Abstract

The present invention relates to a method for purification of a hydrocarbon stream containing linear alpha olefins, isomers thereof and at least one organic amine, the linear alpha olefins, isomers and the amine having boiling points under atmospheric pressure which differ by at most 5° C., comprising the step of removing a major amount of the organic amine from the hydrocarbon stream by distillation, wherein the distillation is carried out to that, together with the amine, between 5% and 95 wt % of the isomers, based on the total amount of the isomers in the hydrocarbon stream, are removed from the hydrocarbon stream in an amine/isomer-rich fraction.
