    Abstract: A process for preparing oligomers by continuous oligomerization of butenes is described, wherein a) a feed stream (1) comprising I-butene and 2-butene in a total concentration of from 10 to 70% by weight and from 10 to 60% by weight of isobutane is reacted until more than 60% by weight of the I-butene comprised in the feed stream (1 ) but less than 50% by weight of the 2-butene comprised in feed stream (1) have been converted into oligomers. b) The oligomers obtained in a) are separated off and optionally passed to a further work-up and the remaining residual stream is fed to work-up by distillation. c) Isobutane is separated off by distillation from the residual stream, and d) the isobutane-depleted stream obtained after the work-up by distillation c) is reacted to form oligomers.

    Abstract: The present invention relates to a method for thermal integration in the production of saturated C3-C20 alcohols, in which a hydrogenation feed containing at least one C3-C20 aldehyde is hydrogenated in a hydrogenation zone in the presence of a hydrogen-containing gas, an output is discharged from the hydrogenation zone and subjected to distillation in at least one distillation column, wherein a fraction enriched with saturated C3-C20 alcohols is obtained.

    Abstract: Treatment of wastewater from an aldolization process, containing dissolved and/or dispersed organic impurities, comprises acidifying the wastewater to pH 0-6 and extracting it with an organic liquid produced by stripping the acidified or acidified and extracted wastewater, condensing the stripped compounds and phase-separating the condensate. An independent claim is also included for treatment of wastewater from an aldolization process, containing dissolved and/or dispersed organic impurities, by acidifying the wastewater to pH 0-6, extracting it with an organic liquid and removing volatile organic impurities and a stripping apparatus, where the organic liquid is a low boiler fraction from the distillation of a crude alcohol produced by hydrogenating an aldehyde, the alcohol/aldehyde being n-butanol/n-butyraldehyde, isobutanol/isobutyraldehyde, n-pentanol/n-valeraldehyde, n- and isopentanol/n- and isovaleraldehyde, 2-ethylhexanol/2-ethylhexenal and/or 2-propylheptanol/2-propylheptenal.
