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.

Abstract: The present invention provides a process for preparing 1,6-hexanediol by hydrogenating dialkyl adipates, alkyl 6-hydroxycaproates, 1,4-cyclohexanedione and 4-hydroxycyclohexan-1-one as ester mixtures comprising impurities, by a) freeing resulting the esterification mixture of excess alcohol and low boilers in a first distillation stage (alcohol removal), b) carrying out a separation of the bottom product in a second distillation stage into an ester fraction substantially free of 1,4-cyclohexanediols and a fraction comprising at least the majority of the 1,4-cyclohexanediols, c) catalytically hydrogenating the ester fraction substantially free of 1,4-cyclohexanediols (ester hydrogenation) and d) in a purifying distillation stage, obtaining 1,6-hexanediol from the hydrogenation effluent in a manner known per se, which comprises selectively hydrogenating the ester mixture before stage a) and/or before stage b) (purifying hydrogenation).

Abstract: The present invention provides a process for preparing polyoxyalkylene glycols of a certain molecular weight in one stage by copolymerizing tetrahydrofuran and alpha,omega-diols as the comonomer in the presence of a heteropolyacid and of a hydrocarbon, by distilling off a mixture of water and this hydrocarbon from the copolymerization, which comprises terminating the polymerization when this molecular weight is attained by adding water, comonomer, butanediol or butanediol-water mixtures.
