Izakhiwo zamakhemikhali:

I-2,6-difluorobenzamide iyikristalu emhlophe ewuphawuda, mp143 ~ 145℃, ayincibiliki emanzini

Ukusetshenziswa:

Lo mkhiqizo usetshenziswa njengendlela yokuhlanganisa izibulala-zinambuzane ze-fluorobenzoyl urea. Ungasetshenziswa ukukhiqiza izibulala-zinambuzane ezahlukahlukene kanye ne-acaricides njenge-hexaflumuron, i-chlorfenapyr, kanye ne-diflubenzuron. Uphinde usetshenziswe kwezokwelapha kanye nezinto zekristalu eliwuketshezi. Umkhiqizo usebhokisini lekhadibhodi elifakwe isikhwama sepulasitiki, elinesisindo esingama-25kg ngebhereli.

Indlela yokukhiqiza:

Itholakala ngokuyi-hydrolysis ye-2,6-difluorobenzonitrile. Ukusabela kwenziwa ku-90% sulfuric acid ekushiseni kwe-hydrolysis okungu-70°C.
