Abstract:
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.

Claim (Index 9):
A system for producing a ketone and/or alcohol by decomposing a hydroperoxide and an ester compound in an oxidation reaction solution obtained from oxidizing the hydrocarbon compound with molecular oxygen, in which the ketone and/or alcohol has the same number of carbon atoms as the hydrocarbon compound; wherein the system comprises:\n a neutralization unit for 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 comprising a carbonate of an alkali metal, and separating the reaction mixture into a first oil phase and a first water phase; a saponification unit for 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; an unreacted hydrocarbon recovery unit for recovering at least a part of an unreacted hydrocarbon from the second oil phase; a purification unit for obtaining the ketone and/or alcohol from the second oil phase after recovering at least a part of the unreacted hydrocarbon by purification; and an alkali recovery unit for 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.
