| titleOfInvention | Synthetic method of tetramethyluric acid and special catalyst thereof |
| abstract | The application discloses a synthetic method of tetramethyluric acid. The dimethyl carbonate, the ionized water and the catalyst are added into a reaction kettle, stirred and heated to 160 ℃, the preheated uric acid is added into the reaction kettle, the stirring speed is increased, and the reaction is started. The reaction conditions were: under the action of a catalyst, the temperature is 160-180 ℃, the pressure is normal pressure, and the reaction time is 3-4 hours. The catalyst is a ruthenium-containing catalyst. The invention realizes the synthesis of the tetramethyluric acid under normal pressure. In the production process, the energy consumption can be reduced, and the requirement on equipment is lowered. |
