Abstract: A process is developed for the hydroformylation of diisobutene, in which the diisobutene stream used is subjected to a distillation prior to the hydroformylation in order to enrich 2,4,4-trimethylpent-1-ene in the stream to be hydroformylated.

The process includes providing an input stream containing 2,4,4-trimethylpent-2-ene and 2,4,4-trimethylpent-1-ene and performing the isomerization with the input stream using a heterogeneous catalyst based on a zeolite or an ion-exchange resin. A proportion of 2,4,4-trimethylpent-2-ene in the total stream is at least 25 mol % based on the total input stream.
