| titleOfInvention | A kind of processing method of p-fluorobenzaldehyde |
| abstract | The invention discloses a processing method and processing equipment for p-fluorobenzaldehyde, comprising the following steps: adding synthetic materials into a raw solvent, stirring and reacting inside a reaction kettle, and transferring the obtained liquid to the inside of a precipitation box through a rotating heat dissipation pipe for cooling , after the liquid temperature reaches room temperature, precipitation is carried out and the inorganic salts in the liquid are adhered and separated, and then the filtrate is subjected to rectification and separation to obtain p-fluorobenzaldehyde. The internal liquid is fully mixed and reacted by stirring the reaction kettle, and the liquid is heated. The rotating heat dissipation pipe is dissipated through the heat dissipation bin, and the water vapor is regularly sprayed from the water tank installed inside the rotating heat dissipation pipe to physically cool the rotating heat dissipation pipe. Cooling, the heat exchange tube and water placed in the cooling tank inside the sedimentation tank are used to cool the liquid inside the sedimentation tank again, and the sedimentation work is carried out in the process of the liquid cooling zone through the sedimentation net to improve the production efficiency of p-fluorobenzaldehyde. The liquid is subjected to rectification and purification. |
