| 在氧化釜中加入百草枯母液和滤饼,搅拌并冷却至15℃左右,缓慢通入氯气,控制通氯速度使反应温度维持在20—30℃.固体逐渐消失,颜色由紫褐色转褐色,最后变酒红色.通氯时间约一小时,PH2左右.停止通氯,搅拌半小时,得粗百草枯,含量 43%左右. |

Ref. only: The mother liquid and the filter cake of the paraquat were added into the oxidation reactor. After cooling down to ca. 15C while stirring, chlorine gas was slowly introduced by controling the flow rate to keep the reaction temperature at ca. 20-30C. During this process, the solid gradually disappeared, and the color of the reaction mixture gradully turned from purple brown into brown, and finally into wine red. After ca. 1 hr chlorine introduction, the pH of the reaction mixture reached to 2. Stop chlorine introduction and further stirring for 0.5 hr gave crude (raw) paraquat with the yield of ca. 43% |
