2 4-Difluorobiphenyl (CAS# 37847-52-2)

Isingeniso

2,4-Difluorobiphenyl. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2,4-difluorobiphenyl:

Ikhwalithi:

Ukubukeka: I-2,4-difluorobiphenyl iyikristalu engenambala noma impushana emhlophe.

Ayincibiliki emanzini ezingeni lokushisa lasekamelweni, kodwa ingancibilika kuzincibilikisi zemvelo ezifana ne-ethanol, i-ether, njll.

I-2,4-Difluorobiphenyl iyinhlanganisela ezinzile engangenwa ukushisa nokukhanya.

Sebenzisa:

I-2,4-Difluorobiphenyl isetshenziswa ngokuyinhloko njengento ebalulekile emaphakathi ekuhlanganiseni kwe-organic.

Kwamanye amadivaysi e-organic optoelectronic, i-2,4-difluorobiphenyl iphinde isetshenziswe njengezinto zamadivayisi afana ne-organic light-emitting diode (OLEDs).

Indlela:

I-2,4-Difluorobiphenyl ingalungiswa ngokusabela kwe-phenylacetylene ne-hydrogen fluoride. I-Phenylacetylene iqala ukusabela nge-hydrogen fluoride ukuze yakhe i-2,4-difluorobiphenyl, bese umkhiqizo ohlosiwe utholakala ngezinyathelo ezifanele zokuhlanza.

Enqubweni yokulungiselela, ukunakwa kufanele kukhokhwe ekulawuleni izinga lokushisa lokusebenza, ukukalwa kwama-reactants kanye nezimo zokusabela ukuze kuqinisekiswe ukuphepha nekhwalithi yomkhiqizo.

Ulwazi Lokuphepha:

I-2,4-Difluorobiphenyl iyinhlanganisela yobuthi obuphansi, kodwa isadinga ukuphathwa ngokuphepha. Izinto zokuzivikela ezinjengamagilavu ​​okuzivikela, izibuko, nezingubo kufanele zigqokwe lapho usebenzisa noma uhlangana ne-2,4-difluorobiphenyl.

Gwema ukuthinta isikhumba, amehlo kanye nomgudu wokuphefumula we-2,4-difluorobiphenyl, futhi ugeze ngamanzi amaningi uma kwenzeka ukuthintana ngephutha. Uma ubhekana nokungakhululeki okungapheli, kufanele ufune usizo lwezokwelapha ngokushesha.

Ngesikhathi sokugcina nokuthutha, i-2,4-difluorobiphenyl kufanele igcinwe ivaliwe ukuze kugwenywe ukuthintana nezinto ezifana nama-oxidants nama-acids aqinile/izisekelo.
