    摘要： The invention relates to a process for working-up a reaction mixture (5) comprising polyetherol and dissolved alkali metal comprising catalyst, wherein at least alkali metal ions of the dissolved alkali metal comprising catalyst are partially or completely removed from the mixture by a membrane separation process, the process comprising following steps: (a) feeding the reaction mixture (5) comprising polyetherol and dissolved alkali metal comprising catalyst into a first chamber (1) of a separation unit (3), (b) feeding a solvent into a second chamber (7) of the separation unit (3), the first chamber (1) and the second chamber (7) being separated by a membrane (9), (c) transporting at least the alkali metal ions of the alkali metal comprising catalyst from the first chamber (1) into the second chamber by passing through the membrane (9).

    摘要： A process continuously hydrogenating unsaturated compounds, in which particles of a first hydrogenation catalyst are suspended in a liquid phase in which an unsaturated compound is dissolved, the liquid phase, in the presence of a hydrogenous gas at a first partial hydrogen pressure and at a first temperature, is conducted through a packed bubble column reactor in cocurrent counter to the direction of gravity, the effluent from the bubble column reactor is sent to a gas-liquid separation, the liquid phase is sent to a crossfiltration to obtain a retentate and a filtrate, the retentate is recycled into the bubble column reactor and the filtrate, in the presence of a hydrogenous gas at a second partial hydrogen pressure and at a second temperature, is passed over a bed of a second hydrogenation catalyst, the second partial hydrogen pressure is at least 10 bar higher than the first partial hydrogen pressure.
