Isingeniso esifushane
I-3-Bromo-5-nitro-2-hydroxypyridine iyinhlanganisela yemvelo evame ukufushaniswa njenge-BNHO.
Izakhiwo: Ukubukeka:
- Ukubukeka: I-BNHO iyikristalu ephuzi ekhanyayo noma i-crystalline powder.
- Ukunyibilika: kuncibilika kancane emanzini, kuncibilika otshwaleni, ether nakwezinye izinyibilikisi zemvelo.
Isebenzisa:
- I-pesticide eluhlaza: I-BNHO ingasetshenziswa njengezinto ezingavuthiwe zokuhlanganiswa kwezibulala-zinambuzane ezithile.
Indlela yokulungiselela:
Kunezindlela ezimbili ezijwayelekile zokulungiselela: eyodwa iwukusabela kwe-alkylation kwe-bromobenzene kanye ne-2-hydroxypyridine ukuze uthole i-3-bromo-2-hydroxypyridine, bese isabela nge-nitric acid ukuze uthole i-3-bromo-5-nitro-2-hydroxypyridine. Okunye ukusabela kwe-2-bromo-3-methylpyridine nge-nitric acid ukuthola i-3-bromo-5-nitro-2-hydroxypyridine.
Ulwazi Lokuphepha:
- I-BNHO iyinhlanganisela ye-organohalogen enobuthi futhi ecasulayo futhi izinyathelo zokuzivikela kufanele zibhekwe.
- Gwema ukuthinta isikhumba, amehlo kanye nolwelwesi lwamafinyila; uma uthinta, shayela ngokushesha ngamanzi amaningi.
- Gqoka izinto zokuzivikela ezifanele, njengamagilavu aselabhorethri kanye nezibuko zokuphepha, lapho uzisebenzisa futhi uzilungiselela.
- Gwema ukuhogela umhwamuko noma uthuli futhi usebenze endaweni engenawo umoya.
- Kufanele igcinwe endaweni eyomile, epholile futhi engenawo umoya kude nemithombo yokuthungela noma izinto ezikhipha i-oxidizing.
