More Information
Summary:The invention concerns a method for purifying and drying a hydrofluoroolefin stream comprising a hydrofluoroolefin, water and impurities composed of halogenated carbon compounds, characterised in that said stream is brought into contact with an adsorbent and in that the purification and the drying processes are carried out simultaneously in one and the same step, said hydrofluoroolefin being a compound of formula (I): CX1X2═CX3CX4X5X6 in which each Xi (i ranging from 1 to 6) represents, independently of one another, a hydrogen atom or a chlorine or fluorine atom, it being understood that at least one of the Xi's represents a fluorine atom.
