| titleOfInvention | System and method for continuously synthesizing mononitrotoluene in ultrasonic microreactor |
| abstract | Pure toluene is used as a raw material, mixed acid of fuming nitric acid and concentrated sulfuric acid is used as a nitrating agent, the pure toluene and the mixed acid are mixed in the microreactor through continuous conveying equipment, and ultrasound with specific frequency and power is applied at the same time. The cavitation of the ultrasound causes violent disturbance in the fluid, so as to strengthen the mixing between the fluids and improve the yield of the mononitrotoluene. The temperature of the reaction mixture is controlled to be 0-60 ℃, and the reaction residence time is 2-30 s. The invention shortens the synthesis reaction time of the mononitrotoluene (10-40 min in the prior art), realizes continuous production, and is easy to integrate and amplify in parallel. |
