Isingeniso
I-3,5-Difluorobenzonitrile iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso kwezinye izakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-3,5-difluorobenzonitrile:
Ikhwalithi:
- Ukubukeka: 3,5-Difluorobenzonitrile uketshezi olungenambala kuya kokuphuzi okuphaphathekile.
- Ukunyibilika: Kuncibilika kuzincibilikisi eziningi eziphilayo njenge-ethanol, i-ether, ne-chloroform.
Sebenzisa:
- I-3,5-Difluorobenzonitrile isetshenziswa ngokuyinhloko njengendawo ephakathi ku-organic synthesis.
- Ingasetshenziswa futhi njengamakhemikhali angaba khona embonini ye-elekthronikhi ekukhiqizeni odayi nezinto zokwenziwa.
Indlela:
- Indlela eyinhloko yokulungiselela i-3,5-difluorobenzonitrile itholakala ngokusabela kwe-3,5-difluorophenyl bromide kanye ne-cyanide yethusi ngaphansi kwezimo ezifanele.
Ulwazi Lokuphepha:
- 3,5-I-Difluorobenzonitrile iyacasula futhi idla, futhi izinyathelo ezifanele zokuphepha ezifana nokugqoka amagilavu okuzivikela kanye nezibuko kufanele zithathwe ngesikhathi sokusetshenziswa.
- Gwema ukuthintana ngqo nesikhumba kanye nokuhogela umhwamuko waso, futhi usebenze endaweni engenawo umoya.
- Lapho uphatha futhi ugcina i-3,5-difluorobenzonitrile, kufanele kuqashelwe ukugwema ukuthintana nama-oxidants, ama-alkali anamandla nezinye izinto ukuvimbela ukuvela kokusabela okuyingozi.
- Bheka ezincwadini zokuphepha ezifanele kanye neziqondiso zokuphatha lapho usebenzisa noma uphatha lesi sakhiwo, futhi ulandele ngokuqinile imithethonqubo efanele.
