摘要： Wastewater from the aldolization reaction is purified by adjusting its pH to 0 to 6, followed by extraction with monohydric alcohols having at least 8 carbon atoms, hydrocarbons having at least 6 carbon atoms, and mixtures thereof. In some cases, adjustment of the pH causes the formation of an organic phase, which is separated from the remaining wastewater before extraction.

摘要： A process for the preparation of alcohols by reaction of organic carbonyl compounds with hydrogen in two stages at elevated temperature and, optionally, elevated pressure. In the first stage, hydrogen and the carbonyl compounds are fed as a gas to a copper-containing catalyst and reacted to 80 to 99.5 percent of the theoretical conversion. In the second stage, the reaction product of the first stage is fed to a nickel/alumina/zirconium dioxide catalyst as a liquid, along with hydrogen. The carbonyl compounds used include aldehydes and their derivatives and, in particular, aliphatic unsaturated and saturated aldehydes.
