Summary:According to the present invention, there is provided a method for producing a ketone and/or an alcohol at high yield. The method includes the steps of mixing an oxidation reaction solution, which is obtained by oxygenating a hydrocarbon compound with molecular oxygen, and water, and separating the oxidation reaction solution into an oil phase that includes a hydroperoxide and an aqueous phase that includes a carboxylic acid; concentrate the aqueous phase to obtain a concentrated solution that includes the carboxylic acid and recover water; removing the carboxylic acid from the water recovered in the concentration stage; recirculate the water, from which the carboxylic acid has been removed, to the separation stage; and decomposing the hydroperoxide in the oil phase to give a ketone and/or an alcohol. (Machine-translation by Google Translate, not legally binding) Según la presente invención, se proporciona un método para producir una cetona y/o un alcohol a alto rendimiento. El método incluye las etapas de mezclar una solución de reacción de oxidación, que se obtiene oxigenando un compuesto hidrocarbonado con oxígeno molecular, y agua, y separar la solución de reacción de oxidación en una fase oleosa que incluye un hidroperóxido y una fase acuosa que incluye un ácido carboxílico; concentrar la fase acuosa para obtener una solución concentrada que incluye el ácido carboxílico y recuperar agua; retirar el ácido carboxílico del agua recuperada en la etapa de concentración; recircular el agua, de la que se ha retirado el ácido carboxílico, a la etapa de separación; y descomponer el hidroperóxido en la fase oleosa para dar una cetona y/o un alcohol.
