Mawu Oyamba
O-difluorobenzene ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha o-difluorobenzene:
Ubwino:
- Maonekedwe: O-difluorobenzene ndi madzi opanda mtundu kapena kristalo woyera.
- Kusungunuka: O-difluorobenzene imasungunuka mu zosungunulira za organic monga ma alcohols, ethers ndi benzene.
Gwiritsani ntchito:
- O-difluorobenzene angagwiritsidwe ntchito ngati zoyambira komanso zapakatikati pakupanga organic, ndipo amagwiritsidwa ntchito kwambiri m'minda yamankhwala, mankhwala ophera tizilombo ndi utoto.
- Itha kugwiritsidwanso ntchito ngati chowonjezera mu zokutira, zosungunulira ndi mafuta.
- O-difluorobenzene itha kugwiritsidwanso ntchito pamakampani opanga zamagetsi, mwachitsanzo ngati gawo la zinthu zamadzimadzi za kristalo.
Njira:
- Pali njira ziwiri zazikulu zopangira o-difluorobenzene: zomwe fluorine imapangidwa ndi benzene komanso kusankha fluorination ya fluorinated benzene.
- Zochita za fluorine zopangidwa ndi benzene ndizofala, ndipo o-difluorobenzene imatha kupezeka ndi fluorination ya chlorobenzene ndi mpweya wa fluorine.
- Kusankha fluorination wa fulorosenti benzene kumafuna kugwiritsa ntchito kusankha fluorinating reagents kuti kaphatikizidwe.
Zambiri Zachitetezo:
- Kuwonetsedwa ndi o-difluorobenzene kungayambitse kuyabwa pakhungu, maso ndi kupuma, ndipo kusamala kuyenera kutengedwa.
- Valani magalasi odzitchinjiriza, magolovu ndi zovala zogwirira ntchito mukamagwiritsa ntchito o-difluorobenzene, komanso kukhala ndi malo abwino olowera mpweya.
- Khalani kutali ndi moto ndi kutentha kwambiri, ndipo sungani pamalo ozizira, owuma.
- Musanagwiritse ntchito kapena kugwira o-difluorobenzene, werengani ndikutsatira malangizo oyendetsera chitetezo.
