A process for preparing fluorochemical compounds, e.g., perfluoroalkanes, perfluoroethers, and perfluoroalkyl tertiary amines, comprises
(a) forming a mixture comprising at least one fluorinatable, non-functional organic starting compound, e.g., propane, and at least one other compound which is present in an amount sufficient to enable the formation of a fluorochemical phase and which is selected from the group consisting of
(i) perfluorochemical compounds, e.g., perfluorohexane, which boil at a higher temperature than either the fluorinatable, non-functional organic starting compound or the fluorochemical compound resulting from the subsequent fluorination of the fluorinatable, non-functional organic starting compound; and
(ii) precursor compounds, e.g., hexane, which can be fluorinated in situ to produce such perfluorochemical compounds; and
(b) subjecting the mixture to electrochemical fluorination in the presence of anhydrous hydrogen fluoride.
一种制备氟化合物(如全氟烷烃、全氟醚和全氟烷基叔胺)的工艺包括
(a) 形成一种混合物,该混合物包括至少一种可氟化的非官能有机起始化合物(如丙 烷)和至少一种其它化合物,其含量足以形成氟化学相,该化合物选自以下组别: (b) 将至少一种可氟化的非官能有机起始化合物(如丙烷)和至少一种其它化合物(其 含量足以形成氟化学相,该化合物选自以下组别
(i) 全氟化合物,如全氟己烷,其沸腾温度高于可氟化的非功能性有机起始化合物或可氟化的非功能性有机起始化合物随后氟化产生的氟化合物;以及
(ii) 可就地氟化以生产此类全氟化合物的前体化合物,如正己烷;以及
(b) 在无水氟化氢存在下,对混合物进行电化学氟化。
