Abstract: The present invention relates to a process for separating off solvents from solvent-comprising hydrogenation outputs from a catalytic hydrogenation process, which comprise at least one water-soluble hydrogenation product having at least one alcohol, lactone, ether, lactam or amino group in a solvent which is immiscible or not completely miscible with water and has a boiling point below 100° C., wherein water is added to the hydrogenation output, the solvent-comprising phase is separated off and recirculated to the hydrogenation.

Abstract: Procedimiento para la separación de disolventes a partir de descargas de hidrogenación, que contienen disolventes, procedentes de un procedimiento de hidrogenación catalítico, que contienen un producto de la hidrogenación, soluble en agua, que presenta al menos un grupo alcohol, un grupo lactona, un grupo éter, un grupo lactama o un grupo amino, en un disolvente no miscible o no completamente miscible con agua con un punto de ebullición situado por debajo de los 100ºC, caracterizado porque se aporta agua a la descarga de la hidrogenación, se separa la fase que contiene el disolvente y se recicla hasta la hidrogenación.
