溴虫腈是一种新型取代芳基吡咯类杀虫剂,因其低毒特性,被农业部推荐为无公害农药。溴虫腈在中国的专利将于今年到期,目前国内合成研究主要采取的是肌氨酸路线,不仅原材料供应紧张,而且环境污染严重,所以立足于国内原材料,开发出低成本、环境污染少的新合成工艺是非常必要的。 Chlorfenapyr is a new substituted aryl pyrrole insecticide, because of its low toxicity, recommended by the Ministry of Agriculture as a pollution-free pesticide. The patent of chlorfenapyr in China will expire this year. At present, the synthetic route of sarcosine mainly adopts the sarcosine route. Not only the supply of raw materials is very tight, but also the environment is polluted. Therefore, based on the domestic raw materials, we have developed a low cost and less environmental pollution The new synthetic process is very necessary.
