilation facilities;
  • Mechanical equipment and tools that are prone to sparks are prohibited;
  • The storage area should be equipped with leakage emergency treatment equipment.

Leakage emergency treatment

  1. Quickly evacuate personnel from the leakage-contaminated area to the upwind area, isolate them, and strictly restrict entry and exit.
  2. Cut off the source of the fire. It is recommended that emergency response personnel wear self-contained positive-pressure respirators and anti-static work clothes.
  3. Cut off the source of leakage as much as possible. Cover the sewers and other places near the leakage point with industrial coverings or adsorbents/absorbents to prevent gas from entering.
  4. Proper ventilation accelerates diffusion. Dilute and dissolve with spray water. Build dikes or dig pits to contain the large amount of wastewater generated. If possible, send the leaked gas to an open area with an exhaust fan or install appropriate nozzles to burn it. You can also move the leaking container to an open area and pay attention to ventilation.
  5. The leaking container should be properly handled, repaired, and inspected before use.

Therefore, given its characteristics, the selection and use of isobutane should be based on actual conditions and needs and must comply with the relevant laws of the country.
