Abstract: The present invention relates to a lubricant comprising a polyacrylate which contains a C13/15 acrylate in polymerized form, where the C13/15 acrylate comprises at least 70 wt % of linear and branched C13 and C15 alkyl (meth)acrylates. It further relates to the polyacrylate, to the C13/15 acrylate, to a method for preparing the polyacrylate by free-radical polymerization of the C13/15 acrylate, and to a method for preparing a lubricant by contacting the polyacrylate to a base oil.

Abstract: The invention concerns a method for providing a high-purity n-butanol product stream from a crude n-butanol feed stream by fractional distillation in a dividing wall column (102) including an upper section (104), a middle section and a lower section (110), the middle section including an inflow section (106) and an offtake section (108) laterally separated from each other by a dividing wall (112) fixed in the column, the crude n-butanol feed stream being fed to the inflow section (106) and the high-purity n-butanol product stream being withdrawn from the offtake section (108), the liquid stream flowing out of the upper section (104) being collected and divided into a first liquid stream (114) and a second liquid stream (116), the first liquid stream (114) being fed to the upper region of the offtake section (108) and the second liquid stream (116) being fed to the upper region of the inflow section (106), wherein the split ratio between the mass flow rate of the first liquid stream (114) and the mass flow rate of the second liquid stream (116) is from 2:1 to 5:1.

Abstract: A process for preparing C4 to C10 monohydroxy compounds from a bottom fraction arising in the distillation of a crude mixture of C4 to C10 oxo-process aldehydes from cobalt-catalyzed or rhodium-catalyzed hydroformylation, or in the distillation of a crude mixture of C4 to C10 oxo-process alcohols, which comprises contacting the bottom fraction in the presence of hydrogen with a catalyst comprising copper oxide and aluminum oxide, at a temperature of 150° C. to 300° C. and a pressure of 20 bar to 300 bar and subjecting the resulting crude hydrogenation product to distillation, and the amount of C4 to C10 monohydroxy compounds present in the crude hydrogenation product after the hydrogenation being greater than the amount of C4 to C10 monohydroxy compounds given stoichiometrically from the hydrogenation of the ester and aldehyde compounds present in the bottom fraction, including the C4 to C10 monohydroxy compounds still present in the bottom fraction before the hydrogenation.
