| titleOfInvention | A method for preparing nitrosyl sulfuric acid in a microchannel reactor and its application |
| abstract | The invention provides a method for preparing nitrosyl sulfuric acid in a microchannel reactor and application thereof, and belongs to the technical field of dye intermediate synthesis. The present invention uses nitrosyl sulfuric acid solution as the reaction accelerator, which can speed up the reaction process and improve the reaction efficiency; the present invention performs the redox reaction of nitric acid and sulfur dioxide in the microchannel reactor, which can strengthen the mass transfer and heat transfer process of the reaction, and significantly The reaction time is shortened, thereby improving the product yield and the reaction efficiency; the present invention conducts the redox reaction of nitric acid and sulfur dioxide in the microchannel reactor, which can reduce the volume of the production reaction unit, reduce the instantaneous reaction amount in the production process, and realize nitrous The intrinsic safety of the acyl sulfate production process ensures the safe production of the enterprise. At the same time, the microchannel reactor occupies a small area, can realize the continuous production of nitrosyl sulfuric acid, can realize the accurate control of reaction parameters, and ensure the stability of product quality. |
