The present invention provides a method for isolating and purifying 1,1,1,2,2-pentafluoroethyl iodide or hydrogen fluoride from a mixture of 1,1,1,2,2-pentafluoroethyl iodide and hydrogen fluoride, characterized by distilling an azeotropic mixture of 1,1,1,2,2-pentafluoroethyl iodide and hydrogen fluoride from a mixture containing 1,1,1,2,2-pentafluoroethyl iodide and hydrogen fluoride either after liquid&mdash;liquid separation when the mixture is heterogeneous or directly when the mixture is homogeneous to obtain 1,1,1,2,2-pentafluoroethyl iodide or hydrogen fluoride from the bottom of the distillation column.
