2.6-二氯喹噁啉是一种淡黄色结晶体,主要用作一系列除草剂和一些药物合成的中间体。传统工业生产主要采取2-硝基-4-氯苯胺与双烯酮缩合、环化、氯化等步骤制得。据资料介绍,日本专利提出采取2-羟基喹噁啉路线,经两步氯化合成题名产物,收率比传统方法提高15%,纯度提高近5%,而且三废大大减少,成本也大大降低。国内现有2,6-二氯喹噁啉均采用传统工艺路线,生产 2.6-Dichloroquinoxaline is a light yellow crystalline substance that is mainly used as a series of herbicides and intermediates in the synthesis of some drugs. Traditional industrial production mainly takes 2-nitro-4-chloroaniline and diketene condensation, cyclization, chlorination and other steps in the system. According to the information, the Japanese patent proposed to take 2-hydroxyquinoline line, after two steps of chlorination synthesis of the title product, the yield was 15% higher than the traditional method, the purity increased by nearly 5%, and significantly reduced waste, the cost is greatly reduced. 2,6-Dichloroquinoline existing domestic use of traditional routes, production
