Perfluorobutanoic acid (PFBA) is a perfluoroalkyl carboxylic acid with the formula C 3 F 7 CO 2 H. As the perfluorinated derivative of butyric acid, this colourless liquid is prepared by electrofluorination of the corresponding butyryl fluoride. [3] PFBA has a variety of niche applications in analytical and synthetic chemistry.

五氟苯甲酸 （PFBA）是一种 有机氟化合物，化学式为C 6 F 5 CO 2 H。 它是一种易溶于水的白色晶体粉末。 它的pK a 是1.48，显示出它是强酸。 [1] 五氟苯基锂（或五氟苯基格氏试剂）与二氧化碳反应，生成五氟苯甲酸。 这些试剂通常从 五氟苯 和五氟溴苯原位制备。 [1][2] 全氟甲苯 与 三氟乙酸 和 五氟化锑 反应会生成它。 [3] ^ Haper, R.
