  • Hydroformylation of butenes
    Patent number: 8921607
    Abstract: Mixed butene streams containing butene-1 and isobutylene and optionally butene-2 are hydroformylated under conditions that hydroformylates all the monomers to yield a mixture of valeraldehydes. Higher temperatures and/or longer residence times and/or higher partial pressure of carbon monoxide than in conventional processes are used to ensure hydroformylation of all the monomers.
    Type: Grant
    Filed: April 4, 2012
    Date of Patent: December 30, 2014
    Assignee: ExxonMobil Chemical Patents Inc.
    Inventors: Raphael F. Caers, Eddy Theophile Van Driessche, Hubertus J. Beckers, Luc Roger Marc Martens, Georges Marie Mathys, John Richard Shutt
