6-Chloro-2-methyl-3-nitropyridine (CAS# 22280-60-0)
| Amakhodi Engozi | R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. I-R22 – Iyingozi uma igwinywe |
| Incazelo Yokuphepha | S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. |
| Ikhodi ye-HS | 29333990 |
| Inothi Lengozi | Kuyingozi |
| I-Hazard Class | I-IRRITANT |
Isingeniso
I-2-Chloro-6-methyl-5-nitropyridine iyinhlanganisela evamile yezinto eziphilayo,
Ikhwalithi:
- Ukubukeka: I-2-chloro-6-methyl-5-nitropyridine iyi-crystalline eqinile engenambala noma ephuzi.
- I-Solubility: Incibilika kalula kuzincibilikisi zemvelo ezifana ne-ethanol, i-dimethylformamide ne-chloroform.
Sebenzisa:
- Amadayi: Le nhlanganisela ingasetshenziswa ukuhlanganisa odayi abathile bezimboni, njengokuthi isakhiwo sinendawo yokumunca ukukhanya kwe-UV, futhi sisetshenziswa kabanzi embonini ye-pigment nodayi.
Indlela:
I-2-Chloro-6-methyl-5-nitropyridine ingatholakala nge-chlorination kanye ne-nitrification ye-pyridine. Indlela eqondile yokulungiselela kungaba ukusebenzisa i-nitric acid ne-sulfuric acid ukuze kusabele ukuthola i-nitrite acid, kusabela i-nitrite ne-nitrate yethusi ukuze kwakhiwe i-nitrate yethusi, bese usebenzisa ama-electrophilic methylation reagents (njenge-methyl halogen) ukuze asabele nge-nitrate yethusi ukuze uthole umkhiqizo okuhlosiwe.
Ulwazi Lokuphepha:
I-2-Chloro-6-methyl-5-nitropyridine iyinhlanganisela enobuthi ecasulayo futhi eyingozi. Lapho usebenzisa futhi uphatha, kudingeka izinyathelo zokuphepha ezifanele njengokugqoka izingubo zamehlo ezivikelayo, amagilavu nezingubo zokuzivikela. Gwema ukuhogela umhwamuko noma uthuli lwawo, futhi gwema ukuthinta isikhumba namehlo. Uma usebenzisa le nhlanganisela, ukunakekelwa kufanele kuthathwe ekuzinzeni kwayo futhi ugweme ukuthintana namanye amakhemikhali angahambelani. Lapho uyigcina, kufanele igcinwe esitsheni esingangeni moya, kude nokushisa kanye nama-oxidants.
