概要
イソブテン（イソブチレン）
Isobutene (isobutylene) is a colorless, flammable gas at room temperature and a fundamental C4 building block in the petrochemical industry. It is the primary monomer for butyl rubber (IIR) and polyisobutylene (PIB) production, and a key feedstock for MTBE, ETBE, and other fuel additives. High-purity isobutene (≥99%) is essential for specialty polymer applications including reactive polyisobutylene used in fuel and lubricant additives. It is shipped under pressure as a liquefied gas.
