Isopentane is widely used, first of all is an important refrigerant for the olefin plant LLDPE device condensation inducer and LNG mixed refrigerant components; used to reconcile the oil octane number; widely used in organic synthesis reaction And the separation and purification of organic matter; followed by isopentane dehydrogenation can be made of isopentene and isoprene, chlorinated and hydrolyzed from isoamyl alcohol, it is also an important organic synthesis of raw materials. Isopentane can also be used with n-pentane in EPS (expandable polystyrene) foaming agent, but also with cyclopentane, used as a rigid polyurethane foam blowing agent
