Abstract
In the production of ethylfluoride by reacting ethylene with hydrofluoric acid, the addition of a very minor amount of a heavier olefin such as a C.sub.3 and/or C.sub.4 olefin greatly improves conversion and selectivity of the reaction. The product ethylfluoride can be recovered by liquid-liquid extraction.
