| titleOfInvention | Method for preparing and synthesizing 3,3',5,5' -tetramethyl-4, 4' -biphenyl diquinone by ultrasonic rapid method |
| abstract | The invention discloses a method for preparing and synthesizing 3,3',5,5' -tetramethyl-4, 4 '-biphenyl diquinone by an ultrasonic rapid method, which adopts 2, 6-dimethylphenol as a raw material for the first time, adds a copper-amine complex catalyst under the condition that alcohol and water are used as solvents, and dropwise adds hydrogen peroxide as an oxidant at a certain speed within a certain time, controls the reaction temperature and the pH value to carry out ultrasonic reaction, and can rapidly obtain an oxidative coupling product 3,3',5,5 '-tetramethyl-4, 4' -biphenyl diquinone after the reaction for a period of time. |
