Изобретение относится к способу получения 1, 1, 1, 3, 3 - пентафторпропана (хладон - 245fa), являющимся озонобезопасным хладоном, который может быть использован в качестве хладагента, пропелента, вспенивающего агента и растворителя. Техническая задача, решаемая изобретением - повышение выхода целевого продукта, упрощение процесса производства 1, 1, 1, 3, 3 - пентафторпропана и расширение сырьевой базы. Данная задача решается путем взаимодействия 1, 1, 1, 3, 3 - пентахлорпропана с фтороводородом при температуре процесса 50 oC 160oС и давлении 5 oC 25 кгс/см2 в присутствии катализатора, состоящего из смеси пятихлористой сурьмы и фтороводорода в молярном соотношении SbCl5/HF от 1 oC 70 до 1 oC 1,8 и при нагрузке на катализатор 0,08 oC 1 кг 1, 1, 1, 3, 3 - пентанхлорпропана / кг SbCl5 ч.The invention relates to a method for producing 1, 1, 1, 3, 3 - pentafluoropropane (freon - 245fa), which is an ozone-friendly freon, which can be used as a refrigerant, propellant, foaming agent and solvent. The technical problem solved by the invention is to increase the yield of the target product, simplify the production process 1, 1, 3, 3 - pentafluoropropane and expand the raw material base. This task is solved by reacting 1, 1, 1, 3, 3 - pentachloropropane with hydrogen fluoride at a process temperature of 50 o C 160 o C and a pressure of 5 o C 25 kgf / cm 2 in the presence of a catalyst consisting of a mixture of antimony pentachloride and hydrogen fluoride in a molar the ratio of SbCl 5 / HF from 1 o C 70 to 1 o C 1,8 and when the load on the catalyst 0,08 o C 1 kg 1, 1, 3, 3 - pentanechloropropane / kg SbCl 5 hours
