2-Amino-3-bromo-5-nitropyridine (CAS# 15862-31-4)
Ubungozi Nokuphepha
| Izimpawu Eziyingozi | Xi - Irritant |
| Amakhodi Engozi | 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | I-S37/39 – Gqoka amagilavu afanelekile kanye nokuvikela iso/ubuso S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36 – Gqoka izingubo ezifanele zokuzivikela. |
| Ikhodi ye-HS | 29333990 |
| I-Hazard Class | I-IRRITANT |
15862-31-4 - Isingeniso
Ezinye izici zalesi sakhiwo zimi kanje:
1. Ukubukeka: okuphuzi okuphaphathekile kuya ku-orange-yellow crystalline powder.
2. I-Melting Point: izinga layo lokuncibilika lingama-80-86 degrees Celsius.
3. Ukuncibilika: Ingancibilika kuzincibilikisi eziningi eziphilayo, njenge-ethanol, i-methanol, njll. Ukuncibilika kwayo emanzini kuphansi kakhulu.
Inokusebenza okuthile ku-organic synthesis. Ingasetshenziswa njengenhlanganisela yezinto ezingavuthiwe ku-organic synthesis, iqhaza ekuphenduleni kwamakhemikhali okuhlukahlukene, futhi ihlanganise izinhlanganisela ezihlukene ze-organic noma izixhumanisi.
Indlela yokulungisa i-calcium ivame ukuqhutshwa yi-nucleophilic substitution reaction. Indlela eyodwa evamile yokulungiselela iwukusabela i-3-bromo-2-nitropyridine ngenhlanganisela yama-amino ukuze kwakhiwe umkhiqizo ofunekayo.
Mayelana nolwazi lokuphepha, kuyinhlanganisela yezinto eziphilayo ezingase zibe nobuthi obuthile nokucasuka. Izinyathelo zokuphepha ezifana namagilavu amelana namakhemikhali, izibuko kanye nokukhipha umoya kuyadingeka ngesikhathi sokuphatha nokusebenzisa. Ngesikhathi esifanayo, kufanele igcinwe esitsheni esivaliwe, kude nemithombo yomlilo nezinye izinto ezivuthayo. Uma uthintana ngenhloso noma ukumunca, funa usizo lwezokwelapha ngokushesha. Hlala ulandela izinqubo zokuphepha ezifanele, njengokulahlwa okufanele kwensalela noma imfucuza.
