| titleOfInvention | A kind of production device of 2-nitro-4-methylsulfonyl benzoic acid |
| abstract | The utility model discloses a production device for 2-nitro-4-methylsulfonyl benzoic acid. The device takes a high-pressure reaction kettle made of nitric acid corrosion-resistant materials as the main body, a reaction liquid preparation tank is connected in front of the device, and the upper part passes through a pipeline It is connected with the smoke absorber, and the smoke absorber is connected with the nitric acid concentrator through the pipeline; the lower part of the autoclave is connected with the washing separator through the pipeline, and a dryer is also connected behind the washing separator; this device will prepare 2-nitro-4 The nitrogen oxide gas produced by methylsulfonyl benzoic acid is absorbed by the smoke absorber to become dilute nitric acid, which is then processed by the nitric acid concentrator and recycled for use. The reaction product enters the washing separator, and the separated liquid is recycled together with the recovered nitric acid to obtain The product is dried; the equipment is simple, the process is safe and reliable, the product quality is stable, and the exhaust gas is discharged up to the standard, which conforms to the development direction of green chemical industry and the requirements of clean production. |
