吡唑硫磷

吡唑硫磷用途

【用途一】
本品对离体抗乙酰胆碱酶活性差，但对斜纹夜蛾有很好的杀虫活性，其幼虫的乙酰胆碱酯酶因本品中毒而导致抑制。本品对昆虫脂族酯酶（与神经系统的乙酰胆碱酯酶相比）显示较高的抑制活性。具触杀和胃毒作用，对根系无内吸活性。对鳞翅目、鞘翅目、蚜虫、双翅目和蜚蠊等多种害虫均有效，对叶螨科螨、根螨属蟥、蜱和线虫也有效。田间试验表明，防治对象还有棉铃虫、红铃虫、海滨夜蛾、棉飞虱、烟蓟马、马铃薯甲虫、马铃薯块茎蛾、茶叶细蛾、茶黄蓟马、苜蓿叶象甲、烟草天蛾。用药量为0.5～1.5kg (有效成分）/hm²。对苹果、柑橘、日本梨等果树有轻微药害，随品种有异。

详细合成路线

吡唑硫磷上下游产品

吡唑硫磷上游产品

吡唑硫磷下游产品

吡唑硫磷制备

1.以双乙烯酮、对氯苯胺为原料，制得3-氯丙酮醛对氯苯腙。然后在氢氧化钠存在下，于甲醇中环合，生成l－（4-氯苯基）-4－羟基吡唑，最后在三乙胺存在下，在乙睛中，与O-乙基－S－丙基磷酰氯在50℃反应3h,即制得本品，收率78%以上.或用转位方法制得。

2.吡唑硫磷的合成1-（4-氯苯基）-4-羟基吡唑在三乙胺存在下，于乙腈溶液中，O-乙基-S-丙基硫代磷酰氯作用，反应温度50℃，反应时间３h，制得吡唑硫磷。
