use | triazine herbicides are selective pre-bud soil treatment agents. It is suitable for weeding in cotton fields, because of its poor leaching in the soil, rainfall or irrigation before and after application can increase its leaching capacity and exert its efficacy. When the content of organic matter in the soil is higher than 2%, the dosage must be appropriately increased. Used in cotton fields to control annual broad-leaved weeds, such as wild amaranth, purslane, Solanum nigrum, morning glory, quinoa, Xanthium, and yellow flower; gramineous weeds, such as barnyard grass, crabgrass, Dragon scratch grass, arm grass, etc., with an effective period of 30d. The general dosage is 15~22.5g/100 m2 of 80% wettable powder, 20~25g/100 m2 of weeding in seedling and transplanting fields, and there is serious drug damage when it exceeds 30g/100m2. |
production method | firstly, quizzing fluid is synthesized in the presence of solvent trichloroethylene, cyanuric chloride is quantitatively added, isopropylamine is added dropwise at 15 ℃, stirring for 30min after dropwise, ammonia water is controlled to be added dropwise at 15~20 ℃, pH value above 8, stirring for 30min, water is added for distillation, and solvent is recovered, cooling, discharging, suction and filtration, washing with water to exterminate fluid, yield> 92%, content ≥ 95%. Re-synthesis of isopropyl alcohol will be added dropwise to extinguish fluid, the reaction will be carried out in the presence of solvent, the temperature is not more than 15 ℃, the dropwise stirring will be 10min, liquid alkali will be added, the temperature will be raised to 35 ℃, the reaction will be 2h, the reaction will be completed, the reaction will be cooled and crystallized, centrifuged and dried with water to obtain isopropyl alcohol, the yield will be> 90%, and the content will be> 90%. ≥ |
