Cyclopentane

Cyclopentane, with the chemical formula C₅H₁₀, is a highly volatile cycloparaffin. It appears as a colorless transparent liquid with a mild, petroleum-like odor. It features a very low boiling point and flash point, making it one of the most common physical blowing agents for polyurethane (PU) rigid foams. Due to its zero ozone depletion potential (ODP) and low global warming potential (GWP), it is widely used in the manufacturing of insulation layers for refrigerators and freezers. It is also used as a solvent and chemical intermediate.

  4. Fuel Additive: Can be used as a blending component in gasoline to improve octane rating.

  5. Laboratory Applications: Used as a solvent for chromatographic analysis and as a chemical reagent.

Safety Precautions


  1. Health Hazards:
    · Depresses the central nervous system. Inhalation of high concentrations can cause dizziness, headache, nausea, and even loss of consciousness.
    · Slight irritation to eyes and respiratory tract.
    · Skin contact may cause dryness and dermatitis.
    · Rapid evaporation of the liquid may cause frostbite.

  2. Handling Protection:
    · Must be handled in an explosion-proof fume hood or in a well-ventilated area.
    · Must wear chemical safety goggles, impermeable gloves, and anti-static clothing.
    · Must use explosion-proof tools and equipment.
    · Avoid contact with skin and eyes.
    · Do not eat, drink, or smoke while handling.

  3. Storage & Transportation:
    · Store in a cool, well-ventilated, explosion-proof dedicated area, temperature should not exceed 30°C.
    · Keep containers tightly closed and away from heat, sparks, open flames, and hot surfaces.
    · Use explosion-proof electrical and anti-static equipment. Containers must be properly grounded.
    · Store separately from strong oxidizers (e.g., oxygen, peroxides).
    · Store under an inert atmosphere (e.g., nitrogen) if possible.

  4. Fire Fighting:
    · EXTREMELY FLAMMABLE LIQUID AND VAPOR. Flash point -37°C. Highly flammable and explosive.
    · Vapor is heavier than air and may travel along the ground; distant ignition is possible.
    · Explosive limits: 1.5% - 8.7% (by volume in air).
    · Use foam, dry chemical, or CO2 to extinguish fire. Water is ineffective but can be used to cool exposed containers.
    · Firefighters must wear self-contained breathing apparatus (SCBA) and full protective gear.
