Intshayelelo
I-4-nitrophenylhydrazine hydrochloride. Oku kulandelayo sintshayelelo kubume bayo, ukusetyenziswa, indlela yokulungiselela kunye nolwazi lokhuseleko:
Umgangatho:
- I-4-Nitrophenylhydrazine hydrochloride yinto eqinileyo yecrystalline etyheli enyibilikayo emanzini.
I-oxidizing kakhulu kwaye iyadubula, ngoko yiphathe ngononophelo.
Sebenzisa:
- I-4-Nitrophenylhydrazine hydrochloride isetyenziswa ngokuqhelekileyo njengendawo ephakathi kwizinto ezinamandla kakhulu kunye neziqhushumbisi.
- Ingasetyenziswa ekulungiseleleni ezinye iikhompawundi nitro-equlethwe iqela.
Indlela:
- Indlela eqhelekileyo yokulungiselela i-4-nitrophenylhydrazine hydrochloride ifunyenwe nge-nitrification.
- Dissolve phenylhydrazine in an acidic solvent kwaye wongeze inani elifanelekileyo le-nitric acid.
- Ekupheleni kokuphendula, imveliso ifakwe kwi-crystallized ngendlela ye-hydrochloric acid.
Ulwazi ngoKhuseleko:
- I-4-Nitrophenylhydrazine hydrochloride yikhompawundi engazinzanga kakhulu kwaye iqhuma kwaye akufanele iphendule ngobundlobongela kunye nezinye izinto okanye iimeko.
- Ngexesha lokuphatha kunye nokugcinwa, kubalulekile ukulandela iinkqubo ezifanelekileyo zokusebenza zokhuseleko kunye nokugqoka izixhobo ezifanelekileyo zokukhusela.
- Xa uqhuba iimvavanyo okanye ukusetyenziswa kwemizi-mveliso, isixa kunye neemeko zokusetyenziswa kwayo zilawulwa ngokungqongqo ukukhusela iingozi.
- Xa ulahla okanye ulahla into, imithetho yendawo, imimiselo kunye nemimiselo kufuneka ilandelwe.
