  • 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

  • Isobutylene
    Patent number: 7935851
    Abstract: High purity isobutylene streams are obtained by the hydroformylation of mixed butene streams containing butene-1 and isobutylene (and optionally butene-2) under conditions that hydroformylate primarily butene-1 to yield a mixture of valeraldehyde and isobutylene, which may be separated out as an enriched isobutylene stream and used in the production of methyl tertiary butyl ether, tertiary butyl alcohol, di-isobutylene or polyisobutylene.

  • Polyol Ester Plasticizers and Process of Making the Same
    Publication number: 20110021680
    Abstract: Triglyceride and other polyol ester PVC plasticizers can be produced by recovery of branched C6 to C9 aldehydes from a hydroformylation product, optional hydrogenation to the alcohol, oxidation to the acid with oxygen and/or air, recovery of the resulting acid, and esterification with glycerol, ethylene glycol, propylene glycol or mixtures thereof. The branched alkyl chains comprise at least 10% methyl branching. Special triglycerides are derived from branched aliphatic acids having alkyl chains with average carbon numbers from 6 to 9 and at least 10% methyl branching. These triglycerides are fast fusing plasticisers if before esterification with glycerol, an aryl acid is introduced together with the aliphatic acids.
