Abstract:
1. The method for solubilising and separating carboxylic acids with a solubilizing compound from aqueous or organic solutions, emulsions, suspensions arising in medical therapy, medical analytics, food analytics, food processing, oil processing, oil analytics, fuel processing, modulation of chemical or physico-chemical reactions, solubilization of poorly solvable molecules, analytics in pharmaceutical or chemical industry or science, removal of carboxylic acids from sewage from private, commercial or industrial cleanings, removal of carboxylic acids from bioreactor processes, organogelation or nanoemulsification of carboxylic acids, wherein said solubilizing compound contains at least one amidino group and/or at least one guanidino group and wherein the solubilizing compound has a partition coefficient between n-octanol and water of K OW <6.30, and wherein the method comprises the following steps: i) providing the solution or emulsion or suspension containing the carboxylic acids; ii) adding of at least equimolar amounts of at least one solubilizing compound; iii) separating the solubilized carboxylic acids from the solution or emulsion or suspension by phase separation, filtration, nanofiltration, dialysis, absorption, complexation, electrophoresis, evaporation, distillation and/or extraction.
