摘要:
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.

The present invention relates to the preparation of olefins or olefin mixtures having from 8 to 12 carbon atoms from one or more olefin(s) having from 4 to 6 carbon atoms by means of a four-stage synthesis. The four-stage synthesis comprises the steps of hydroformylation to form the aldehyde, hydrogenation to form the alcohol, elimination of water to form the 1-olefin and metathesis. The C8-C12-olefins obtained can be used, for example, for peparing plasticizer alcohols, in particular isononanol.
