| titleOfInvention | Method for synthesizing para-xylene with high conversion and high selectivity from toluene and DMC |
| abstract | The invention discloses a method for synthesizing p-xylene with high conversion rate and high selectivity from toluene and DMC, and relates to the technical field of organic synthesis. The ratio is 1-2:1, the reaction temperature is 230-280°C, and the mass space velocity is 5-20h -1 . The present invention prepares a new type of catalyst and uses it to synthesize p-xylene from toluene and dimethyl carbonate, and realizes the new application of the prepared catalyst in the reaction; meanwhile, the present invention significantly reduces the reaction temperature through the application of the prepared catalyst And shorten the reaction time, and improve the conversion rate of toluene and the selectivity of p-xylene, thereby improving the yield of p-xylene, and the yield of p-xylene can reach more than 60%. |
