| titleOfInvention | A low-temperature continuous reactor and working method for producing diazonium compounds |
| abstract | The invention proposes a low-temperature continuous reactor and a working method for producing diazonium compounds, comprising a reaction flask and an overflow kettle, the reaction flasks have two, the output end of the first reaction flask is connected with the input end of the peristaltic pump, the second The output end of the reaction bottle is connected with the input end of the plunger pump, and the input end of the peristaltic pump and the input end of the plunger pump are connected in series with the overflow kettle. In the present invention, aromatic amine is used as the starting material, a solvent is used to prepare a solution or a uniform mixture, and the solution of sodium nitrite is pumped in a small-volume overflow kettle reactor, and the continuous feeding is carried out in an equivalent amount reaction, and after the reaction The raw material is continuously introduced into the acetic acid solution of sulfur dioxide through the overflow pipeline, and the product is obtained through extraction and concentration, and the total yield is as high as 80%. |
