Synthesis method of cyclohexene oxide

The invention provides a synthetic method of cyclohexene oxide. The synthetic method comprises the following steps: mixing an active phase with a ligand to prepare a catalyst; mixing the catalyst with cyclohexene to obtain a mixed solution; adding a substrate into a reaction kettle, and preheating the reaction kettle; injecting the mixed solution and a cumyl hydroperoxide solution into a preheated reaction kettle, and carrying out heat preservation to obtain a reaction solution; extracting the reaction solution, and enabling the reaction solution to pass through a low-pressure steam heat exchanger; and mixing the reaction solution with a NaOH aqueous solution, conducting cleaning, and separating a liquid to obtain cyclohexene oxide. The synthesis method provided by the invention realizes coupling of two steps of synthesis of carboxylic acid peroxide and oxidation of cyclohexene, simplifies the technological process of cyclohexene oxide synthesis, and is mild in reaction condition, high in cyclohexene oxide se
