▎ 摘　　要

NOVELTY - Removing fluorine-containing olefin in hexafluorobutadiene comprises using graphene oxide-doped Hong Kong University of Science and Technology (HKUST-1) adsorption material as the adsorbent, introducing the hexafluorobutadiene gas containing fluorine-containing olefins at a space velocity of 40-200 h-1at adsorption temperature of 20-100℃, where the fluorine-containing olefin comprises butadiene fluorochloride and/or fluorobutene dimer. USE - The method is useful for removing fluorine-containing olefin in hexafluorobutadiene. ADVANTAGE - The method has adsorption capacity, mild adsorption conditions and low equipment requirements.
