氯代吡啶类化合物主要包括氯代元素氟、氯、溴、碘的化合物,其中氯代吡啶作为农药工业的重要原料,主要应用于农药中间体。但是世界吡啶氯代化合物生产的一些关键技术主要集中在美国、欧洲、日本等地区和国家,我国生产技术落后,产品大量依靠进口。随着吡啶化合物市场不断发展,研究和生产吡啶氯代化合物已成为非常迫切的需求。通常吡啶的合成 Chloropyridines include chlorinated compounds of fluorine, chlorine, bromine and iodine. Among them, chloropyridine is an important raw material in pesticide industry and mainly used in pesticide intermediates. However, some key technologies of the production of pyridine chlorinated compounds in the world are mainly concentrated in the United States, Europe, Japan and other regions and countries. Our country’s production technology is backward and products are heavily imported. As the pyridine compound market continues to evolve, research and production of pyridyl chlorides have become very urgent needs. General pyridine synthesis
