Abstract: The invention provides a process for the purification of alcohols, particularly for the purification of isopropyl alcohol. A invention provides a process for reducing the amount of ultraviolet light absorbing ketone impurities and/or aldehyde impurities in a fluid mixture containing an alcohol in addition to ketone impurities and/or aldehyde impurities, which comprises reacting a fluid mixture containing an alcohol in addition to ketone impurities and/or aldehyde impurities, with a sufficient amount of a reducing agent, under conditions wherein the reducing agent is preferentially more reactive with the ketone impurities and/or aldehyde impurities than the alcohol to thereby form a reaction product; and then recovering a recovered alcohol product from the reaction product.
