(1) Isopropylbenzene and a solid catalyst are added to a reactor and ultrasonicated to form a suspension; said solid catalyst is a nitrogen-doped carbon material, and said nitrogen-doped carbon material is nitrogen-doped carbon nanotubes, nitrogen-doped graphene, or nitrogen-doped activated carbon; the amount of nitrogen-doped carbon material doped is 2 to 4.0% by mass percentage; the weight ratio of said nitrogen-doped carbon material solid catalyst to isopropylbenzene is 0.006 to 0.012:1;
(2) the resulting suspension was heated to 40-100C, oxygen was passed in, and the reaction was carried out at atmospheric pressure for 1-12h; the oxidizing agent was passed in by bulging, and the flow rate of the oxygen was 0.5-1.5mL/min per mL of isopropylbenzene;
(3) after the reaction of step (2) was completed, the reaction mixture was separated, and the solid catalyst and a liquid mixture containing 2-phenyl-2-propanol, acetophenone and isopropylbenzene hydroperoxide;
(4) separating and purifying the liquid mixture in step (3) to obtain the target products 2-phenyl-2-propanol and acetophenone.
