ABSTRACT:
In a process for the extraction of organic compounds contained in an aqueous solution of non-ionic surfactants which contain the organic compounds to be extracted, the aqueous solution is intensely mixed with a liquid which is not miscible with water whereby the organic compounds transfer to the liquid which is not miscible with water, and the blend of the aqueous solution and the liquid which is not miscible with water is then separated, the mixing and the separation process being performed in a centrifugal extractor.
