摘要： A process for recovering butanol from a mixture comprising a water-immiscible organic extractant, water, butanol, and optionally a non-condensable gas, is provided. The butanol is selected from 1-butanol, 2-butanol, isobutanol, and mixtures thereof. An overhead stream from a first distillation column is condensed to recover a mixed condensate. An entrainer is added to at least one appropriate process stream or vessel such that the mixed condensate comprises sufficient entrainer to provide phase separation of the organic and the aqueous phases to provide for recovery of the butanol.

摘要： A process for recovering butanol from a mixture comprising a water-immiscible organic extractant, water, butanol, and optionally a non-condensable gas, is provided. The butanol is selected from 1-butanol, 2-butanol, isobutanol, and mixtures thereof. The extractant comprises at least one solvent selected from the group consisting of C7 to C22 fatty alcohols, C7 to C22 fatty acids, esters of C7 to C22 fatty acids, C7 to C22 fatty aldehydes, and mixtures thereof.
