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: 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.
