Abstract
The present invention relates to the preparation of 3-methylbut-1-ene from a hydrocarbon stream I comprising isobutene by feeding a hydrocarbon stream II which comprises at least 70% by mass of isobutene in relation to the olefins present in the hydrocarbon stream and which has been obtained from hydrocarbon stream I or is identical to it to a process step for hydroformylation in which isobutene is hydroformylated in the presence of a rhodium catalyst, hydrogenating the aldehyde obtained from the hydroformylation of isobutene to the corresponding alcohol and preparing 3-methylbut-1-ene by water elimination from the alcohol.
