Isingeniso
3,4-Difluoronitrobenzene: Isithako Esibalulekile Sokukhiqiza Imithi
I-3,4-I-Difluoronitrobenzene iyinhlanganisela ebalulekile yemvelo evame ukusetshenziswa njengesandulela noma esimaphakathi ekukhiqizweni kwemithi.Lesi sithako esisebenza ngezindlela eziningi saziwa nangokuthi i-fluoroaromatic, okusho ukuthi iqukethe kokubili i-fluorine namaqembu asebenzayo anephunga elimnandi.I-Fluoroaromatic compounds iyizisekelo ezibalulekile zokwakha izidakamizwa, izibulala-zinambuzane, namanye amakhemikhali emvelo.
Esinye sezicelo ezibaluleke kakhulu ze-3,4-difluoronitrobenzene njengesithako esisebenzayo semithi (API) ekukhiqizeni imithi ehlukahlukene.Le nhlanganisela isetshenziswa ekuhlanganiseni kwezidakamizwa eziningi, okuhlanganisa ama-antifungal agents, ama-antibiotics, izidakamizwa ezilwa nomdlavuza, nemithi elwa nokuvuvukala.Ama-substituents e-fluoro enza lesi sakhi siwusizo ikakhulukazi ekuklameni izidakamizwa ezingakhomba ngempumelelo amagciwane noma izinqubo ezithile ezibangela izifo.
I-3,4-Difluoronitrobenzene inezinye izakhiwo ezimbalwa eziyenza ibe isithako esikhangayo sokukhiqiza imithi.Isibonelo, i-compound inezinto ezinhle kakhulu zokuncibilika, ezivumela ukuthi zincibilike kalula kuhlu lwezincibilikizo kanye nama-reactants.Iphinde ibe nokuzinza okuhle kwe-thermal, okusho ukuthi ingakwazi ukumelana namazinga okushisa aphezulu kanye nezingcindezi ngesikhathi sokusabela kwamakhemikhali.Ukwengeza, le nhlanganisela kulula ukuyihlanganisa nokuyihlukanisa, okwenza ibe isithako esingabizi kakhulu ekuthuthukisweni kwezidakamizwa.
Ukubonakala kwe-3,4-difluoronitrobenzene kuwuketshezi oluphuzi olucacile, okwenza kube lula ukuphatha nokuthutha.Inhlanganisela ngokuvamile igcinwa ezitsheni ezingangeni moya ukuze kuvinjelwe i-oxidation nokungcola.Kufanele futhi igcinwe kude nokushisa namalangabi, njengoba ivutha futhi ivutha.
Sekukonke, i-3,4-difluoronitrobenzene iyinhlanganisela ewusizo ngendlela emangalisayo futhi eguquguqukayo ekukhiqizeni imithi.Izakhiwo nezici zayo eziyingqayizivele ziyenza ibe isithako esibalulekile ekuhlanganiseni uhla olubanzi lwemithi.Njengoba imboni yemithi iqhubeka nokukhula futhi ishintsha, isidingo se-3,4-difluoronitrobenzene kulindeleke ukuthi sikhuphuke, okuyenza ibe isithako esibalulekile sekusasa lokuthuthukiswa kwezidakamizwa.
