Patent number: 9963414Abstract: The disclosed methods for preparing and isolating carboxylic esters ensure a high product purity and minimize technical complexity. These methods are based on the reaction of a carboxylic acid with an alcohol in an aqueous medium. In some examples, the alcohol is used both for the esterification and for the precipitation of the salts, preferably ammonium salts, formed in the synthesis.Type: GrantFiled: December 5, 2014Date of Patent: May 8, 2018Assignees: THYSSENKRUPP INDUSTRIAL SOLUTIONS AG, THYSSENKRUPP AGInventors: Markus Fritsch, Armin Börner, Ivan Shuklov, Zeljko Knez

Publication number: 20100129509Abstract: In a method for extracting products of value from animal or vegetable starting material, a solution is to be created, with which extraction is improved, with regard to both the yield and separation of natural products to be extracted, and management of the method. This is achieved in that soluble constituents are extracted from the starting material in a first extraction step, using CO2, and subsequently, in a second extraction step, other constituents are extracted with compressed hydrocarbons.Type: ApplicationFiled: June 13, 2008Publication date: May 27, 2010Inventors: Heribert Dierkes, Volkmar Steinhagen, Michael Bork, Christoph Lütge, Zeljko Knez
