<p>1,1,1,3,3-Pentafluoropropane may be prepared by reacting 1,1,1,3,3-pentachloropropane and hydrogen fluoride in the presence of hydrofluorination catalyst. 1,1,1,3,3-Pentachloropropane may advantageously be obtained by reacting vinyl chloride with tetrachloromethane in the presence of a telomerisation catalyst and a nitrile.</p> |
