| titleOfInvention | Method for synthesis of chlorpyrifos |
| abstract | The present invention relates to a method for synthesis of chlopyrifos. The method of the present invention comprises the following steps: (1) dissolving 1/2-1/3 of a catalyst in water to adopt as a solvent; (2) adding sodium 3,5,6-trichloropyridin-2-olate to the solvent, and adding the remaining catalyst; and (3) adding an ethyl chloride to carry out a reaction to prepare the chlorpyrifos, wherein the resulting solvent after the reaction is subjected to a purification treatment, and is recycled. According to the present invention, the solvent can be recycled after precipitation cooling, such that the characteristics of energy saving, environmental protection, simpleness and reliability are provided; the yield is high, the production cost is low, and the method has a good industrial application prospect. |
