    Solvent Extraction of Ethanol from Aqueous Solutions Using Biobased Oils, Alcohols, and Esters
    (AOCS Press, 2006) Richard D. Offeman; Serena K. Stephenson; George H. Robertson; William J. Orts
    Distribution coefficients and separation factors were determined for the partitioning of ethanol and water from aqueous mixtures into several vegetable oils and their fatty alcohol and fatty ester derivatives. Castor oil, ricinoleyl alcohol, and methyl ricinoleate all show higher ethanol distribution coefficients, and similar or reduced separation factors, relative to other oils and derivatives studied here or reported by others. Of particular interest, ricinoleyl alcohol has an ethanol distribution coefficient 50% higher than that of oleyl alcohol, a commonly studied solvent for ethanol extraction from fermentation broths.
