    • Described is a process for preparing substituted butenes of the formula I and/or II, where the radical R is unsubstituted or mono- or di-C1-C10-alkoxy-substituted or mono- or dihydroxy-substituted C2-C20-alkyl or alkenyl or is C6-C10-aryl, C7-C11-aralkyl or methyl by reacting 1,3-butadiene with an alcohol of the formula ROH in which R is as defined in the presence of an acidic particulate catalyst insoluble in the reaction medium, which involves contacting the butadiene, the alcohol and the catalyst in a fluidized bed reactor which is flow-approached from below and is operated at above the loosening point.

    • Butanol and dibutyl ether are separated from a mixture containing water, dibutyl ether and n-butanol, 2-butanol and/or isobutanol by a process in whicha) the mixture is introduced into a first distillation column, essentially butanol is separated off at the bottom of this distillation column and the mixture taken off at the top of the distillation columnb) is introduced into a second distillation column and essentially dibutyl ether is separated off at the bottom of this second distillation column and the mixture formed at the top of the second distillation column is removed,c) the second distillation column being operated at a higher pressure than the first distillation column and at least one of the two mixtures taken off via the top of the distillation columns being subjected to phase separation, only the organic phase separated off being fed to the second distillation column in the case of phase separation downstream of the first distillation column, and separation into an aqueous and an organic phase also being effected in the case of phase separation downstream of the second distillation column, a part stream being recycled from the top or rectification section of the second distillation column to the first distillation column.
