Patent number: 8048655Abstract: A method is disclosed for the recovery of an organic acid from a dilute salt solution in which the cation of the salt forms an insoluble carbonate salt. A tertiary amine and CO2 are introduced to the solution to form the insoluble carbonate salt and a complex between the acid and an amine. A water immiscible solvent, such as an alcohol, is added to extract the acid/amine complex from the dilute salt solution to a reaction phase. The reaction phase is continuously dried and a product between the acid and the solvent, such as an ester, is formed.Type: GrantFiled: August 26, 2009Date of Patent: November 1, 2011Assignee: ZeaChem, Inc.Inventors: Dan W. Verser, Timothy J. Eggeman

Publication number: 20110229945Abstract: The present invention relates to a process for the production of a dicarboxylic acid. The process comprises fermenting a yeast in the presence of a carbohydrate-containing substrate and low amounts of oxygen at a pH value at which at least 50% of the dicarboxylic acid is in the acid form. The process of the present invention allows for high yields of the dicarboxylic acid product and is more cost-effective than existing processes in which the salt is produced which during recovery has to be converted to the acid. It also leads to a simpler and more convenient downstream processing.Type: ApplicationFiled: May 20, 2009Publication date: September 22, 2011Inventors: Mickel Leonardus August Jansen, René Verwaal
