摘要： A method and a system for inexpensively producing a corresponding target ketone and/or alcohol by decomposing hydroperoxide rapidly and with high selectivity using an aqueous alkaline solution and by recovering and recycling alkali. The method includes neutralizing at least a part of a carboxylic acid in the oxidation reaction solution by contacting the oxidation reaction solution with a first alkaline solution including a carbonate of an alkali metal, and separating the reaction mixture into a first oil phase and a first water phase; decomposing the hydroperoxide and the ester compound in the first oil phase by contacting the first oil phase with a second alkaline solution having a higher pH value than the first alkaline solution, and separating the reaction mixture into a second oil phase and a second water phase; and recovering the carbonate of an alkali metal from the first water phase and recycling the carbonate of an alkali metal to the first alkaline solution.
