ABSTRACT:
A process is presented for extracting polar organic compounds, in particular lower aliphatic alcohols, out of their aqueous solutions, which is based on the use of fluids which contain a significant amount of polyoxaalkanols, polyoxaalkanediols and/or polyoxaalkanepolyols. These compounds, by virtue of their high molar masses, their low solubility in water and their good affinity for polar organic compounds, are particularly suitable for use as extractants.
