Is pentane solvent used in refrigerators? - CAS No 109-66-0

n-pentane is a straight-chain alkane hydrocarbon with the chemical formula C5H12. It is a colorless, flammable liquid that is widely used as a solvent and in the production of gasoline.

• n-pentane chemical is the straight-chain isomer of the alkane with five carbon atoms.
• Compared to its branched-chain isomers, n-pentane has a lower boiling point due to weaker intermolecular forces.
• n-pentane is a highly flammable liquid and its vapors can form explosive mixtures with air.
• The low viscosity and high volatility of n-pentane make it useful as a solvent, propellant, and fuel component.
• pentane is a minor component of natural gas and is also produced during the refining of crude oil.

CAS 109-66-0 pentane (n-pentane) is widely used in refrigerators. It acts as a in the production of rigid polyurethane foam insulation, which lines the inner and outer walls of refrigerators and freezers. This foam insulation minimizes heat transfer between the inside and outside of the appliance, improving energy efficiency and reducing power consumption. Unlike traditional ozone-depleting blowing agents, pentane is an environmentally friendly alternative.
