Intshayelelo

2,4-Difluorobiphenyl. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2,4-difluorobiphenyl:

Umgangatho:

Imbonakalo: I-2,4-difluorobiphenyl yikristale engenambala okanye umgubo omhlophe.

Ayinyibiliki emanzini kwiqondo lobushushu begumbi, kodwa inokunyibilika kwizinyibilikisi eziphilayo ezifana ne-ethanol, i-ether, njl.

I-2,4-i-Difluorobiphenyl i-compound ezinzile engathinteki ukushisa kunye nokukhanya.

Sebenzisa:

I-2,4-Difluorobiphenyl isetyenziswa kakhulu njengento ebalulekileyo ephakathi kwi-organic synthesis.

Kwezinye izixhobo ze-organic optoelectronic, i-2,4-difluorobiphenyl ikwasetyenziswa njengesixhobo sezixhobo ezifana ne-organic light-emitting diodes (OLEDs).

Indlela:

I-2,4-Difluorobiphenyl inokulungiswa ngokusabela kwe-phenylacetylene kunye ne-hydrogen fluoride. I-Phenylacetylene iqala ukusabela nge-hydrogen fluoride ukwenza i-2,4-difluorobiphenyl, kwaye ke imveliso ekujoliswe kuyo ifunyenwe ngamanyathelo afanelekileyo okucoca.

Kwinkqubo yokulungiselela, ingqalelo kufuneka ihlawulwe ekulawuleni ukushisa okusebenzayo, ukulinganiswa kwee-reactants kunye neemeko zokuphendula ukuqinisekisa ukhuseleko kunye nomgangatho wemveliso.

Ulwazi ngoKhuseleko:

I-2,4-Difluorobiphenyl yinto ephantsi-ityhefu, kodwa isafuna ukuphathwa ngokukhuselekileyo. Izixhobo zokukhusela zomntu ezifana neeglavu zokukhusela, iiglavu kunye neegawuni kufuneka zinxitywe xa usebenzisa okanye udibana ne-2,4-difluorobiphenyl.

Gwema ukudibana nolusu, amehlo kunye nokuphefumula kwe-2,4-difluorobiphenyl, kwaye uhlambulule ngamanzi amaninzi xa udibana nengozi. Ukuba ufumana ukungakhululeki okuzingisileyo, kufuneka ufune unyango ngokukhawuleza.

Ngexesha lokugcinwa kunye nokuthutha, i-2,4-difluorobiphenyl kufuneka igcinwe ivaliwe ukuphepha ukudibanisa nezinto ezifana ne-oxidants kunye ne-acids eqinile / iziseko.

Ngaphambili: 2 2 2-Trifluoroethylamine hydrochloride (CAS# 373-88-6)

Okulandelayo: 2-Mercaptonicotinic acid (CAS# 38521-46-9)
