本文按农药类型及化学结构对国内外农药用原料及中间体进行了简要的介绍,并预测其发展趋势。文中所介绍农药品种的生物活性、毒性、对作物及环境的安全性等方面均符合高效、低毒、安全的标准,并各具特点。含氟、含杂环、含氟杂环及立体选择性中间体的研究与合成,对现有中间体工艺的改进(使之收率更高、三废更少、成本更低)或“绿色工艺”的研究是农药原料或中间体的发展趋势。
This article briefly introduces domestic and foreign pesticide raw materials and intermediates according to pesticide type and chemical structure, and predicts its development trend. The biological activity, toxicity, safety of crops and the environment, etc. of pesticide species introduced in the article are all in accordance with the standards of high efficiency, low toxicity, and safety, and have their own characteristics. Research and synthesis of fluorine-containing, heterocyclic-containing, heterocyclic fluorine-containing heterocycles, and stereoselective intermediates, improvements to existing intermediate processes (increased yield, less waste, lower cost) or “green processes ”The study is the development trend of pesticide raw materials or intermediates.
