Abstract

A találmány tárgya eljárás legalább egy hidrofluoralkánt és hidrogén-fluoridot tartalmazó keverék elválasztására, amelynek során ahidrofluoralkán/hidrogén-fluorid keveréket katalizátor nélkülreagáltatják legalább egy olyan szerves vegyülettel, amely hidrogén-fluoriddal reagálni képes. A találmány tárgya továbbá eljáráshidrofluoralkán előállítására, amelynek során az első reakciólépésbena hidrofluoralkán legalább egy klórozott vagy klórozott-fluorozottprekurzorát reagáltatják hidrogén-fluoriddal, és egy ezt követőreakciólépésben az első lépésben keletkezett termékek legalább egyrészét reagáltatják hidrogén-fluoriddal, a reakciólépések egyike afenti elválasztási eljárást tartalmazza. A találmány tárgykörébetartoznak még azeotróp vagy pszeudoazeotróp készítmények, amelyeklényegében 1,5-27,5 mol% 1,1,1,3,3-pentafluorbutánt és 72,5-98,5 mol%hidrogén-fluoridot tartalmaznak. Ó
