磺草灵合成路线

磺草灵上下游产品

磺草灵上游产品

磺草灵下游产品

磺草灵制备

（1）4-氨基苯磺酰胺与氯代甲酸甲酯反应，该反应在水或有机溶剂中进行，缚碱剂存在下，在水介质中的最适宜反应温度为10～20℃，在有机介质中于回流温度下，前者用氢氧化钠，后者在丙酮中用碳酸钾，即制得磺草灵。

（2）14kg(10.0mol)4-乙酰氨基苯磺酰胺、1.75kg(12.7mol)无水碳酸钾和16L丙酮的混合物在搅拌下，缓慢加入1.14kg(12.1mol)氯甲酸甲酯。加毕，混合物搅拌下回流18小时，然后冷却制室温，过滤，固体部分悬浮水中，用盐酸酸化，得中间物粗品，然后溶解在1mol碳酸氢钠水溶液中，过滤后的绿叶再用盐酸酸化至酸性，精制的中间物乙酰氨基苯磺酰氨基甲酸甲酯，收率45.9%，产量1.25kg，白色固体，熔点235～237℃。将572g(2.1mol)中间物溶解在2mol氢氧化钠中，室温下放置2天后，用浓盐酸酸化，生成的沉淀物用2mol/L盐酸提取，起先得到的提取盐酸加到滤液中，然后用50%情；氢氧化钠水溶液调PH值至4，得289g(1.25mol)磺草灵，收率60%，熔点145～146℃。用盐酸提取子不溶物（218g,0.8mol）加水分解的残留物为中间物，可循环使用，水解收率达96%。

3.由氯甲酸甲酯与甲醇回流反应，脱去１分子氯化氢，生成碳酸二甲酯；然后将碳酸二甲酯在甲醇钠存在下与对氨基苯磺酰胺作用，生成磺草灵。
