油水分配系数/LogP:

LogP值指的是某物质在正辛醇/水两相体系中的分配系数的对数值,反映了物质在油水两相中的分配情况。其中、LogP值越大,说明该物质越亲油;反之,LogP值越小,则说明该物质越亲水。

生产制备方法及用途展开↓

制备方法


在一定压力和氢氧化钠存在下,西玛津和甲硫醇钠作用,于70~75℃回流反应3h,冷却结晶,水洗干燥得西草净,溶剂经回收处理。

合成制备方法


在氢氧化钠存在下,三聚氯氰与一乙胺、甲硫醇钠反应,即制得西草净。原料消耗定额:三聚氯氰1200kg/t、一乙胺660kg/t、甲硫醇钠550kg/t。在一定压力和氢氧化钠存在下,西玛津和甲硫醇钠作用,于7075回流反应3h,冷却结晶,水洗干燥得西草净,溶剂经回收处理。

用途简介


属选择性内吸传导型除草剂,主要用于水稻,也可用于玉米、大豆、小麦、花生、棉花等。

用途


选择性、内吸传导型均三氮苯类除草剂。能通过杂草根、叶吸收,并传导至植株全身,抑制杂草光合作用,使叶片缺绿变黄而死亡。主要用于水稻,也可用于玉米、大豆、小麦、花生和棉花等作物,防除眼子菜、牛毛草、稗草、野慈姑、苦草、瓜皮草、水鳖、三棱草、苋菜、铁苋菜、藜、蓼等杂草。如防除水稻眼子菜,则在水稻移栽后1520d,当眼子菜盛发,叶片由红转绿时,用25%可湿性粉剂1522.5g/100m2 ,混细潮土3kg撒施,或对水7.5kg喷雾,施药时田间罐45cm水层,施后保持45d,然后让田自然落干。选择性内吸传导型除草剂,主要用于稻田防稗草、牛毛草、眼子菜、泽泻、野慈姑、母草、小慈草等,与杀草丹、丁草胺混用,可扩大杀草谱,也可用于玉米、大豆、小麦、花生、棉
