Method for preparing ketonic acid

The invention discloses a method for preparing ketonic acid, belonging to the technical field of deep processing of turpentine. The method comprises the following steps: firstly, putting alpha-pinene, ammonium sulfate and cetyl sodium sulfate into a reactor, adding water, stirring, subsequently adding potassium permanganate for reaction, performing suction filtration, collecting the filtrate and the filter cakes, washing the filter cakes with water, mixing a scrubbing solution with the filtrate, adjusting the pH value by using acid, extracting by using benzene, collecting a water layer, adjusting the pH value of the water layer by using alkali, and subsequently drying, concentrating, filtering and washing, thereby obtaining ketonic acid. As the method does not need rigorous production conditions, and the production environment and the equipment are easy to achieve, the production difficulty of ketonic acid is effectively alleviated, the production period is shortened, and the production cost is lowered.
