conducted on the vapor-phase dehydrofluorination of 2H,3H-decafluoropentane. It was found that 2H,3H-decafluoropentane could be dehydrofluorinated to give Z-1,1,1,2,4,4,5,5,5-nonafluoro-2-pentene and Z-1,1,1,3,4,4,5,5,5-nonafluoro-2-pentene over chromium fluoride or aluminum fluoride catalysts. With stoichiometric calculation, Z-isomer was the main product in the dehydrofluorination owing to its lower relative
对 2H,3H-十氟戊烷的气相脱氟化氢进行了研究。发现 2H,3H-十氟戊烷可以脱氟化氢得到 Z-1,1,1,2,4,4,5,5,5-nonafluoro-2-pentene 和 Z-1,1,1,3, 4,4,5,5,5-nonafluoro-2-pentene 在氟化铬或氟化铝催化剂上。通过化学计量计算,Z-异构体由于其相对能量较低,是脱氟化氢反应的主要产物,这与实验结果一致。因此,提出了2H、3H-十氟戊烷选择性脱氟化氢的反应机理。
