Abstract
A method for preparing isopropyl alcohol including: feeding a feed stream containing a propylene monomer and water to a reaction unit, where the propylene monomer and the water react to form a reaction product containing isopropyl alcohol, the propylene monomer, and the water; feeding each of a first discharge stream and a second discharge stream discharged from the reaction unit to a stripper, where the first discharge stream contains a vapor-phase reaction product, which is condensed through a first heat exchanger and fed to the stripper in a liquid-phase, and wherein the second discharge stream contains a liquid-phase reaction product; and separating a top discharge stream and a bottom discharge stream from the stripper, wherein the top discharge stream contains the propylene monomer and the bottom discharge stream contains the water and the isopropyl alcohol.
