- I-4-Iodo-3-nitrobenzoic acid isetyenziswa kakhulu njengento ephakathi kwi-organic synthesis.
-Yinto ebalulekileyo ekrwada yokwenziwa kweziyobisi kunye ne-pesticides.
-Ingasetyenziselwa ukuhlanganiswa kokukhanya okukhupha ukukhanya kwizixhobo ze-organic electroluminescent (OLED).
Indlela yokulungiselela:
Kukho iindlela ezininzi zokulungiselela i-4-Iodo-3-nitrobenzoic acid, enye esetyenziswa ngokuqhelekileyo ukufumana nge-nitrate ye-iodobenzoic acid. Amanyathelo athile okulungiselela angoluhlobo lulandelayo:
1. nyibilikisa iodobenzoic acid kwi-nitric acid egxininisiweyo.
2. Kancinci yongeza i-asidi ye-sulfuric egxininisiweyo kwiqondo lokushisa eliphantsi kwaye uvuselele ukuphendula.
3. Emva kokuba i-reaction iqhutywe ixesha elithile, imveliso kwisisombululo sokuphendula iyahlukana ngokuhluzwa okanye i-crystallization.
4. I-4-Iodo-3-nitrobenzoic acid ekugqibeleni yahlanjululwa ngokuhlamba nge-solvent efanelekileyo kunye ne-crystallization.
Ulwazi ngoKhuseleko:
- I-4-Iodo-3-nitrobenzoic acid i-organic compound. Amanyathelo okuzikhusela kufuneka athathwe xa uyisebenzisa, njengokunxiba iiglavu kunye neeglasi zokukhusela amehlo.
-I-compound i-corrosion kumlinganiselo othile, ugweme ukudibanisa kwesikhumba kunye nokuphefumla.
-Ngexesha lokusebenza, qaphela ukuba ugweme ukudibanisa nee-oxidants ezinamandla kunye nee-agent zokunciphisa ukuphepha ukuphendula okuyingozi.
-Ngexesha lokugcinwa, kufuneka ligcinwe kwindawo epholileyo, eyomileyo, enomoya, ehlulwe kwizinto ezinokutsha kunye nezinto ezinokutsha.
-Ukuba ukudibana kwenzeka, ngokukhawuleza uhlambulule indawo echaphazelekayo ngamanzi amaninzi kwaye ufune uncedo lwezonyango.
