  • Publication number: 20140378717
    Abstract: The invention relates to a method for preparing olefin fluorine compounds. Specifically, the invention relates to a method for producing a (hydro)fluoroolefin compound, including: (i) in an agitated reactor provided with at least one reactant inlet and at least one outlet, contacting, with potassium hydroxide in an aqueous reaction medium, at least one compound containing three to six carbon atoms, at least two fluorine atoms, and at least one hydrogen atom, with the proviso that at least one hydrogen atom and one fluorine atom are located on adjacent carbon atoms, so as produce the (hydro)fluoroolefin compound, separated in a gaseous state from the reaction medium and from potassium fluoride; (ii) in an aqueous medium, contacting the potassium fluoride formed in step (i) with calcium hydroxide in a second reactor so as to produce potassium.
