Okwu mmalite
Nitrophenylhydrazine, usoro kemịkalụ C6H7N3O2, bụ ngwakọta organic.
Jiri:
Nitrophenylhydrazine nwere ọtụtụ ojiji na ụlọ ọrụ kemịkalụ, ọkachasị gụnyere akụkụ ndị a:
1. ihe ndị bụ isi: enwere ike iji mepụta akwa, fluorescent dyes na organic synthesis intermediates na ndị ọzọ chemicals.
2. ihe mgbawa: enwere ike iji ya mee nkwadebe nke ihe mgbawa, ngwaahịa pyrotechnical na ndị na-emepụta ihe na ihe mgbawa ndị ọzọ.
Ụzọ nkwadebe:
Nkwadebe nke nitrophenylhydrazine na-enwetakarị site na nitric acid esterification. Usoro ndị akọwapụtara bụ ndị a:
1. Igbari phenylhydrazine na nitric acid.
2. N'okpuru okpomọkụ kwesịrị ekwesị na oge mmeghachi omume, nitrous acid na nitric acid na-emeghachi omume na phenylhydrazine iji mepụta nitrophenylhydrazine.
3. Nzacha na ịsacha na-enye ngwaahịa ikpeazụ.
Ozi nchekwa:
nitrophenylhydrazine bụ ihe na-ere ọkụ, nke dị mfe ime ka mgbawa mgbe ọkụ na-emeghe ma ọ bụ okpomọkụ dị elu. Ya mere, a chọrọ usoro mgbochi ọkụ na mgbawa kwesịrị ekwesị mgbe ị na-echekwa ma na-ejikwa nitrophenylhydrazine. Na mgbakwunye, nitrophenylhydrazine na-agbakasịkwa ahụ ma nwee mmetụta na-emebi emebi na anya, akpụkpọ na akụkụ iku ume. Ọ dị mkpa iyi akụrụngwa nchedo onwe onye kwesịrị ekwesị n'oge arụ ọrụ.
