Abstract

A process for producing allyl alcohol is disclosed. The process comprises reacting propylene, acetic acid, and oxygen to produce a reaction mixture. The reaction mixture is distilled to produce a vapor stream comprising propylene and a liquid stream comprising allyl acetate, acetic acid, acrolein, and allyl diacetate. The liquid stream is distilled to produce a lights stream comprising acrolein; a side draw comprising allyl acetate, acetic acid, and water; and a bottoms stream comprising acetic acid and allyl diacetate. The bottoms stream is distilled to remove a heavies stream comprising allyl diacetate. The side draw is hydrolyzed to produce allyl alcohol.
