Isingeniso

I-3,4-Difluorobromobenzene iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

Ukubukeka: 3,4-Difluorobromobenzene uketshezi olungenambala ukuya kokuphuzi ngokukhanyayo.

Ukuminyana: cishe. 1.65 g/cm³

Ukunyibilika: I-3,4-difluorobromobenzene iyancibilika kwezinye izinyibilikisi zemvelo futhi cishe ayincibiliki emanzini.

 

Sebenzisa:

Imboni yezogesi: ngenxa yezakhiwo zayo ezinhle zikagesi, i-3,4-difluorobromobenzene ivamise ukusetshenziswa njengengxenye yezinto ze-organic semiconductor.

 

Indlela:

Indlela yokulungiselela i-3,4-difluorobromobenzene ihlanganisa lezi zinyathelo ezilandelayo:

Okokuqala, i-bromobenzene ne-bromoflurane ziyasabela ukukhiqiza i-2,3,4,5-tetrabromofluorobenzene.

2,3,4,5-tetrabromofluorobenzene bese isabela nge-hydrofluoric acid ukuze kutholwe i-3,4-difluorobromobenzene.

 

Ulwazi Lokuphepha:

I-3,4-I-Difluorobromobenzene inobuthi futhi kufanele kuthathwe ukunakekelwa ukuze kugwenywe ukuthintana nesikhumba kanye nokuhogela umhwamuko waso.

Izimiso ezifanele zaselabhorethri kanye nezinyathelo zokuzivikela zomuntu siqu njengokugqoka amagilavu ​​okuzivikela afanelekile, izibuko, namamaski okuzivikela kufanele kulandelwe ngesikhathi sokusetshenziswa.

Lapho uyigcina, kufanele igcinwe kude nemithombo yomlilo nama-oxidants, futhi ugweme ukuthintana nama-asidi aqinile noma ama-alkali.

Lapho kulahlwa imfucuza, kufanele ilahlwe ngokuhambisana nemithetho nemithethonqubo efanele ukuze kugwenywe ukungcoliswa kwemvelo.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
