摘　　要：目前国内生产精喹禾灵关键中间体2-羟基-6-氯喹噁啉主要用硫化钠还原,其产生的污水多且难处理;而文章采用双氧水作为还原剂,大大缓解了生产过程中污水的处理难题,为以后精喹绿色生产提供较好路线。6-Chloro-2-hydroxyl-quinoxaline is a key internediate for the syntheses of qulzalofog-P-ethyl, which is mainly restored of sodium sulfide and the sewage is much and difficult to handle. So H2O2 is adopted as reducing agent in the paper.Which solve the problem of sewage, and to provide the better Synthesis line of qulzalofog-P-ethyl in the future.
