It is disclosed that alkyl amines are produced from a mixed olefin feed containing vinyl olefins with internal olefins or vinylidene olefins as impurities by a plural step process in which the mixed olefins are subjeced to a selective isomerization wherein vinylidene olefins are converted to branched internal olefins, the olefins are then hydrobrominated to produce bromoalkanes, the bromoalkanes are selectively dehydrohalogenated whereby the secondary bromoalkanes are converted to olefins leaving the primary bromoalkanes substantially unaffected, the primary bromoalkanes being subjected to amination with ammonia or a primary or secondary amine whereby they are converted to amine hydrobromides. The amine hydrobromides are then converted to amines, and the amines are recovered.
