2-Amino-5-nitrophenol(CAS#121-88-0)
| Izimpawu Eziyingozi | I-Xn - Iyingozi |
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. I-R68 – Ingozi engaba khona yemiphumela engenakuhlehliswa |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) |
Isingeniso
I-5-Nitro-2-aminophenol, eyaziwa nangokuthi i-5-nitro-m-aminophenol, iyinhlanganisela yezinto eziphilayo. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: I-5-nitro-2-aminophenol iyikristalu ephuzi ekhanyayo noma impushana.
-Ukunyibilika: Cishe ayincibiliki emanzini, kodwa ingancibilika kuzincibilikisi zemvelo ezifana notshwala nama-ether.
-Indawo yokuncibilika: Indawo yayo yokuncibilika icishe ibe ngu-167-172°C.
-Izici ze-Chemical: Kuyinto ene-asidi ebuthakathaka engasabela nge-alkali ukuze ikhiqize usawoti. Ingase futhi ibhekane nokusabela kwe-electrophilic substitution, njengokusabela kwe-nitration.
Sebenzisa:
-5-Nitro-2-aminophenol isetshenziswa ngokujwayelekile njengendawo yokwenziwa kodayi namadayi.
-Ingasetshenziswa futhi ukwenza izinto eziphilayo ezifana nezibulala-zinambuzane, izidakamizwa kanye nezithasiselo zenjoloba.
Indlela:
-5-nitro-2-aminophenol ngokuvamile ilungiselelwe ukusabela kwe-condensation ye-m-nitrophenol ne-aminophenol. Indlela ethile yokulungiselela ingase yehluke kuye ngezimo ezithile zokuhlola.
Ulwazi Lokuphepha:
-5-Nitro-2-aminophenol iyinhlanganisela yezinto eziphilayo ezinobuthi obuthile futhi ingase ibangele ukulimala emzimbeni womuntu.
-Ukuxhumana noma ukuhogela kwalesi sithako kungase kubangele ukucasuka kwamehlo nesikhumba futhi kungase kubangele ukucasuka kokuphefumula.
-Qaphela izinqubo zokuphepha ezifanele ngesikhathi sokusebenza futhi usebenzise izinto zokuzivikela ezifanele, njengamagilavu, izibuko nezingubo zokuzivikela.
-Uma uthintana noma uhogela umoya, shayela indawo ethintekile ngokushesha ngamanzi futhi ufune usizo lwezempilo.
