| titleOfInvention | Aqueous synthesis process of nicosulfuron-methyl |
| abstract | The invention relates to the technical field of pesticides, and proposes a nicosulfuron-methyl aqueous phase synthesis process, comprising the following steps: S1, feeding: adding 2-ethoxycarbonylaminosulfonyl-N,N-dimethylnicotinamide to a reaction kettle , 2-amino-4,6-dimethoxypyrimidine, phase transfer catalyst, solvent, start stirring; S2, reaction: temperature 60～100 ℃, reaction 5～7 hours; S3, discharge: centrifuge, oven dry , to obtain nicosulfuron. Through the above technical solutions, the problems of complicated processes and poor product quality in the prior art are solved. |
