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: 8791306Abstract: In a process for oxidizing an alkylaromatic compound to the corresponding hydroperoxide, a feed comprising an alkylaromatic compound is contacted with an oxygen-containing gas in the presence of a catalyst comprising a cyclic imide. The contacting is conducted at a temperature of about 90° C. to about 150° C., with the cyclic imide being present in an amount between about 0.05 wt % and about 5 wt % of the alkylaromatic compound in the feed and the catalyst being substantially free of alkali metal compounds. The contacting oxidizes at least part of the alkylaromatic compound in said feed to the corresponding hydroperoxide.Type: GrantFiled: May 28, 2013Date of Patent: July 29, 2014Assignee: ExxonMobil Chemical Patents Inc.Inventors: Jihad M.

Patent number: 8669311Abstract: C7-C12 secondary alcohol esters of cyclohexanecarboxylic acids are especially useful as plasticizers for PVC and other plasticizable polymers. In embodiments, these plasticizers are useful in plastisol formulations to help improved processability of flexible PVC material. In other embodiments these same plasticizers can be used in blends with other plasticizers to improve processability. In preferred embodiments these same plasticizers can be used to prepare flexible PVC compounds with enhanced low temperature flexibility, low toxicity, and improved resistance to outdoor aging.Type: GrantFiled: October 23, 2008Date of Patent: March 11, 2014Assignee: ExxonMobil Chemical Patents Inc.Inventors: Karla S.

Patent number: 8586496Abstract: A method is described for preparing a molecular sieve-containing catalyst for use in a catalytic process conducted in a stirred tank reactor. The method comprises providing a mixture comprising a molecular sieve crystal and forming the mixture into catalyst particles having an average cross-sectional dimension of between about 0.01 mm and about 3.0 mm. The mixture may include a binder and the catalyst particles are then calcined to remove water therefrom and, after calcination and prior to loading the catalyst particles into a reactor for conducting the catalytic process, the catalyst particles are coated with a paraffin inert to the conditions employed in the catalytic process.Type: GrantFiled: June 19, 2009Date of Patent: November 19, 2013Assignee: ExxonMobil Chemical Patents Inc.Inventors: Carolyn B.
