哌草丹

哌草丹用途

内吸传导型选择性稻田除草剂。对防除2叶期以前的稗草效果突出。药剂由根系、茎、叶吸收后传导至整个植株，打破内源生长素的平衡，进而使细胞内蛋白质合成受阻，破坏生长点细胞的分裂，达到抑制和延迟杂草茎叶的形成，生长发育停止，茎叶由浓绿变黄、变褐至枯死。如水稻旱种田在出苗后，稗草1.5～2.5叶期，每百平方米用哌草丹50%乳油30mL加20%敌稗乳油75～112.6mL，对水4.5～6kg，茎叶喷雾。旱育秧及湿润秧苗在播前或播后，每百平方米用50%乳油22.5～30mL，对水3.75～4.5kg床面喷雾，水育秧苗可在播后1～4d用毒土法施药。插秧田在插秧后3～7d，用50%乳油22.5～39mL对水喷雾。施药后保持3～5cm水层5～7d。当稻田杂草种类较多时，宜与其他除草剂混用。

哌草丹制备

以甲苯或哌啶为溶剂，加入α，α-二甲基苄硫醇，然后在室温下滴加40%氢氧化钠溶液，回流反应，分去水分。升温至60～70℃，滴加哌啶甲酰氯，滤去析出的氯化钠，升温反应数小时，经水洗、干燥、脱溶得哌草丹。
α，α-二甲基苄硫醇的合成方法如下：以1，4-二氧六环为溶剂，在催化剂存在下，α-甲基苯乙烯与硫化氢反应制得，收率86.3%。
也可采用二甲基亚砜为溶剂，将相应的硝基化合物用Na2S2处理，所得物在0℃与铝汞齐作用制得，收率达92%。
