Kapangidwe ka mankhwala:

2,6-difluorobenzamide ndi kristalo woyera wonga ufa, mp143 ~ 145℃, wosasungunuka m'madzi

Ntchito:

Mankhwalawa amagwiritsidwa ntchito ngati njira yopangira mankhwala ophera tizilombo a fluorobenzoyl urea. Angagwiritsidwe ntchito popanga mankhwala osiyanasiyana ophera tizilombo ndi ma acaricides monga hexaflumuron, chlorfenapyr, ndi diflubenzuron. Amagwiritsidwanso ntchito mu mankhwala ndi zinthu zamadzimadzi za kristalo. Mankhwalawa ali mu mbiya ya khadibodi yokhala ndi thumba la pulasitiki, yolemera 25kg pa mbiya iliyonse.

Njira yopangira:

Imapezeka mwa hydrolysis ya 2,6-difluorobenzonitrile. Yankho lake limachitika mu 90% sulfuric acid pa kutentha kwa hydrolysis kwa 70°C.
