Patent number: 9546259Abstract: 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 plasticizers if before esterification with glycerol, an aryl acid is introduced together with the aliphatic acids.Type: GrantFiled: April 16, 2014Date of Patent: January 17, 2017Assignee: ExxonMobil Chemical Patents Inc.Inventors: Karla S.

Patent number: 8541627Abstract: An improved hydroformylation catalyst cycle is disclosed wherein the cobalt catalyst is recycled to the hydroformylation reaction mainly as a water soluble carbonyl salt, obtained from extraction of the acidic form of the homogeneous cobalt carbonyl catalyst from the hydroformylation product with an aqueous solution of a salt of a weaker acid. The organic product after extraction is submitted to a further demetalling step in the presence of a dilute acid and an oxidant. The water from this further demetalling step is suitable for use in the upstream extraction step. A free water phase present in the hydroformylation reaction product may be separated upstream from the extraction step and is suitable for use in the further demetalling step, such that the catalyst cycle has no waste water stream.Type: GrantFiled: August 19, 2009Date of Patent: September 24, 2013Assignee: ExxonMobil Chemical Patents Inc.Inventors: Eddy T. A. Van Driessche, Ronald D. Garton, Corey W. Reed

Patent number: 8476476Abstract: In the hydroformylation of C5-C14 olefins with cobalt catalyst to produce C6-C15 oxygenates, where offgasses from the hydroformylation or cobalt removal step contain volatile cobalt compounds, the cobalt compounds are recovered by scrubbing the offgas with a liquid, and recycling the liquid to the cobalt removal step. Suitable scrubbing liquids are the organic cobalt-depleted hydroformylation reaction product or a downstream derivative thereof, or an aqueous solution of a Co2+ salt, preferably such salt of formic acid.Type: GrantFiled: August 19, 2009Date of Patent: July 2, 2013Assignee: ExxonMobil Chemical Patents Inc.Inventors: Eddy T.

Patent number: 8247618Abstract: Oxidative recovery methods that use oxygen or air for recovery of homogeneous metal catalysts, such as cobalt catalysts, used in for example hydroformylation processes, can be hazardous. Explosive or flammable gas mixtures may be generated inside the process equipment, which can deflagrate upon any ignition source such as a static electricity discharge. The use of a flammable diluent has been found to be a very effective way of optimizing the recovery method, by bringing the resulting gas mixtures above their upper flammability limit. The offgas produced is then also easier to dispose of as a fuel, as compared to when a non-flammable diluent is used.Type: GrantFiled: March 31, 2008Date of Patent: August 21, 2012Assignee: ExxonMobil Chemical Patents Inc.Inventors: Kenneth J. Buturla, James T. Ritchie, Ronald D. Garton, Eddy T. A. Van Driessche

Patent number: 7910782Abstract: In a hydroformylation reaction, the circulation and recovery of cobalt carbonyl in a cobalt catalyst cycle using carbonylate as an intermediate and acidification thereof, is improved by supplying an aqueous sulfuric acid solution containing less than 16% wt of sulfuric acid to the carbonylate to control sulfuric acid concentration in the carbonylate/acid mixture, before accounting for any acid consuming reaction, to a value of from 2% to 10% by weight. Single step and multistage liquid/liquid extraction techniques as well as vapor/liquid extraction techniques followed by the absorption of cobalt from the vapor in an organic liquid both benefit from this improvement.Type: GrantFiled: March 28, 2008Date of Patent: March 22, 2011Assignee: ExxonMobil Chemical Patents Inc.Inventors: Eddy T.

Patent number: 7081553Abstract: The Cobalt Flash Process is modified by replacing formic acid with acetic acid as process acid. Efficiency using acetic acid as process acid is achieved by two improvements which may be added separately and independently: (1) separation of acetic acid and water from the condensate distilled off in the cobalt salt concentration stage; and (2) removal of formic acid from the system by reaction with the product alcohol in the preformer.Type: GrantFiled: March 28, 2003Date of Patent: July 25, 2006Assignee: ExxonMobil Chemical Patents Inc.Inventors: Dominic T.
