Abstract: The invention relates to a method for separating a mixture containing butane-1,4-diol and at least one other compound from the following group: 4-hydroxybutyraldehyde, its cyclical hemiacetal and its cyclical whole acetals with at least one other alcohol, by distillation. The distillation is carried out in the presence of a compound which acts as an alkali. The mixture to be separated preferably contains a cyclical whole acetal of 4-hydroxybutyraldehyde with the other alcohol, this alcohol having a lower boiling temperature than butanediol and being in free form. The method is especially suitable for distilling and separating mixtures produced in the hydrogenation of maleic acid derivatives.
