Usage：
As effective catalyst carrier and internal coolant in gasphase polymerisation processes of ethylene plant, like SABIC ethylene or Sinopec ethylene plant.
Geothermal power stations have been using iso-pentane in binary cycle systems wherein warm geothermal water is brought to the surface and passed through a heat exchanger containing iso-pentane. Because of its much lower boiling point compared to water, the iso-pentane heats up the binary fluid causing the turbines to spin. The advantage is that the pentane can be re- used once it condenses and pumped back into the system.
As solvent to improve the octane value of gasoline Iso-pentane is widely used as blowing agent for PU, EPS processing.Iso-pentane is used as aerosol propellant .As chemical raw material for iso-amylene, isoprene etc.
