as both natural environments and human health are concerned. In this study, investigation on degradation of HFPO oligomers to pentafluoropropionyl fluoride (PPF), a valuable industrial chemical, is reported. Different combinations of alkali metal fluoride in either diglyme or tetraglyme under both flask and batch autoclave conditions were examined. Under the optimal reaction conditions, HFPO oligomers
摘要六氟环氧丙烷(HFPO)低聚物是有毒,生物蓄积性和持久性有机污染物(POPs)。就自然环境和人类健康而言,食用有害化学物质以防止其释放到自然中具有重要意义。在这项研究中,报道了有关将HFPO低聚物降解为有价值的工业化学品五氟丙酰氟(PPF)的研究。在烧瓶和间歇高压釜条件下,研究了二甘醇二甲醚或四甘醇二甲醚中碱金属氟化物的不同组合。在最佳反应条件下,HFPO低聚物(n = 2-10)被完全降解为PPF,产率超过90%。测试了200克规模的反应,未观察到效率降低,
