3,4-Difluoronitrobenzene: Isithako esineXabiso sokuVelisa aMayeza
I-3,4-i-Difluoronitrobenzene yinto exabisekileyo yezinto eziphilayo esetyenziswa ngokuqhelekileyo njenge-precursor okanye ephakathi kwimveliso yamayeza.Esi sithako sisebenza ngeendlela ezininzi sikwabizwa ngokuba yi-fluoroaromatic, nto leyo ethetha ukuba iqulethe zombini amaqela efluorine kunye nevumba elimnandi elisebenzayo.Iikhompawundi zeFluoroaromatic zizinto ezibalulekileyo zokwakha ekwenziweni kwamachiza, izitshabalalisi, kunye nezinye iikhemikhali eziphilayo.
Esinye sezicelo ezibalulekileyo ze-3,4-difluoronitrobenzene njengesithako esisebenzayo seyeza (API) ekuveliseni amayeza ahlukeneyo.Le khompawundi isetyenziselwa ukuhlanganiswa kwenani lamachiza, kubandakanywa i-antifungal agents, i-antibiotics, i-anti-cancer drug, kunye neyeza ezichasayo.Amalungu e-fluoro enza le khompawundi ibe luncedo ngakumbi ekuyileni amachiza anokuthi ajolise ngokufanelekileyo kwiintsholongwane ezibangela isifo okanye iinkqubo.
I-3,4-Difluoronitrobenzene inezinye iipropati ezininzi ezenza ukuba ibe sisithako esinomtsalane kwimveliso yamayeza.Ngokomzekelo, i-compound ineempawu ezintle zokunyibilika, ezivumela ukuba zinyibilike ngokulula kuluhlu lwe-solvents kunye ne-reactants.Kwakhona kunozinzo oluhle lwe-thermal, oku kuthetha ukuba inokumelana nokushisa okuphezulu kunye noxinzelelo ngexesha lokuphendula kweekhemikhali.Ukongeza, le khompawundi kulula ukuyidibanisa kwaye yahlula, nto leyo eyenza ukuba ibe sisithako esineendleko eziphezulu kuphuhliso lwamachiza.
Ukubonakala kwe-3,4-difluoronitrobenzene i-liquid ecacileyo ephuzi, eyenza kube lula ukuphatha kunye nokuthutha.Ikhompawundi idla ngokugcinwa kwizikhongozeli ezingangeni moya ukukhusela i-oxidation kunye nokungcoliseka.Kufuneka kwakhona igcinwe kude nobushushu kunye namalangatye, njengoko inokutsha kwaye iyatsha.
Lilonke, i-3,4-difluoronitrobenzene iyikhompawundi eluncedo kakhulu kwaye eguquguqukayo kwimveliso yamayeza.Iimpawu zayo ezizodwa kunye neempawu zenza ukuba ibe yinto ebaluleke kakhulu yokudibanisa uluhlu olubanzi lwamayeza.Njengoko ishishini loxubo mayeza liqhubeka nokukhula kwaye livela, imfuno ye-3,4-difluoronitrobenzene kulindeleke ukuba inyuke, nto leyo eyenza ukuba ibe sisithako esibalulekileyo kwikamva lophuhliso lwamachiza.
