Description

一种环氧啉的制备方法
技术领域
本发明属于杀虫剂制备技术领域,具体涉及1-(2,3-环氧丙基)-N-硝基亚咪唑烷-2-基胺即环氧啉的制备方法。
背景技术
环氧啉是基于计算机辅助药物分子设计(CADD)方法,即利用COMFA模拟结果,合成的4种新烟碱类化合物中杀虫效果最好的一种,其杀虫活性与全球市场销量最大的杀虫剂——吡虫啉的杀虫活性相当。但吡虫啉的广泛使用已使害虫产生了一定的抗药性,并且合成吡虫啉所用原料吡啶不但成本高,而且在生产过程中产生大量的污染物。而环氧啉不仅能有效地克服以上缺点,并且与吡虫啉一样具有较好的杀虫效果,且毒性更低,作为一种新化合物,具有选择性高、安全性好等特点,生产成本也仅为吡虫啉的三分之一,具有更加广阔的应用前景。2009年,中国专利CN 101503406A公开了1-(2,3-环氧丙基)-N-硝基亚咪唑烷-2-基胺的两种合成路线,路径1采用两步合成法,首先边搅拌边向乙二胺中滴加环氧氯丙烷,在温度为45℃左右,反应2~3h后减压蒸馏除去溶剂得到中间体环氧丙基乙二胺,然后将中间体和硝基胍溶于水中,边搅拌边滴加稀盐酸,于85℃左右反应2~3h后冷却,用二氯甲烷萃取,减压蒸馏除去溶剂,用丁酮重结晶,两步反应,反应温度较高,且后处理过程需使用大量的二氯甲烷等溶剂进行萃取,因此产品工业化价值不大。路线2先将N-硝基亚咪唑烷、碳酸钾及有机溶剂加入到反应瓶中,加热到80℃待反应物溶解后向其中滴加环氧氯丙烷,反应加热4h后结束,冷却到室温后,过滤,滤液蒸干,所得残留物加水,再用二氯甲烷萃取,减压蒸馏除去溶剂,再用丁酮重结晶,其后处理工艺较为繁琐,并且收率较低,限制了其工业化的生产应用。
发明内容
本发明针对现有技术存在的上述技术问题,提供一种环氧啉的制备方法。本发明采用N-硝基亚氨基咪唑烷和环氧氯丙烷为原料制备环氧啉:1-(1,2-环氧丙基)-N-硝基亚咪唑烷-2-基胺。
本发明所提供一种环氧啉的制备方法的具体步骤如下:
(1)在氮气保护下,将N-硝基亚氨基咪唑烷和有机溶剂加入到反应器中,然后分批加入氢化钠,加热至温度50~60℃,待N-硝基亚氨基亚咪唑烷溶解后,向反应器中慢慢滴加环氧氯丙烷,滴加完毕,继续加热反应1~1.5h至反应结束,用TLC或HPLC监测反应进程。
所述环氧氯丙烷、N-硝基亚氨基咪唑烷及氢化钠的摩尔比为:环氧氯丙烷∶N-硝基亚氨基咪唑烷∶氢化钠=1:1.1-1.5:1.1-1.5;所述有机溶剂为N,N'-二甲基甲酰胺或N,N'-二甲基甲酰胺与甲苯的混合溶剂;所述氢化钠的纯度为60wt%。
(2)待步骤(1)反应产物冷却后,向其中加入所述反应产物0.5倍体积的氯仿,进一步从有机溶剂中析出溶解的氯化钠副产物,用硅藻土过滤,除去滤液中氯化钠盐分,并通过水洗硅藻土以分离出氯化钠,再蒸发结晶析出。
(3)将经过步骤(2)处理后的滤液减压蒸馏除去大部分有机溶剂,得到淡黄色稠状固体,然后用热的氯仿萃取,再除去溶剂后得淡黄色固体产品,干燥后得环氧啉:1-(2,3-环氧丙基)-N-硝基亚咪唑烷-2-基胺的粗品,减压蒸馏温度为40℃,压力为0.3Kpa。
(4)最后用热的乙醇或丙酮对步骤(3)得到的环氧啉:1-(2,3-环氧丙基)-N-硝基亚咪唑烷-2-基胺粗品进行重结晶,最后制得所述环氧啉:1-(2,3-环氧丙基)-N-硝基亚咪唑烷-2-基胺的纯品,产率约为83%。
其中:氢化钠分批加入,因为加入氢化钠会产生大量的氢气;抽滤时,使用硅藻土或白土可以较为彻底脱盐并分离出盐分副产品。
上述过程的反应式如下:
本发明具有以下技术特点:
1、采用氢化钠可以有效的将N-硝基亚氨基咪唑烷中共振式中酸性较弱的氢完全解离并转为钠盐,且不会产生其他有机副产物。
2、使用极性和溶解性更强的N,N'-二甲基甲酰胺为反应溶剂,可以大大减少溶剂的使用量,而且减压蒸馏出的N,N'-二甲基甲酰胺可以循环套用,更加经济环保。
3、反应温度为50~60℃,热条件更加温和,能耗更少。
4、产物分离过程中可有效分离出副产品氯化钠,以减少固体废弃物的产生。
5、氯仿在反应后续处理过程中也可以循环利用,减少成本。
6、相比现有技术,本发明方法反应时间更短,收率更高,且后处理工艺也相对简单。
总之,本发明方法是制备环氧啉的一种比较绿色环保的工艺方法,具有更高的实用价值,更适合于大规模工业化生产。
