| titleOfInvention | Method for synthesizing refined metolachlor-imine by heterogeneous catalytic reaction rectification |
| abstract | The invention discloses a method for synthesizing refined metolachlor-imine by heterogeneous catalytic reaction rectification, comprising the following steps: 1) 2-methyl-6-ethylaniline, methoxyacetone and band The aqua is sent into the reactive distillation column; 2) the tower still is heated by the heating reboiler, and the reactive distillation is carried out under normal pressure or negative pressure to generate (fine) metolachlor-imine and water; 3 ) the water in the raw material and the water that the reaction produces is brought out azeotropically with the water-carrying agent, condensed and layered in the reflux water separation device, the organic layer of the upper stratum is circulated in the reactive distillation column, and the water phase of the lower stratum is discharged; the reaction product ( Essence) metolachlor-imine falls into the tower still, and continuously discharges from the lower part of the tower still. The invention adopts catalytic reaction rectification and adds water-carrying agent, which can not only remove the moisture in the raw materials, but also improve the conversion rate and yield of the reaction, and at the same time, the molecular sieve loaded with phosphotungstic acid is used as a catalyst to avoid equipment corrosion and damage. Environmental pollution. |
