Main Uses: Isobutane is primarily used to produce isooctane through alkylation with isobutylene, serving as an octane rating improver for gasoline. Additionally, it can be used to produce aerosols, accelerators, polyethylene polymerization agents, polyethylene foaming agents, refrigerants, and other important basic chemical raw materials. Notably, its application as a refrigerant is increasingly replacing freon, becoming a significant cooling agent in refrigerators and air conditioners.
