  • Hydroformylation process
    Patent number: 9067876
    Abstract: Disclosed is an improved exothermic hydroformylation process having at least two reaction stages. Cooling is provided by externally cooling a stream of reaction mixture from one of the stages, dividing the cooled stream into at least two cooled reaction mixture streams; transferring one cooled reaction mixture stream back into the same reaction stage from which it was removed to cool the reaction mixture in that reaction stage; and transferring at least one cooled reaction mixture stream(s) into and through heat exchange means that cool a different reaction stage, and returning it to the same reaction stage from which it was removed.
    Type: Grant
