Abstract
The invention relates to a process for the recovery as a feedstock of an alpha-olefin from a mixture containing mainly hydrocarbon compounds, such as is obtained by Fischer-Tropsch-synthesis after an at least crude separation of components boiling higher and/or lower than the alpha-olefin, wherein tertiary olefins of the mixture, after superstoichiometrical addition of a low alcohol, are subjected to catalytic etherification and a stream derived by etherification is fed jointly with the alpha-olefin and the ethers produced and other high boiling reaction products to a distillative separation of components boiling higher than the olefin.
