Abstract:
1. A process for recovering amyl alcohol from a product stream of an ethanol distillation apparatus, comprising: (a) conveying a first fluid stream from an ethanol distillation apparatus to an extractor, the first fluid stream consisting of a first fluid phase comprising amyl alcohol in admixture with an ethanol in water solution; (b) conveying a second fluid stream to the extractor, the second fluid stream being immiscible with the first fluid stream and consisting of a second fluid phase comprising at least one extractant solvent selected from the group consisting of an amyl alcohol and an amyl alcohol acetate; (c) contacting the first fluid phase with the second fluid phase in the extractor, thereby extracting the amyl alcohol from the first fluid phase into the second fluid phase; (d) separating the immiscible fluid phases; and (e) separating the extractant solvent from the second fluid phase.
