摘要
本文介绍了农药中间体5-乙基吡啶-2,3-二甲酸二乙酯合成路线,通过试验分析,将生产过程中产生的废水进行回收,选择出适合工业化的清洁合成工艺,无三废,实现清洁合成。2步反应得到产品,总收率为70%(以乙氧基乙酸乙酯计),含量为85%。
The were reviewed. 3-dicarboxylic methods for synthesis of 5-ethyl-pyridine-2,3-dicarboxylic acid diethyl ester The clean synthesis route was found by experiment that the 5-ethyl-pyridine-2, acid diethyl ester was synthesized by two-step reaction, the yield rate was 70% （base on ethyl ethoxy acetate）, the purity of the final product was 85%.
