| titleOfInvention | A kind of preparation method of halogenated pyridine nitrogen oxides |
| abstract | The invention discloses a preparation method of halogenated pyridine nitrogen oxides. The method includes the following steps: (1) dissolving the raw material halopyridine in a solvent, adding a certain amount of oxidant, and reacting at a reaction temperature of 0-40°C, the reaction is completed, and a reaction product is obtained; (2) the step (1) The obtained reaction product is subjected to subsequent post-processing steps to obtain the target product halogenated pyridine nitrogen oxides. The preparation method of the invention has the advantages of low reaction temperature, high yield, high purity and low cost. |
