一种草除灵的合成方法
摘要：
一种草除灵的合成方法，涉及农用除草剂草除灵的生产工艺技术领域，本发明采用低温法，同时加入催化剂，反应温度由90～95℃降至60～65℃控制副产物的生成，提高生产安全性，含量达到98％，总收率大于80％。
摘要（英）：

The invention relates to a synthesis method of benazolin, belonging to the technical field of production process of the benazolin as an agricultural herbicide. The generation of side products is controlled by adopting a low-temperature method, adding a catalyst as well as reducing the reaction temperature from 90-95 DEG C to 60-65 DEG C. By adopting the invention, the production safety is improved, the content of the benazolin reaches 98 percent, and the total yield is more than 80 percent.
