| titleOfInvention | A kind of casalan synthesis process and its reaction kettle |
| abstract | The invention relates to and discloses a casalan synthesis process and a reaction kettle, which comprises the following steps: S1, salt-forming reaction, crystallization suction filtration, drying: pumping toluene into two reaction kettles respectively by a metering pump, and each The reaction kettle was poured into salicylamide and sodium hydroxide in turn, stirred, opened the steam valve, controlled the steam pressure, heated up and refluxed for dehydration, after the dehydration was completed, opened the jacket circulating water to cool down to 40 ° C, and then transferred to a three-in-one oven for suction filtration, Then turn on the hot water in the jacket, raise the temperature to 60°C, and evacuate to no higher than 0.09MPa. The filtered toluene mother liquor and the reclaimed toluene solution of the baking material are directly fed and applied mechanically. The present invention adopts a series of steps such as salt-forming reaction, crystallization suction filtration, drying, dissolving, ring-forming reaction, distillation, vacuum distillation, water washing, filtration, drying, dissolving, pressure filtration, crystallization centrifugation, rinsing, centrifugation and drying, etc. step, casalan can be synthesized at lower cost. |
