Elements carbonyl difluoride

Fluorination of high molecular weight polyethers with elemental fluorine (diluted with helium) at room temperature gave fluorinated polyethers, which were depolymerized by further treatment with flowing F -He at 55-210 "C to produce carbonyl difluoride, amongst the decomposition products [1197c]. COFj is also formed in the oxidative thermal degradation of polyethers derived from hexafluoropropene oxide [1582]. Polymeric C F Oj decomposes, at an unspecified temperature, into carbonyl difluoride [760], The presence of...
