    Abstract: A process is described for isomerizing pentenenitrile in a reactant stream, wherein the isomerization is effected over a heterogeneous catalyst in a distillation column in such a way that, during the isomerization of the isomerization reactant, it is distillatively depleted in relation to the isomerization product in the reaction column of the distillation column.

    Abstract: Procedimiento para la separación por extracción de catalizadores disueltos, homogéneos, a partir de una descarga de la reacción de una hidrocianuración de mononitrilos insaturados para dar dinitrilos, mediante extracción con ayuda de un hidrocarburo K, caracterizado porque a) se concentra por evaporación la descarga de la reacción como paso previo a la etapa b) mediante destilación a presiones comprendidas entre 0,1 y 5.000 mbares y a temperaturas comprendidas entre 10 y 150ºC, b) se aporta un hidrocarburo K a la descarga de la reacción, concentrada por evaporación, con lo que se obtiene una corriente I, y c) se alimenta la corriente I, sin separación previa de las fases líquidas, en un dispositivo de extracción y se extrae a una temperatura T con el hidrocarburo K, obteniéndose una corriente II que contiene el hidrocarburo K enriquecido con el catalizador, y una corriente III pobre en catalizador.

    Abstract: A process for extractively removing homogeneously dissolved catalysts from a reaction effluent of a hydrocyanation of unsaturated mononitriles to dinitriles with a hydrocarbon H, including performing the steps of a) concentrating the reaction effluent before step b) by distillation at pressures of from 0.1 to 5000 mbar and temperatures of from 10 to 150° C., b) adding a hydrocarbon H to the concentrated reaction effluent to obtain a stream I, and c) feeding stream I, without prior separation of the liquid phases, into an extraction apparatus and extracting it at a temperature T with the hydrocarbon H to obtain a stream II comprising the hydrocarbon H enriched with the catalyst and a stream III having a low catalyst content.
