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. Colle, Philippe L. Buess, Eddy T. Van Driessche, Allen D. Godwin, Ramzi Y. Saleh, Jon E. R. Stanat, Raphael F. Caers

Patent number: 8742192Abstract: The conversion and run length for oligomerization of olefins over a molecular sieve catalyst in a tubular reactor is improved by controlling the peak temperature to not exceed 50 degrees C. above the temperature of the temperature control fluid exiting the shell side outlet of the reactor. A tubular reactor containing molecular sieve catalyst is provided with a multipoint thermocouple in at least one tube, and optionally with a bottom design adapted for fast unloading of the molecular sieve catalyst from the tubular reactor.Type: GrantFiled: June 16, 2006Date of Patent: June 3, 2014Assignee: ExxonMobil Chemical Patents Inc.Inventors: John S.

Patent number: 8653184Abstract: Esters of cyclohexane polycarboxylic acids are used as plasticisers for polyvinyl chloride to enable products with comparable mechanical properties to be obtained using less polyvinyl chloride. Use of these esters also produces formulations with increased stability to ultra-violet light, improved low temperature properties, lower viscosity and improved processability as well as reduced smoke on burning. The esters of cyclohexane polycarboxylic acids may be used alone or in admixture with other plasticisers when the esters of cyclohexane polycarboxylic acids may act as viscosity depressants. Fast fusing plasticisers may also be included. The formulations and processes of making these formulations are particularly useful in the production of a range of goods from semi-rigid to highly flexible materials and are particularly useful in the production of medical materials, toys, and food contact articles.Type: GrantFiled: August 30, 2012Date of Patent: February 18, 2014Assignee: ExxonMobil Chemical Patents Inc.Inventors: Claudius P. Gosse, Thomas M. Larson, Pierre J. P. Legrand, Raphael F. Caers, Paul H. Daniels, Allen D. Godwin, Didier Naert

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.

Publication number: 20110313090Abstract: An improved method for producing di-isotridecylphthalate (DTDP) is disclosed by esterification using a tetra-alkyl titanate catalyst made from preferably primary alcohols having at least 4 and preferably up to but not more than 10 carbon atoms. In the esterification process, compared to using tetra-isopropyl titanate catalyst, less of the alcohol from the catalyst contributes to the environmental burden associated with discarding the waste water byproduct, and more is incorporated into the prime DTDP product.Type: ApplicationFiled: November 16, 2009Publication date: December 22, 2011Inventors: Nicolaas A.

Patent number: 7880046Abstract: Water reacts on molecular sieve catalysts used in oligomerization reactions and forms oxygenated compounds, in particular organic acids that may cause corrosion problems downstream of the reactor, in particular in distillation tower overhead systems and downstream thereof. A lowering of the presence of water in the feed prior to contacting thereof with the molecular sieve brings a significant reduction in corrosion downstream. At the same time, it has a significant beneficial effect on catalyst activity and brings a significant extension of catalyst life. Lowering water in the feed is particularly effective when organic nitrogen-containing Lewis bases are present in the feed, even at low levels.Type: GrantFiled: June 16, 2006Date of Patent: February 1, 2011Assignee: ExxonMobil Chemical Patents Inc.Inventors: John S.

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.
