Description
技术领域
本发明涉及一种经济上合理,对设备腐蚀性不大,选择性好且副产物含量低的一种制备氟虫腈的方法。
背景技术
氟虫腈(目标产物)是一种苯基吡唑类杀虫剂、杀虫谱广,对害虫以胃毒作用为主,兼有触杀和一定的内吸作用,其作用机制在于阻碍昆虫γ-氨基丁酸控制的氯化物代谢,因此对蚜虫、叶蝉、飞虱、鳞翅目幼虫、蝇类和鞘翅目等重要害虫有很高的杀虫活性,对作物无药害。该药剂可施于土壤,也可叶面喷雾。施于土壤能有效防治玉米根叶甲、金针虫和地老虎。叶面喷洒时,对小菜蛾、菜粉蝶、稻蓟马等均有高水平防效,且持效期长。近年来,氟虫腈也广泛用于卫生杀虫剂。主要用于防杀蟑螂、蚂蚁等有害生物。
氟虫腈的化学名是 5-氨基-3-氰基-1-(2,6-二氯-4-三氟甲基苯基)-4-三氟甲基亚磺酰基吡唑,商品名为锐劲特,是法国罗纳-普朗克公司于1987至1989年开发研制,1992年在我国登记的高效杀虫剂。
合成该化合物的方法主要有以下几类:
第一类合成方法见WO295117,其缺点在于使用间氯过氧苯甲酸为氧化剂,非常昂贵,而且纯化方法需要层析。
第二类方法在欧洲专利1222173中有描述,使用三氟乙酸和双氧水进行氧化,对设备腐蚀性太大。
第三类合成方法在WO2007122440中有所描述,使用三氯乙酸和过氧化氢进行反应,腐蚀性相对比三氟乙酸要好,反应选择性较差,有5-10%的砜副产物(FD)。
第四类合成方法在CN201180034433中有详细描述,使用二氯乙酸和过氧化氢进行反应,跟第三类一样,反应选择性较差,有5-10%的砜副产物(FD);
综上所述,现有的几种方法都有不可避免的缺陷,要么经济上不合理,要么对设备腐蚀性大,要么选择性差,副产物含量高。
发明内容
设计目的:避免背景技术存在的不足之处,提供一种简便易行、经济上合理的、对设备没有腐蚀性、选择性好且副产物少的一种制备氟虫腈的方法。
设计方案:为了实现上述设计目的。本发明所述方法以结构式为:
化为物(简称MP)为原料在氯代烃类溶剂条件下,用过硫酸化合物氧化制备得到结构式为目标产物氟虫腈,即:
过硫酸化合物为过硫酸、过硫酸钠、过硫酸钾、过硫酸钙和过硫酸镁中的一种或任意几种的组合。
上述过氧化物都是常见的氧化剂,市面上可以直接购买,不像间氯过氧苯甲酸那样贵,而过硫酸化合物对设备要求低,只要求普通搪玻璃反应釜即可,不会像三氟乙酸那样腐蚀搪玻璃,并且使用过硫酸化合物,砜副产物(FD)在选定的条件下可以控制在3%以下。
按照本发明,氧化反应是在搪玻璃反应釜内反应,反应压力常压,反应温度-10℃-80℃,优选0℃-5℃,反应温度低于-10℃,反应不进行,反应温度高于80℃,砜副产物(FD)会大于5%,优化的条件是在0℃-5℃。
MP与氧化剂的当量比为为:1:1-1.2;氧化剂当量比小于1:1,MP剩余会大于2%,氧化剂当量比大于1:1.2,即使是在选定的温度条件下,砜副产物(FD)会大于5%;
此反应所用溶剂为二氯甲烷、二氯乙烷、氯仿等氯代烃类溶剂。
砜副产物(FD)的结构式为:
反应完成后经过亚硫酸钠淬灭、水析、离心等常规方法处理即可得到氟虫腈。
本发明与背景技术相比,方法具有经济上合理、对设备没有腐蚀性以及反应选择
性好的优点,并适于进行工业化生产。

实施例2:向反应釜中加入MP421.1kg(1.0当量),溶剂二氯甲烷1000kg,开启搅拌,控温0-5℃通过加料器向反应釜中加入过硫酸186.2kg(0.95当量),经取样管取样检测MP2%,FD1.3%,加入亚硫酸钠5kg,反应釜内加水100kg *2水洗,有机层再用100kg 10%碳酸氢钠水洗,再经减压脱溶,降温结晶,所得氟虫腈349.6kg(含量94.5%,收率80%)。
实施例3:其他同实施例1,过硫酸245kg(1.25当量),经取样管取样检测MP0.4%,FD3.2%所得氟虫腈含量94.0%,收率97.9%。
