Isingeniso

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

 

Ikhwalithi:

- Ukubukeka: I-O-dibromobenzene iyikristalu engenambala noma okuqinile okumhlophe.

- Ukunyibilika: I-O-dibromobenzene iyancibilika kwezinye izinyibilikisi zemvelo, njenge-benzene notshwala.

 

Sebenzisa:

- Izinto ze-elekthronikhi ze-Organic: i-o-dibromobenzene ingasetshenziswa ekulungiseni izinto ze-organic optoelectronic, izibonisi zekristalu eliwuketshezi, njll.

 

Indlela:

Indlela eyinhloko yokulungiselela i-o-dibromobenzene itholakala ngokusabela esikhundleni se-bromobenzene. Indlela yokuhlanganisa evame ukusetshenziswa ukuncibilikisa i-benzene engxubeni ye-ferrous bromide ne-dimethyl sulfoxide bese isabela ezingeni lokushisa elifanele ukuze kutholwe i-o-dibromobenzene.

 

Ulwazi Lokuphepha:

- I-O-dibromobenzene inobuthi obuthile kanye nedatha yobuthi ethize idinga ukuhlolwa ngakunye.

- Gqoka amagilavu ​​nezibuko lapho usebenzisa i-o-dibromobenzene ukuvikela isikhumba namehlo akho.

- Gwema ukuhogela umhwamuko we-o-dibromobenzene noma ukuwufafaza emehlweni nasesikhumbeni.

- Gwema ukuthintana phakathi kwe-o-dibromobenzene nama-oxidants aqinile, ukuthungela kanye namazinga okushisa aphezulu.

- Ngesikhathi sokusetshenziswa nokugcinwa, kufanele kuqashelwe izinyathelo zokuvimbela umlilo nokuqhuma ukuze kugcinwe umoya omuhle.

- Lapho silahla imfucuza, sizothobela imithetho nemithethonqubo yendawo yendawo futhi sithathe izinyathelo ezifanele zokulahla imfucuza.
