Abstract: The present invention relates to a process for separating solvents from s olvent-containing hydrogenation product mixtures from a catalytic hydrogenat ion process, which mixtures contain a water-soluble hydrogenation product ha ving an alcohol, lactone, ether, lactam or amino group in a solvent which is immiscible or not fully miscible with water and has a boiling point below 1 00°C, characterized in that water is added to the hydrogenation product mixt ure and the solvent-containing phase is separated off and recirculated to th e hydrogenation.
