Mawu Oyamba
2,5-Difluorobenzonitrile ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 2,5-difluorobenzonitrile:
Ubwino:
- 2,5-Difluorobenzonitrile ndi kristalo wachikasu wotuwa wopanda utoto wokhala ndi fungo loyipa.
- 2,5-difluorobenzonitrile pafupifupi insoluble m'madzi kutentha firiji, koma sungunuka mu zosungunulira organic monga Mowa, acetone, etc.
- Ndi chinthu chomwe chimakhala ndi fungo lamphamvu.
Gwiritsani ntchito:
- 2,5-Difluorobenzonitrile amagwiritsidwa ntchito kwambiri popanga organic synthesis ngati mankhwala opangira mankhwala opangira mankhwala ena.
- Nthawi zambiri amagwiritsidwa ntchito muzochita za fluorination ndi kununkhira kwake chifukwa kuyambitsa maatomu a fluorine kumatha kusintha mawonekedwe azinthu, kukulitsa hydrophobicity ndi kukhazikika kwamankhwala.
Njira:
- 2,5-difluorobenzonitrile ikhoza kukonzedwa ndi kununkhira kolowa m'malo. Njira yodziwira yodziwika bwino ndikuchita para-dinitrobenzene ndi nitrosamines wopangidwa ndi cuprous chloride ndi hydrofluoric acid kuti apeze 2,5-difluorobenzonitrile.
Zambiri Zachitetezo:
- Pogwira 2,5-difluorobenzonitrile, valani zida zodzitetezera zoyenera monga magolovesi oteteza mankhwala, magalasi, ndi malaya a labu.
- Ndi mankhwala omwe amachititsa kuti maso, khungu, ndi kupuma.
- Kukoka mpweya wake kapena fumbi, khungu ndi kuyang'ana maso kuyenera kupewedwa mukamagwira.
- Muyenera kuyang'anitsitsa njira zopewera moto ndi kuphulika panthawi yosungira ndikugwiritsa ntchito, komanso kukhala kutali ndi magwero a moto ndi okosijeni.
