  Thermoanalytical and preparative investigations of the decomposition of potassium perfluoroorganyl(fluoro)borate salts, K[RFBF3] (RF=perfluoroalkyl, -alkenyl, -alkynyl, and -aryl groups) and K[(RF)2BF2] (RF=C6F5 and C6F13)

  摘要：

  Potassium perfluoroalkenyl(fluoro)borates, K[RFBF3], (R-F = CF2=C(CF3), cis-CF3CF=CF, and cis-C6F13CF=CF) decomposed at 208-225 degrees C (T-max, dTG). The K[RFBF3] salts (R-F = C3F7, C6F13, trans-CF3CF=CF, and trans-C4F9CF=CF) decomposed at 273-312 degrees C (T-max, dTG). Both groups of salts formed volatile polyfluoroorganics and K[BF4] as solid residue. The preparative thermolysis of selected prototypical salts K[RFBF3] showed that the polyfluoroorganics consisted of a mixture of internal perfluorohexenes, C6F12, and 1-H-tridecafluorohexane, C6F13H, in case of K[C6F13BF3], and of perfluorooctynes, C8F14, and cis-C6F13CF=CFH in case of K[cis-C6F13CF=CFBF3]. The salts K[(C6F5)(2)BF2] and K[RFBF3] (R-F = CF3C C, CF3CF=CFC C, C6F5C C, C6F5, 2,3,5,6-C5NF4) decomposed in the temperature range 249-337 degrees C (T-max, dTG) and mainly resulted in non-volatile polyfluoroorganics besides K[BF4]. The reaction path of the thermolysis of perfluoroalkyl-, perfluoroalkenyl-, and perfluorophenyl-(fluoro)borates is discussed and compared with that of perfluorocarboxylates.
