苯达松制备

1.由异丙胺盐酸盐和二氯硫酰反应得到异丙胺磺酰氯，再与邻氨基苯甲酸甲酯缩合，最后闭环而得苯达松。1.异丙胺磺酰氯的合成异丙胺加入冷却的盐酸中，制得异丙胺盐酸盐水溶液，蒸去水分，再在150℃进一步脱净水分。冷却后的异丙胺盐酸盐、乙腈和二氯硫酰加入异丙胺磺酰氯合成釜中，加热回流反应，蒸出乙腈及剩余的二氯硫酰，得异丙胺磺酰氯粗品。操作的工艺条件为：配料比（摩尔比）：异丙胺盐酸盐：二氯硫酰：乙腈=1：3：6反应温度和时间：沸腾回流，反应温度高于60℃的时间不少于16h，反应最终温度65-70℃异丙胺磺酰氯含量70%，收率90%以上。2.苯达松合成在甲苯溶剂中，以氨为缚酸剂，异丙胺磺酰氯和邻氨基苯甲酸甲酯缩合生成N-异丙胺磺酰基邻氨基苯甲酸酯，然后加入甲醇纳使之闭环，生成苯达松钠盐、酸化、过滤、干燥，得苯达松成品，缩合投料比（摩尔比）：异丙胺磺酰氯：邻氨基苯甲酸甲酯：甲苯=1：0.9：6；缩合反应液pH=5-6.5；缩合温度：50-55℃；反应1h。闭环投料比（摩尔比）；异丙胺磺酰氯：甲醇钠=1：2；闭环温度60-65℃，反应30min。苯达松平均总收率54%以上。原药平均有效成分82%以上。原料消耗定额：异丙胺（98%）464kg/t、乙腈（98%）275kg/t、二氯硫酸2475kg/t、邻氨基苯甲酸甲酯（工业品）957kg/t、甲苯443kg/t、甲醇钠（30%）2537kg/t、盐酸（30%）1488kg/t、合成氨（99%）80kg/t。

2.首先将异丙胺加入冷却的盐酸中，制得异丙胺盐酸盐水溶液，蒸去水分，再在150℃进一步脱净水分，冷却后得到的异丙胺盐酸盐与乙腈、二氯硫酰加入异丙胺磺酰氯中，加热回流反应，处理得到异丙胺磺酰氯。另将苯酐与氨水、氢氧化钠作用，制得邻甲酰胺苯甲酸钠，然后由邻甲酰胺苯甲酸钠与次氯酸钠、氢氧化钠、甲醇反应制得邻氨基苯甲酸甲酯。最后以甲苯为溶剂，氨为缚酸剂，将上面制得的异丙氨基磺酰氯加入到邻氨基苯甲酸甲酯中，加热反应生成犖异丙胺磺酰基邻氨基苯甲酸甲酯，然后在甲醇钠溶液中进行环合反应，再经酸化制得灭草松。
