ABSTRACT:
Process for extracting organic compounds which are present in water in the form of solutions or suspensions by a liquid carboxylic acid which is immiscible with water. Branched or unbranched linear acids such as n-heptanoic, n-octanoic, or 2-ethylhexanoic acids make it possible to quantitatively extract compounds such as phenols, amines or amino acids from such aqueous solutions, thereby rendering the process useful for the purification of industrial wastewaters.
