Isingeniso
I-2,6-Difluorobenzonitrile, eyaziwa nangokuthi i-2,6-difluorobenzonitrile, iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: 2,6-Difluorobenzonitrile uketshezi olungenambala noma i-crystal emhlophe.
- Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo.
Sebenzisa:
- I-2,6-Difluorobenzonitrile ivame ukusetshenziswa njengento ebalulekile ekuhlanganiseni kwe-organic synthesis, isibonelo njengento yokuqala yokwenziwa kwamanye ama-organic compounds.
Indlela:
- Indlela yokulungiselela i-2,6-difluorobenzonitrile itholakala ngokuyinhloko ngokusabela kwe-2,6-difluorobenzyl utshwala ne-sodium cyanide phambi kwe-catalyst alkaline.
- Izinyathelo eziqondile zifaka ukusabela kwe-2,6-difluorobenzyl alcohol ne-sodium cyanide ngaphansi kwezimo ze-alkaline, okulandelwa yi-acidification ukuze kutholwe umkhiqizo we-2,6-difluorobenzonitrile.
Ulwazi Lokuphepha:
- I-2,6-difluorobenzonitrile inobuthi obuphansi, kodwa kusafanele kuthathwe ukunakekelwa ukuze kugwenywe ukuthintana ngqo nesikhumba, amehlo, kanye nomgudu wokuphefumula.
- Izinqubo zokuphepha ezifanele kanye nempahla yokuvikela efanele kufanele ilandelwe lapho isetshenziswa noma igcinwa.
- Uma inhlanganisela ithintwe ngephutha noma ihogelwe, kufanele ihlanzwe noma ifakwe umoya ngokushesha futhi kufuneke ukunakekelwa kwezempilo ngokushesha.
