ABSTRACT:
A process for the separation of ethanol from water using solvent extraction at elevated pressures is disclosed. Separation is effected by contacting aqueous ethanol with either propylene (propene), allene (propadiene), methyl acetylene (propyne), or methyl allene (1,2-butadiene). This produces two liquid layers which separate because of the difference in their densities, and are easily drawn off as separate streams. The solvent is recovered by reverse osmosis means in a liquid state. The ethanol and water remain in a liquid state and are substantially recovered.
