• 개요

  Perfluoroisobutylene (PFIB) is a schedule 2A substance under the Chemical Weapons Convention, which means that while it has significant ability to be used as a chemical weapon, it also serves various other industrial uses.

• 용도

  Perfluoroisobutylene or perfluoroisobutene is a monomer used in synthesis of Teflon and other polymeric materials. It is also used in etching for semiconductor fabrication, and is potentially used as a chemical warfare agent. The US Food and Drug Administration’s CFR 21 Section 173.360 allows for use of octafluorocyclobutane as a propellant and also allows for PFIB at a level of <.01% as an impurity in formulation.

• Safety Profile

  A deadly poison by inhalation. Askin, eye, and mucous membrane irritant. Human acuteexposure causes marked irritation of conjunctivae, throat,and lungs. When heated to decompos

• 환경귀착

  PFIB exists as a gas in the atmosphere, and is degraded by reaction with hydroxyl radicals, with a reaction half-life of ~5.7 days. PFIB is not susceptible to significant photolysis. The Henry’s law constant of PFIB suggests volatization as an important fate process. The half lives for volatization calculated from a model lake and river were 5.6 days and 4.1 h, respectively, though a small portion will adsorb to suspended solids and sediment. PFIB can also volatize substantially from moist soils, and to a small degree from dry soils.
