A process for preparing a Caldehyde mixture from a hydrocarbon mixture comprising at least one linear butene by terminal hydroformylation under isomerizing conditions, using a catalyst system comprising rhodium, a bisphosphite ligand, and an amine.

[object Object]

The invention relates to a process for preparing ETBE from technical mixtures which comprise at least 1-butene, isobutene, n-butane and 2-butenes, by reacting the isobutene present, distillatively removing a fraction comprising 1-butene and isobutene and again reacting the isobutene present therein to give ETBE.
