  • Process for preparing aldehydes and cooling a stream of matter
    Patent number: 11773041
    Abstract: A process for preparing aldehydes by a homogeneously catalyzed hydroformylation of C4 to C20 olefins involves withdrawing a biphasic stream (liquid/gaseous) and expanding in two stages. Before, between, or after the two stages, the liquid phase is cooled. Only after expansion and cooling is the homogeneously dissolved rhodium catalyst system separated from the residual stream in a three-stage removal.
