  • Process for preparing Caldehydes
    Patent number: 11840506
    Abstract: A process for preparing C5 aldehydes involves hydroformylation of butenes with synthesis gas in the presence of a homogeneous catalyst system and a solvent. It is a feature of the process that the aldehyde concentration in the reaction mixture is limited.
    Type: Grant
    Filed: May 2, 2023
    Date of Patent: December 12, 2023
    Assignee: Evonik Operations GmbH
    Inventors: Dirk Fridag, Johannes Knossalla, Alexander Brächer, Peter Kucmierczyk, Anna Chiara Sale, Robert Franke, Ana Markovic
  • Optimized thermal separation by prior gas exchange
    Patent number: 11834399
    Abstract: A process can be used for preparing aldehydes from C2 to C20 olefins with a subsequent thermal separation for removal of the aldehyde formed. The process involves a membrane separation, which is preceded by performance of a gas exchange by which the proportion of the partial pressure represented by carbon monoxide or hydrogen is increased in order to reduce catalyst losses.

  • Process for preparing aldehydes and separation of the catalyst system by membrane separation
    Patent number: 11396488
    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.
