吡啶主要用于合成农药除草剂百草枯、敌草快和杀虫剂毒死蜱等。百草枯和敌草快在工业上只采用吡啶为原料来合成,毒死蜱有吡啶路线和非吡啶路线两种工业化生产技术,农药是吡啶主要的下游消费领域。吡啶是合成第四代杂环农药的“芯片”之一。吡啶衍生物的定向氯化、氟化技术还被定为“十二五”鼓励项目。同期印发的《农药工业“十二五”发展规划》要求提高科技创新能力,要求重点开发吡啶及其衍生物定向氯化、氟化技术。
Pyridine is mainly used for the synthesis of pesticide herbicides paraquat, diuron quick and insecticides chlorpyrifos. Paraquat and Diquat fast in the industry using only pyridine as raw materials to synthesize, chlorpyrifos with pyridine route and non-pyridine route two industrial production technology, the main downstream consumption of pyridine pesticides. Pyridine is one of the “chip” of the fourth generation of heterocyclic pesticides. Directed chlorination of pyridine derivatives, fluorination technology has also been designated as “second five ” encouragement project. The “Pesticide Industry” Twelfth Five-year Development Plan issued in the same period calls for improving the capability of scientific and technological innovation, and requires the key development of directional chlorination and fluorination of pyridine and its derivatives.
