Isingeniso
I-3-nitro-4-bromobenzoic acid iyinhlanganisela yemvelo enefomula ethi C7H4BrNO4.
Imvelo:
-Ukubukeka: Ikristalu engenambala noma i-crystalline powder ephuzi ekhanyayo.
-indawo yokuncibilika: 215-218 ℃.
-Ukunyibilika: Ukuncibilika emanzini kuncane, kuncibilika ku-ethanol, i-ether ne-chloroform nezinye izincibilikisi eziphilayo.
Sebenzisa:
I-3-nitro-4-bromobenzoic acid iyingxenye ebalulekile ye-organic synthesis, esetshenziswa kabanzi embonini yokwenziwa kwemithi kanye nodayi.
-Ukuhlanganiswa kwezidakamizwa: kungasetshenziswa njengesandulela sokuhlanganiswa kwezidakamizwa ezingezona ukuvuvukala nezinye izidakamizwa.
-Imboni ye-Dye: ingasetshenziselwa odayi bokwenziwa kanye nezingulube.
Indlela Yokulungiselela:
I-3-nitro-4-bromobenzoic acid ingalungiswa nge-nitrate ye-4-bromobenzoic acid. Izinyathelo eziqondile zimi kanje:
1. Chaza i-4-bromobenzoic acid kwisisombululo esixubile se-nitric acid ne-glacial acetic acid.
2. Govuza ingxube yokusabela ekushiseni okuphansi.
3. Umkhiqizo owenziwe engxubeni yokusabela uyahlungwa futhi ugezwe, bese uyomiswa ukuze uthole i-3-nitro-4-bromobenzoic acid.
Ulwazi Lokuphepha:
I-3-nitro-4-bromobenzoic acid inomphumela ovuselelayo esikhumbeni namehlo, futhi kufanele ihlanzwe ngokugcwele ngemva kokuxhumana. Ngesikhathi sokusebenzisa nokugcina, gwema ukuhogela uthuli lwayo futhi ugqoke izinto zokuzivikela uma kunesidingo. Ngaphezu kwalokho, i-3-nitro-4-bromobenzoic acid ingase ibangele ukulimala emvelweni, ngakho-ke kufanele kuqashelwe ukuhambisana nemithetho efanele yokuphepha kwemvelo.
