【摘要】 为了解决目前国内使用的农药存在高毒,高残留的问题,开发了一种低毒,高效的一种新型农药四氟丙酸钠。根据合成工艺的路线选择,四氟乙烯与氰化钠在水和水溶性有机溶剂组成的反应体系中进行亲核加成反应,继而在碱性介质中水解生成四氟丙酸钠的合成工艺影响的诸多因素,寻找最佳工艺控制方案。合成控制的四氟丙酸钠方案与其它同类方案相比有着简单易行,控制技术优越的特点,具有广阔的应用前景。更多还原

【Abstract】 In view of the present pesticides in China,which are of high poison,and high rudiment,we have developed a new pesticide sodium tetrafluopropanate of low poison but high efficiency.According the choice of course of compound technique,in pursuit of the best blue print of technique control.The compound control of sodium tetrafluopropanate,compared with other similar programmers have a simple programmer,control technologies superior features,broad prospects for application.更多还原
