氟虫腈是广谱、超高效农用杀虫剂,由于其独特的杀虫效果,目前已得到国内外市场的普遍认可,开发该品种符合我国农药产品发展方向和产业政策。河北省石家庄市三农化工有限公司近期成功开发出以吡唑腈与三氟甲基亚磺酸钠氯合成氟虫腈的清洁工艺,并开发出新催化剂,同时强化了催化剂及溶剂的回收。 Fipronil is a broad-spectrum, ultra-efficient agricultural pesticide. Due to its unique insecticidal effect, fipronil has been widely recognized by domestic and foreign markets. It is in line with the development direction and industrial policy of pesticide products in China. Recently, Shijiazhuang Sannong Chemical Co., Ltd. of Hebei Province has successfully developed a cleaning process for the synthesis of fipronil from pyrazolonitrile and sodium trifluoromethylsulfinate, and developed new catalysts. Meanwhile, it has also enhanced the recovery of catalysts and solvents.
