Isingeniso

I-O-difluorobenzene iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-o-difluorobenzene:

 

Ikhwalithi:

- Ukubukeka: I-O-difluorobenzene uketshezi olungenambala noma ikristalu emhlophe.

- Ukunyibilika: I-O-difluorobenzene iyancibilika kuzincibilikisi zemvelo ezifana notshwala, i-ethers ne-benzene.

 

Sebenzisa:

- I-O-difluorobenzene ingasetshenziswa njengento yokuqala futhi ephakathi ku-organic synthesis, futhi isetshenziswa kakhulu emikhakheni yezemithi, yezibulala-zinambuzane kanye nodayi.

- Ingasetshenziswa futhi njengesithasiselo kuma-coatings, ama-solvents nama-lubricant.

- I-O-difluorobenzene ingasetshenziswa futhi embonini ye-electronics, isb njengengxenye yezinto eziwuketshezi zekristalu.

 

Indlela:

- Kunezindlela ezimbili eziyinhloko zokwenza i-o-difluorobenzene: ukusabela kwe-fluorine compounds ne-benzene kanye nokusabela okukhethiwe kwe-fluorination ye-fluorinated benzene.

- Ukusabela kwezinhlanganisela ze-fluorine nge-benzene kuvamile, futhi i-o-difluorobenzene ingatholwa ngokufakwa kwe-chlorobenzene nge-fluorine gas.

- I-fluorination ekhethiwe ye-benzene eyi-fluorinated idinga ukusetshenziswa kwama-reagents akhethiwe e-fluorinating ukuze kuhlanganiswe.

 

Ulwazi Lokuphepha:

- Ukuchayeka ku-o-difluorobenzene kungase kubangele ukucasuka esikhumbeni, emehlweni nasohlelweni lokuphefumula, futhi kufanele kuthathwe izinyathelo zokuphepha.

- Gqoka izibuko zokuzivikela, amagilavu ​​nezingubo zokusebenza lapho usebenzisa i-o-difluorobenzene, futhi ulondoloze indawo enomoya omuhle.

- Gwema umlilo namazinga okushisa aphezulu, futhi ugcine endaweni epholile, eyomile.

- Ngaphambi kokusebenzisa noma ukuphatha i-o-difluorobenzene, funda futhi ulandele iziqondiso ezifanele zokuphatha ukuphepha.
