Patent number: 8143459Abstract: Oxo-alcohols in the plasticizer range typically contain small amounts of methyl esters having the same alkyl chain as the alcohol itself. These methyl esters are causing product quality problems and environmental problems because of transesterification in the esterification process where the plasticizer ester derivatives are produced. A process using controlled oxonation and hydrogenation conditions is disclosed for the production of alcohols containing low amounts of methyl esters. Plasticizer esters with low amounts of aliphatic di-alkyl esters are also disclosed.Type: GrantFiled: April 26, 2010Date of Patent: March 27, 2012Assignee: ExxonMobil Chemical Patents Inc.Inventors: Eddy Van Driessche, Jean-Jacques G.

Patent number: 7381853Abstract: A method of making a higher olefin product from a C4+ fraction separated from the hydrocarbon product produced by an oxygenate to olefin reaction unit. The C4+ fraction primarily contains butenes which may be directed to a higher olefin reaction unit without removing isobutenes, butanes, and/or butadiene. The C4+ fraction is particularly well suited for the production of higher olefins because of its high olefin content, low branching number, and low contaminent levels. The invention is also directed to an olefin product composition that is produced by contacting the C4+ fraction with an oligomerization catalyst. The olefin composition is characterized by a relatively high octene content, and octene with a branching number less than 1.4.Type: GrantFiled: February 22, 2005Date of Patent: June 3, 2008Assignee: ExxonMobil Chemical Patents Inc.Inventors: Luc R. M. Martens, John Stephen Godsmark, Marcel J. Janssen, Georges M. K. Mathys, Raphael F. Caers, Hubertus J. Beckers, J. Richard Shutt, Eddy Van Driessche

Publication number: 20070282134Abstract: Increasing the propylene content of the propylene feed delivered to a continuous hydroformylation process from the 95 mole % maximum level that is usual in typical chemical grade propylene to at least 97 mole %, for example to the 97.5% level obtainable from the conversion of oxygenates to olefins or the 99.5% level of polymer grade propylene, enables adjustments to be made in the syngas feed to the process. This leads to surprising improvements in hydroformylation product yield, in reactor capacity utilization and in the reduction of amounts of waste gases.Type: ApplicationFiled: January 28, 2005Publication date: December 6, 2007Inventors: Raphael Caers, Eddy Van Driessche
-
Publication number: 20070161829Abstract: The use of a controlled amount of water in a hydrogenation stage of the oxo process for the production of alcohols which uses at least two reactors in series improves the efficiency of the hydrogenation reaction and catalyst life as does a reduction in the amount of sulphur, chlorine and hydroformylation catalyst residues in the feed to hydrogenation.Type: ApplicationFiled: December 16, 2004Publication date: July 12, 2007Inventor: Eddy Van Driessche

Publication number: 20070112220Abstract: 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: ApplicationFiled: September 17, 2004Publication date: May 17, 2007Inventors: Raf Caers, Eddy Van Driessche, Huub Beckers, Luc Martens, Georges Mathys, John Shutt

Patent number: 6994799Abstract: Disclosed are ester-containing fluid compositions, methods of making such compositions, and methods of using such compositions. The fluid compositions comprise a mix of branched and linear ester compounds, and the fluid compositions are characterized by certain performance limitations.
