The invention discloses a preparation method of quinocetone. The preparation method comprises that benzofurazan, acetylacetone and benzaldehyde as raw materials in the presence of magnetic magnesium-aluminum hydrotalcite solid alkali and alkaline quaternary ammonium salt as catalysts in anhydrous ethanol as a solvent undergo a reaction at a temperature of 10-100 DEG C for 1-10h, and then the reaction product liquid is treated to form quinocetone. Through use of the magnetic magnesium-aluminum hydrotalcite solid alkali catalyst, the preparation method has simple processes, can be operated easily, realizes easy product separation, has small environmental pollution, is suitable for industrial production with a certain scale and is a green and clean synthesis route.
