Abstract

Se describe un proceso para separar 1,1,1,2- tetrafluoropropano y fluoruro de hidrógeno de una mezcla que comprende 1,1,1,2-tetrafluoropropano, 1,1,1,2,3, pentafluoropropano y fluoruro de hidrógeno; el proceso comprende: exponer esa mezcla de 1,1,1,2-tetrafluoropropano, 1,1,1,2,3-péntafluoropropano y fluoruro de hidrógeno a una etapa de destilación para formar una composición destilada en columna que comprende una composición azeotrópica o casi azeotrópica de ese 1,1,1,2-tetrafluoropropano y fluoruro de hidrógeno y una composición de fondos de 1,1,1,2,3- pentafluoropropano. El destilado de columna puede prepararse, opcionalmente, prácticamente libre de 1, 1,1, 2,3- pentafluoropropano y la composición de fondos de la columna puede prepararse, opcionalmente, prácticamente libre de HF. Además, se describe un proceso para separar 1, 1, 1,2- tetrafluoropropano y fluoruro de hidrógeno de una mezcla de 1, 1, 1,2-tetrafluoropropan o y fluoruro de hidrógeno. Además, se describen composiciones azeotrópicas y similares a azeótropos que comprenden 1, 1, 1,2-tetrafluoropropano y fluoruro de hidrógeno.
