The result has been an upsurge in output of very light liquid fuels variously described as light condensate, drip gas, pentanes plus or natural gasoline, which compete head one with the light naphtha traditionally produced by oil refineries, an essential component in the production of both motor gasoline and petrochemicals.
These have been produced using Oxid technology that overcomes the inherently low solubility of pentanes in polyester polyols and also allows for higher functionality.
To stay frozen, the pentane would require a refrigeration system that could maintain the pentane at nearly 200[degrees]C below the freezing point of water.
We therefore developed an analytical method using SPME coupled to ion-trap detection to assess trace amounts of the hydrocarbons isoprene and pentane, the ketone acetone, the volatile anesthetic isoflurane, and the thioether dimethyl sulfide in the blood of humans and laboratory animals.
The inadequate cooling allows the remaining pentane inside the beads to continue expanding while the EPS beads are still soft and pliable.

Low-volatile EPS products--those with a pentane level of 4.
Carbon dioxide and pentane (a highly flammable chemical that contributes to smog) are also used as blowing agents.
The heat causes the pentane inside the bead to expand each bead against one another.
Duthie also found lower levels of thre other key indicators of oxidative activity in vitamin-E-supplemented, stress-susceptible pigs -- plasma malonaldehyde, peroxidized red blood cells and pentane.
Spain, Britain, Italy, Belgium, the Netherlands, Turkey, Taiwan, China, South Korea, Indonesia, Malaysia, Armenia, Azerbaijan, Saudi Arabia, Syria, India and Iraq are among the main countries importing Iran`s petrochemical products which include propane, butane, pentane, benzene, ethylene, light polyethylene, heavy polyethylene and plastic, he added.
