Isingeniso
I-2,5-Difluorobenzonitrile iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso kwezinye izakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2,5-difluorobenzonitrile:
Ikhwalithi:
- 2,5-Difluorobenzonitrile iyikristalu engenambala ukuya kokuphuzi okuphaphathekile enephunga elimnandi.
- 2,5-difluorobenzonitrile cishe ayincibiliki emanzini ngamazinga okushisa asekamelweni, kodwa incibilika kuzincibilikisi eziphilayo njenge-ethanol, i-acetone, njll.
- Kuyinhlanganisela enephunga elimnandi elinamandla.
Sebenzisa:
- I-2,5-Difluorobenzonitrile isetshenziswa kabanzi ku-organic synthesis njenge-reagent yamakhemikhali yokulungiswa kwamanye ama-organic compounds.
- Ivame ukusetshenziswa ekuphenduleni kwe-fluorination kanye nokusabela kwe-aromatization ngoba ukwethulwa kwama-athomu e-fluorine kungashintsha izakhiwo zenhlanganisela, kwandise i-hydrophobicity yazo kanye nokuzinza kwamakhemikhali.
Indlela:
- I-2,5-difluorobenzonitrile ingalungiswa ngokusabela okunephunga elimnandi. Indlela evamile yokulungiselela iwukusabela i-para-dinitrobenzene nama-nitrosamine acutshungulwa yi-cuprous chloride ne-hydrofluoric acid ukuze kutholwe i-2,5-difluorobenzonitrile.
Ulwazi Lokuphepha:
- Lapho uphatha i-2,5-difluorobenzonitrile, gqoka izinto zokuzivikela ezifanele njengamagilavu okuvikela amakhemikhali, izibuko, nejazi laselabhu.
- Kuyinhlanganisela ecasulayo engase ibangele ukucasuka emehlweni, isikhumba, kanye nomgudu wokuphefumula.
- Ukuhogela umhwamuko noma uthuli, isikhumba kanye nokuthintana kwamehlo kufanele kugwenywe ngesikhathi sokuphatha.
- Kufanele kuqashelwe izinyathelo zokuvimbela umlilo nokuqhuma ngesikhathi sokugcinwa kanye nokusetshenziswa, futhi kude nemithombo yomlilo nama-oxidants.
