Abstract: A process for the separation of mixtures containing halocarbons and hydrogen fluoride. Either water alone or a blend comprising water and hydrogen fluoride is added to a mixture comprising a halocarbon and hydrogen fluoride to thereby form a first phase rich in the halocarbon and a second phase rich in hydrogen fluoride and water. The most preferred halocarbon is 1,1,1,3,3-pentafluoropropane. Preferably, the first and second phases are then separated. Optionally, the second phase rich in hydroger fluoride and water is also separated.

Abstract translation: 用于分离含有卤代烃和氟化氢的混合物的方法。 将单独的水或包含水和氟化氢的混合物加入到包含卤化碳和氟化氢的混合物中，从而形成富含卤化碳的第一相和富含氟化氢和水的第二相。 最优选的卤代烃是1,1,1,3,3-五氟丙烷。 优选地，分离第一和第二相。 任选地，富含氟化氢和水的第二相也被分离。
