This abstract first appeared for US patent application 18739599 titled 'PROCESS FOR THE HYDROFORMYLATION OF DIISOBUTENE WITH PRECEDING DISTILLATION

Original Abstract Submitted

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 hydroformylation is carried out with synthesis gas in the presence of a homogeneous catalyst system that comprises at least Co or Rh and optionally a phosphorus-containing ligand.
