摘    要:本文研究了用碳酸钠和碳酸钾混合试剂合成除草醚的新方法。此法改变原碳酸钾法固体加料成盐,采用把混合试剂配成水溶液回流成盐的方法,产品质量好,收率高,成本大幅度下降。


SYNTHESIS OF 2, 4-DICHLORO-4'-NITRO-DIPHENYLE—THER FROM Na_2CO_3, K_2CO_3 MEDIUM
Abstract:A new synthetic method of 2, 4-diclhoro-4'-nitro-diphenyle—ther has been ProPosed. This method is superior than the traditional method in the following respects. First, cheap Na_2CO_3 is used to replace part of the expensive K_2CO_3. Second, the salt is produced by refluxing the reactant in aqueous solution instead of adding solid K_2CO_3 to the reaction mixture. The quality of the product is improved and the cost is much lowered by this new method.
