Abstract:
PROBLEM TO BE SOLVED: To provide a method for easily oxidizing a starting material, particularly an organic starting material, using an oxidant so as to obtain a product by a technically easy, economical method.
SOLUTION: The method for obtaining a product mixture containing cyclohexanol and cyclohexanone by oxidizing cyclohexane using an oxidant comprises a step of carrying out oxidation in a rectifying column, which has a bottom region at its lower end, a top region at its upper end and a reaction zone between the top and bottom regions and has a separation performance of 10-100 in terms of the number of theoretical plates, a step of maintaining the reaction mixture in a boiling state in the reaction zone, and a step of introducing the oxidant into the reaction zone in at least two sub-streams. Here, the oxidation is carried out under a condition wherein the average retention time of a reaction mixture on each plate of the column is 1-120 min and the number of theoretical plates in the upper region of the rectifying column is 5-50.
