Isingeniso
I-2,5-bis(trifluoromethyl)benzoic acid iyinhlanganisela yemvelo enefomula yamakhemikhali C9H4F6O2. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:
Imvelo:
- 2,5-bis(trifluoromethyl)benzoic acid iyikristale engenambala ukuya kokuphuzi okuphaphathekile noma okuqinile okuyimpuphu.
-Cishe ayincibiliki emanzini ezingeni lokushisa lasekamelweni, kodwa incibilika kuzincibilikisi zemvelo ezifana ne-ether ne-dichloromethane.
- Inephunga elinamandla elinukayo nelinukayo.
Sebenzisa:
- I-2,5-bis(trifluoromethyl)benzoic acid iyi-reagent evame ukusetshenziswa ku-organic synthesis, engasetshenziswa ukuhlanganisa izinhlanganisela ezifana nezidakamizwa, odayi nezinto zokwakha.
-Ingasetshenziswa njenge-catalyst ye-organic synthesis reactions, njengokusabela kwe-aromatization kanye nokusabela kwe-carboxylation.
-Ngaphezu kwalokho, isetshenziselwa ukulungiswa kwezinto ze-elekthronikhi kanye nokuguqulwa kwendawo yezinto ezibonakalayo.
Indlela Yokulungiselela:
- I-2,5-bis(trifluoromethyl)benzoic acid ingahlanganiswa ngokusabela i-2,5-difluoromethylbenzoic acid ne-trifluoromethylating reagent (njenge-trifluoromethyl chloride).
-Lokhu kusabela ngokuvamile kwenziwa ngaphansi komkhathi ongasebenzi futhi kusebenzisa i-catalyst ngaphansi kwezimo ezine-acidic noma eziyisisekelo.
Ulwazi Lokuphepha:
- I-2,5-bis(trifluoromethyl)benzoic acid igqwala kakhulu futhi ingabangela ukucasuka okukhulu kanye nomonakalo lapho uthinta isikhumba namehlo.
-Gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko nezingubo zokuzivikela ngesikhathi usebenza.
-Le nhlanganisela kufanele igcinwe kude nama-ejenti omlilo kanye ne-oxidizing, futhi ifakwe esitsheni esivaliwe ukuvimbela ukuthintana nomoya namanzi.
-Izindlela zokuphepha ezifanele zaselabhorethri yamakhemikhali kufanele zilandelwe ngesikhathi sokusetshenziswa nokugcinwa.
