  • Hydroformylation of butenes comprising isobutylene
    Publication number: 20070112220
    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: Application

    Inventors: Raf Caers, Eddy Van Driessche, Huub Beckers, Luc Martens, Georges Mathys, John Shutt
  • Organic compounds and processes for their manufacture
    Patent number: 6307093
    Abstract: Esters of branched C9 alcohols suitable as plasticizers are formed by esterification of a C9 alcohol produced by the aldol condensation from propanal and a C6 aldehyde and hydrogenation, the propanal optionally having been made from natural gas streams.
    Type: Grant
    Filed: November 24, 1999
    Date of Patent: October 23, 2001

  • Organic compounds and processes for their manufacture
    Patent number: 6090986
    Abstract: Esters of branched C.sub.9 alcohols suitable as plasticizers are formed by esterification of a C.sub.9 alcohol produced by the aldol condensation from propanal and a C.sub.6 aldehyde and hydrogenation, the propanal optionally having been made from natural gas streams.
    Type: Grant

    Assignee: Exxon Chemical Patents Inc.
    Inventors: Allen David Godwin, Richard Henry Schlosberg, Frank Hershkowitz, Michael G. Matturro, Gabor Kiss, Kirk Christian Nadler, Philippe Louis Buess, Richard C. Miller, Paul William Allen, Harry William Deckman, Raf Caers, Edmund John Mozeleski, Robert P Reynolds, Francis Joseph Healy
  • Minimizing cobalt catalyst loss in the production of alcohols by hydroformylation of olefins
    Patent number: 5130107
    Abstract: Cobalt is recovered from the oil/water mixed reaction product of oxonation by increasing the carbon dioxide level in the reaction product and adjusting the temperature to enhance the carbon dioxide level in the oil water phase to promote the formation of cobalt carbonate which is allowed to settle and may be removed and/or recycled increasing cobalt utilization and reducing environmental problems.
