NOVELTY - Preparation of 1,3-cyclohexanedione involves adding palladium graphene catalyst, and resorcinol dissolved in dichloromethane into reactor, introducing hydrogen gas, reacting at 20-60 degrees C for 0.5-3 hours under hydrogen pressure of 0.1-2 MPa, and post-treating the reaction solution. USE - Preparation of 1,3-cyclohexanedione (claimed). ADVANTAGE - The method enables simple preparation of 1,3-cyclohexanedione with high selectivity without using large amount of organic and inorganic salts.
