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: 9371267Abstract: A method for preparation of secondary alcohols with a high proportion of hydroxyl group at the C2 position is disclosed. Alkyl carboxylates, high in alpha-methylcarboxylate content, are produced via reaction of an alpha-olefin and a carboxylic acid in the presence of a cerium catalyst. The resultant alkyl carboxylate is hydrolyzed to yield a secondary alcohol with a high 2-hydroxyl content. The secondary alcohol may be used to prepare esters, especially phthalate esters or cyclohexanoate diesters, which are useful as plasticizers. These esters are more effective as plasticizers than esters derived from other secondary alcohols due to their high C2 point of attachment.Type: GrantFiled: November 16, 2010Date of Patent: June 21, 2016Assignee: ExxonMobil Chemical Patents Inc.Inventors: Karla S. Colle, Allen D. Godwin

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.
