毒理性
  • 解毒与急救
这些除草剂的摄入可能会因刺激性特性而导致呕吐和腹泻。活性炭可能有效于限制刺激性影响并减少对大多数或所有这些除草剂的吸收。氢氧化铝抗酸剂可能有助于中和大多数酸性物质的刺激性作用。如果存在肠鸣音且自发腹泻尚未开始,应给予山梨醇以诱导泻药。脱水和电解质紊乱可能严重到需要静脉输液。这些除草剂的中毒没有特定的解毒剂。如果摄入了大量除草剂,且患者在摄入后一小时内被看到,应考虑进行胃肠道净化。/其他除草剂/
Ingestions of these herbicides are likely to be followed by vomiting and diarrhea due to the irritant properties. ... Activated charcoal is probably effective in limiting irritant effects and reducing absorption of most or all of these herbicides. Aluminum hydroxide antacids may be useful in neutralizing the irritant actions of most acidic agents. Sorbitol should be given to induce catharsis if bowel sounds are present and if spontaneous diarrhea has not already commenced. Dehydration and electrolyte disturbances may be severe enough to require intravenous fluids. There are no specific antidotes for poisoning by these herbicides. ... If large amounts of herbicide have been ingested and the patient is seen within an hour of the ingestion, gastrointestinal decontamination should be considered. /Other Herbicides/

毒理性
  • 解毒与急救
如果严重的脱水和电解质流失是由呕吐和腹泻引起的,监测血液电解质和液体平衡,并给予葡萄糖、生理盐水、林格氏溶液或林格乳酸盐的静脉输液,以恢复细胞外液体积和电解质。一旦能够保留液体,随即给予口服营养。对于这些除草剂过度暴露的成功管理,通常支持性措施就足够了。尽管有良好的支持性护理,如果患者的状况仍然恶化,应怀疑有其他替代或额外的毒素作用。/其他除草剂/
If serious dehydration and electrolyte depletion have occurred as a result of vomiting and diarrhea, monitor blood electrolytes and fluid balence and administer intravenous infusions of glucose, normal saline, Ringers solution, or Ringers lactate to restore extracellular fluid volume and electrolytes. Follow this with oral nutrients as soon as fluids can be retained. Supportive measures are ordinarily sufficient for successful management of excessive exposure to these herbicides. If the patients condition deteriorates in spite of good supportive care, the operation of an alternative or additional toxicant should be suspected. /Other Herbicides/

Body weight gain was reduced 17% and 14% for high dose males and females, respectively. Total cholesterol, bilirubin levels, and liver weights were elevated at 900 to 2700 ppm. Swollen liver cells were increased in dose-related fashion in 900 ppm to 2700 ppm males. High dose females were similarly affected, but at lower incidence.

制备方法与用途

烯禾啶概述

烯禾啶,商品名为拿捕净,是一种具有内吸传导性的茎叶处理除草剂。它广泛应用于大豆、花生、棉花、油菜等阔叶作物田防除禾本科杂草,具有安全、广谱、高效、低毒的优点。

应用

目前,烯禾啶常与其他成分复配使用:可用于制备含氯氨吡啶酸与烯禾啶的混合除草剂;也可用于制备含有烯禾啶和灭草松的除草组合物。

毒性

大鼠急性经口LD50为3200~3500毫克/公斤,急性经皮LD50大于5000毫克/公斤,急性吸入LC50大于6.28毫克/升(4小时)。对兔皮肤和眼睛无刺激作用。大鼠3年饲喂试验未见致畸、致癌、致突变作用。鲤鱼LC50为148毫克/升(96小时),鹌鹑急性经口LD50大于5000毫克/公斤;对蜜蜂无明显危害。

作用机理与特点

烯禾啶是一种ACCase抑制剂,选择性强的内吸传导型茎叶处理剂。它能被禾本科杂草茎叶迅速吸收并传导到顶端和节间分生组织,破坏细胞分裂,生长点和节间分生组织开始坏死。受药植株3天后停止生长,5天后心叶容易拔出,7天后新叶褪色或出现花青素颜色,基部变褐色枯死,10-15天整株枯死。

化学性质

烯禾啶为淡黄色液体,无臭味。沸点大于90℃/4×10^-3帕,相对密度1.05(20℃),能溶于甲醇、辛醇、醋酸乙酯、己烷、苯、二甲苯等多种有机溶剂,在水中溶解度为25毫克/升(pH=4)、4.7克/升(pH=7)。土壤中半衰期小于1天(15℃)。

用途

烯禾啶是一种选择性很强的内吸传导型茎叶处理剂,可用于大豆、棉花、油菜、花生、马铃薯、甜菜、向日葵、亚麻等作物及果园防除稗草、野燕麦、狗尾草、看麦娘、马唐、牛筋草等,对阔叶杂草无效。防治大豆、棉花地杂草时,分别用20%乳油10~20毫升/平方米或12.5%机油乳油10~15毫升/平方米对水喷雾。

生产方法

烯禾啶的生产过程包括以下几个步骤:

  • ETO制备:以丁烯-2-醛为原料,在步胺催化下与乙硫醇加成生成3-乙硫基丁醛;乙酰乙酸甲酯经水氏妥生成乙酰乙酸钠;将3-乙硫基丁醛与乙酰乙酸钠作用,以N-甲基己胺为催化剂在20~40℃反应生成6-乙硫基-3-庚烯-2-酮(简称ETO)。
  • CDNA制备:ETO在甲醇钠存在下与丙二酸二甲酯发生迈克尔加成,然后经环合、水解、脱羧生成1,3-环己二酮,再经乙硫基化反应最终得到1,3-环己二酮(简称CDNA)。
  • 稀禾定合成:以丁酰氯为酰化剂进行酰化反应,酰化产物在4-N,N-二甲基吡啶催化作用下发生转位重排。再与乙氧基胺在40~60℃温和条件下进行缩合形成肟,制得稀禾定。
