补充资料:拉索
分子式:C14H20ClNO2
分子量:269.770
CAS号:15972-60-8

性质:纯品为结晶。熔点40-41℃。23℃时水中溶解度为240ppm。可溶于丙酮、苯、乙醇、乙酸乙酯。挥发性极小。抗紫外线分解。在强酸或碱性条件下分解。在土壤中半衰期约15d。

制备方法:由2,6-二乙基苯胺与甲醛水溶液反应,生成2,6-二乙基甲叉苯胺,然后与氯乙酰氯反应生成加成物。后者与甲醇反应,用氨作缚酸剂,脱去一分子氯化氢,即得甲草胺,为棕色或紫色稠状液体或半固体。原料消耗定额:2,6-二乙基苯胺780kg/t、多聚甲醛200kg/t、氯乙酸700kg/t、甲醇340kg/t、三氯化磷540kg/t。

用途:甲草胺被杂草的幼苗根部吸收,干扰核酸和蛋白质合成,阻止细胞增大,从而抑制根的伸长,然后影响全株生长,使杂草死亡。是一种选择性芽前除草剂,主要用于玉米、大豆、花生、甘蔗,也可用于非砂性土壤的棉花、油菜、马铃薯和洋葱、辣椒、甘蓝等作物,防治一年生杂草和某些阔叶杂草。在出芽前作土面处理。根据土壤类型用量为2.5~4kg(有效成分)/hm2,有效期为4-8星期。
