摘要
本文对新型除草剂安磺灵的合成工艺进行了研究。改进了中间体3,5-二硝基-4-二正丙胺基苯磺酰氯和最终产品安磺灵的合成方法,使之更适合于工业生产的要求。安磺灵的总收率在55%以上。
In this paper, the process of synthesizing new model weedicide oryzalin was studied.The syntheses of 3,5-dinitro-4-di-n-propylamidobenzenesulfong chloride and oryzalin was improved, makes more is fit for the requirement in the industrial production.The total yield of oryzalin was over 55%.
