method for solubilizing and separating one or a plurality of carboxylic acids and use of a demobilized solubilizing compound

摘要

Patent Application: "Method for solubilizing and separating one or a plurality of carboxylic acids and use of a demobilized solubilizing compound". The present invention relates to a method for solubilizing and separating one or a plurality of carboxylic acids or carboxylic acid derivatives from an aqueous or organic solution, emulsion or suspension, comprising the following steps: (i) preparing the solution or emulsion or suspension with carboxylic acid or carboxylic acid derivatives; (ii) adding an amount of a solubilizing compound, in particular arginine or arginine derivative, to the solution, suspension or emulsion in the presence of a minimum amount of water, a demobilized solubilizing compound being used as a solubilizing compound; (iii) separating the solubilized carboxylic acids or carboxylic acid derivatives as a carboxylic acid phase or a carboxylic acid derivative phase from the solution or emulsion or suspension; and (iv) preferably reganking at least a portion of the solubilizing compound or a portion of a solubilizing compound derivative, in particular arginine or arginine derivative, of the solubilized and separated carboxylic acid phase or carboxylic acid derivative phase.
