|Section2= |Section3= }} Perfluoroisobutene (PFIB), also known as 1,1,3,3,3-pentafluoro-2-(trifluoromethyl)prop-1-ene, is a fluorocarbon alkene. It is a hydrophobic reactive gas with boiling point at 7 °C. It is a strong electrophile. PFIB is about 10 times as toxic as phosgene. Its inhalation can lead to pulmonary edema, which may be fatal. Onset of symptoms can take 1-4 hours after inhalation. Treatment is based on management of the pulmonary edema (usually with high-dose corticoids and other medication/measures) and associated disorders (e.g. heart failure, hypocalcemia etc.). Many cases resolve within 72 hours without major long-term effects. In contact with water PFIB undergoes rapid hydrolysis, producing various reactive compounds and fluorophosgene. PFIB is a product of pyrolysis of polytetrafluoroethylene (PTFE), one of the substances causing polymer fume fever. It is a Schedule 2 substance of the Chemical Weapons Convention. ==External links== * (Toxicology of Perfluoroisobutene ) * (International Chemical Safety Card 1216 ) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「perfluoroisobutene」の詳細全文を読む スポンサード リンク
