补充资料:抑芽丹
分子式:C4H4N2O2
分子量:112.09
CAS号:123-33-1

性质:白色结晶。260℃分解,熔点>300℃。25℃时在水中溶解度约为0.6%,在乙醇中溶解度为0.1%,在二甲基甲酰胺中为2.4%。其钠、钾和铵盐及有机磷盐类易溶于水。

制备方法:由顺丁烯二酸酐与水合肼反应而得。在反应锅中投入水及40%水合肼,搅拌冷却下滴加30%盐酸,温度控制在20℃以下,至pH值为6.2-6.4,投入顺丁烯二酸酐,缓缓升温至106-110℃,回流2h,降温至5℃,甩滤,滤饼用冰水洗至pH4.8-5.1,干燥,得顺丁烯二酰肼,收率97%。

用途:顺丁烯二酰肼为选择性除草剂和暂时性植物生长抑制剂。药剂可通过叶面角质层进入植株,降低光合作用、渗透压和蒸发作用,能强烈地抑制芽的生长。用于防止土豆、洋葱、大蒜和萝卜贮藏期发芽,并有抑制作物生和延长开花的作用,也可用于非耕地除草。该品的互变异构为3,6-二羟基哒嗪(3,6-Dihydroxypyridazine)。是磺胺类药物磺胺甲氧嗪的中间体。
