Provided in the present application is a method for preparing vinylene carbonate, belonging to the technical field of organic synthesis, and can solve technical problems in existing vinylene carbonate preparation methods such as complex operation steps, long reaction time, easy equipment corrosion, high reaction temperature, and low yield. The present technical solution comprises: adding, into a reaction device, a certain mass of supported copper-based catalyst, ethylene carbonate and hydrogen receptor, and performing a catalytic dehydrogenation-hydrogenation coupling reaction in a nitrogen atmosphere at 200-300°C to prepare a vinylene carbonate product. The present application has the characteristics of simple preparation process, low cost, low reaction temperature, high yield, etc. The present application can be applied to the area of vinylene carbonate preparation. |
