Isingeniso

I-Nitrophenylhydrazine, ifomula yamakhemikhali C6H7N3O2, iyinhlanganisela yezinto eziphilayo.

 

Sebenzisa:

I-Nitrophenylhydrazine inokusetshenziswa okuningi embonini yamakhemikhali, ikakhulukazi okuhlanganisa izici ezilandelayo:

1. Izinto zokusetshenziswa eziyisisekelo: zingasetshenziselwa ukukhiqiza odayi, odayi be-fluorescent kanye ne-organic synthesis intermediates namanye amakhemikhali.

2. iziqhumane: zingasetshenziselwa ukulungisa iziqhumane, imikhiqizo ye-pyrotechnical nama-propellants nezinye iziqhumane.

 

Indlela Yokulungiselela:

Ukulungiswa kwe-nitrophenylhydrazine kuvame ukufezwa nge-nitric acid esterification. Izinyathelo ezithile zimi kanje:

1. Chaza i-phenylhydrazine ku-nitric acid.

2. Ngaphansi kwezinga lokushisa elifanele nesikhathi sokusabela, i-nitrous acid ku-nitric acid ihlangana ne-phenylhydrazine ukukhiqiza i-nitrophenylhydrazine.

3. Ukuhlunga nokugeza kunikeza umkhiqizo wokugcina.

 

Ulwazi Lokuphepha:

I-nitrophenylhydrazine iyinhlanganisela evuthayo, okulula ukuyibangela ukuqhuma lapho ibekwe elangabini elivulekile noma izinga lokushisa eliphezulu. Ngakho-ke, izinyathelo ezifanele zokuvimbela umlilo nokuqhuma ziyadingeka lapho ugcina futhi uphatha i-nitrophenylhydrazine. Ngaphezu kwalokho, i-nitrophenylhydrazine nayo iyacasula futhi inomphumela othile olimazayo emehlweni, esikhumbeni nasemgudwini wokuphefumula. Kuyadingeka ukugqoka izinto zokuzivikela ezifanele ngesikhathi sokusebenza. Ekusetshenzisweni nasekulahlweni, ukuthobela ngokuqinile imithethonqubo efanele yokuphepha kanye nemihlahlandlela yokusebenza, ukuqinisekisa ukuphepha kwabantu kanye nemvelo.
