  • Process for the preparation and isolation of carboxylic esters
    Patent number: 9963414
    Abstract: 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: Grant
    Filed: December 5, 2014
    Date of Patent: May 8, 2018
    Assignees: THYSSENKRUPP INDUSTRIAL SOLUTIONS AG, THYSSENKRUPP AG
    Inventors: Markus Fritsch, Armin Börner, Ivan Shuklov, Zeljko Knez
