摘要
2,3-二氯吡啶是一种非常重要的化工中间体,是有效合成氯虫苯甲酰胺的核心物质。确定了烟酰胺合成2,3-二氯吡啶工艺路线,即以烟酰胺为原料,经过Hofmann重排、氯化、重氮化和氯代反应等,并进行了原料成本核算。该法经济、合理,易于实现工业化。
2,3-Dichloropyridine is a very important chemical intermediate for synthesizing chlorantraniliprole.To determine the synthetic methods of 2,3-dichlorpyridine,that is ,it is prepared with nicotinamide as raw material and through hofmann degradation,chlorination,diazotization and sandmeyer reaction starting with nicotinamide .To account the raw material cost of the synthetic method.The method is economic,reasonable and easy to industrialize.
