摘要： The invention relates to a method, whereby the colour number of polyhydric alcohols, in particular, trihydroxymethylpropane, can be significantly improved by hydrogenation. The method is characterized in that an alcohol is used in the hydrogenation, which has been previously purified by distillation. The conventional catalysts for hydrogenation are used as catalysts, preferably copper, nickel, palladium or ruthenium.

摘要： 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.

摘要： A process is disclosed for the purification, by distillation, of trimethylolpropane originating from the hydrogenation of 2,2-dimethylolbutanal, said process including the following steps:(a) reaction of n-butyraldehyde with formaldehyde in the presence of catalytic amounts of a tertiary amine, and hydrogenation of the resulting mixture to give a mixture containing trimethylolpropane;(b) separation of water, methanol, trialkylamine and/or trialkylammonium formate by distillation;(c) heating of the residue obtained in (b) under reduced pressure to a temperature at which TMP is volatile and compounds boiling above TMP are cleaved, in order to separate off, by distillation, TMP and compounds more volatile than TMP;(d) distillation of the distillate obtained in (c) in order to separate off the more volatile compounds and recover pure TMP; and(e) optional distillation of the TMP obtained in (d) in order to recover TMP with a low APHA color index.A process is also disclosed in which trialkylammonium formate is distilled under mild conditions from crude mixtures of polyhydric alcohols, predominantly trimethylolpropane.
