  • Process for the metathesis of partly fluorinated hydrocarbons
    Patent number: 5146017
    Abstract: A process is described for the reaction of at least one partly fluorinated alkene with catalysts containing tungsten complex compounds, at 10.degree. to 200.degree. C., if appropriate in the presence of at least one inert solvent. A mixture of a partly fluorinated alkene with another partly fluorinated alkene or with a non-fluorinated alkene can also be employed for the reaction. Longer-chain partly fluorinated compounds are thereby obtained which contain at least one internal C.dbd.C double bond. Ethylene or a short-chain alkene is furthermore produced and is separated off from the reaction mixture. The longer-chain partly fluorinated compounds are valuable intermediates and can be hydrogenated to give, for example, highly heat-resistant special lubricants.
