[0002] Difluorobenzonitrile is a specific insect growth regulator and an essential intermediate for benzamide pesticides such as diflubenzuron and chlorfenapyr. It can be used as a raw material to react with other compounds under the catalysis of polyethylene glycol. In addition, difluorobenzonitrile can be used as an intermediate for the synthesis of a variety of medicines, dyes, and liquid crystal materials. It is also an important intermediate for the selective herbicide cyhalofop-butyl. The finished difluorobenzonitrile, especially 2,6-difluorobenzonitrile, is a white solid powder. During its production process, the staff will use a rotary vibrating screen to screen the finished powder to select powder with qualified fineness.
