  • PROCESS FOR PREPARING ALDEHYDES AND SEPARATION OF THE CATALYST SYSTEM BY MEMBRANE SEPARATION
    Publication number: 20220033337
    Abstract: The present invention provides a process for preparing aldehydes from C2 to C20 olefins using a subsequent membrane separation to separate the homogeneously dissolved catalyst system, wherein prior to the membrane separation a gas exchange that increases the partial pressure fraction of carbon monoxide or hydrogen is carried out in order to boost catalyst retention by the membrane.
