Nhanganyaya
2,5-Difluorobenzonitrile is an organic compound. Izvi zvinotevera sumo yezvimwe zvivakwa, kushandiswa, nzira dzekugadzirira uye ruzivo rwekuchengetedza ye2,5-difluorobenzonitrile:
Hunhu:
- 2,5-Difluorobenzonitrile ikristaro isina ruvara kune yakachenuruka uye inonhuwa.
- 2,5-difluorobenzonitrile inenge isinganyungudike mumvura patembiricha yekamuri, asi inonyungudika muorganic solvents senge ethanol, acetone, nezvimwe.
- Musanganiswa une kunhuhwirira kwakasimba.
Shandisa:
- 2,5-Difluorobenzonitrile inoshandiswa zvakanyanya mukugadzirwa kwechigadzirwa semakemikari reagent yekugadzirira mamwe maumbirwo emagetsi.
-Inowanzo shandiswa mukuita fluorination uye aromatization reactions nekuti kuiswa kwemaatomu efluorine kunogona kushandura maitiro emakomponi, kuwedzera hydrophobicity yavo uye kugadzikana kwemakemikari.
Nzira:
- 2,5-difluorobenzonitrile inogona kugadzirwa nekunhuhwirira kutsiva kuita. Nzira yekugadzirira yakajairika ndeyekuita para-dinitrobenzene ine nitrosamines yakagadziriswa ne cuprous chloride uye hydrofluoric acid kuti iwane 2,5-difluorobenzonitrile.
Zvekuchengetedza
- Paunenge uchibata 2,5-difluorobenzonitrile, pfeka midziyo yekudzivirira yakakodzera semakemikari ekudzivirira magirovhosi, magirazi, uye jasi rebhu.
-Ikomboni inogumbura inogona kukonzera kushatirwa kumaziso, ganda, uye nzira yekufema.
- Inhalation yehuputi hwayo kana guruva, ganda uye kuonana kweziso kunofanirwa kudzivirirwa panguva yekubata.
- Kuchenjerera kunofanira kubhadharwa kune moto uye kuputika matanho ekudzivirira panguva yekuchengetedza uye kushandiswa, uye kuchengetedza kure nemoto uye oxidants.
