Mawu Oyamba
2,6-Difluorobenzonitrile, yomwe imadziwikanso kuti 2,6-difluorobenzonitrile, ndi mankhwala achilengedwe. Zotsatirazi ndizofotokozera za chikhalidwe chake, ntchito, njira yokonzekera ndi chidziwitso cha chitetezo:
Ubwino:
- Maonekedwe: 2,6-Difluorobenzonitrile ndi madzi opanda mtundu kapena kristalo woyera.
- Kusungunuka: Kusungunuka mu zosungunulira za organic.
Gwiritsani ntchito:
- 2,6-Difluorobenzonitrile nthawi zambiri amagwiritsidwa ntchito ngati chinthu chofunika kwambiri pakupanga organic synthesis, mwachitsanzo monga chiyambi chopangira zinthu zina.
Njira:
- Njira yokonzekera 2,6-difluorobenzonitrile imapezeka makamaka ndi zomwe 2,6-difluorobenzyl mowa ndi sodium cyanide pamaso pa chothandizira zamchere.
- Masitepe enieni akuphatikizapo zomwe 2,6-difluorobenzyl mowa ndi sodium cyanide pansi pa zinthu zamchere, zotsatiridwa ndi acidification kuti mupeze mankhwala a 2,6-difluorobenzonitrile.
Zambiri Zachitetezo:
- 2,6-difluorobenzonitrile ili ndi kawopsedwe kakang'ono, koma chisamaliro chiyenera kutengedwa kuti tipewe kukhudzana mwachindunji ndi khungu, maso, ndi kupuma.
- Njira zoyenera zotetezera ndi zida zodzitetezera ziyenera kutsatiridwa zikagwiritsidwa ntchito kapena kusungidwa.
- Mankhwalawa akakhudzidwa mwangozi kapena kukomoka, amayenera kutsukidwa kapena kutulutsa mpweya nthawi yomweyo ndipo chithandizo chamankhwala chiyenera kufunidwa mwachangu.
