Intshayelelo emfutshane
I-3-Bromo-5-nitro-2-hydroxypyridine i-organic compound idla ngokufinyezwa njenge-BNHO.
Iinkcazelo ngeempawu: Imbonakalo:
- Imbonakalo: I-BNHO yikristale etyheli ekhanyayo okanye umgubo wekristale.
- Ukunyibilika: kunyibilika kancinane emanzini, kunyibilika etywaleni, kwi-ether nakwezinye izinyibilikisi eziphilayo.
Usebenzisa:
- I-Pesticide ekrwada: I-BNHO ingasetyenziswa njengezinto ezikrwada zokudityaniswa kwezibulali-zinambuzane ezithile.
Indlela yokulungiselela:
Kukho iindlela ezimbini eziqhelekileyo zokulungiselela: enye nge-alkylation reaction ye-bromobenzene kunye ne-2-hydroxypyridine ukufumana i-3-bromo-2-hydroxypyridine, kwaye emva koko iphendule nge-nitric acid ukuze ifumane i-3-bromo-5-nitro-2-hydroxypyridine. Enye i-reaction ye-2-bromo-3-methylpyridine kunye ne-nitric acid ukufumana i-3-bromo-5-nitro-2-hydroxypyridine.
Ulwazi ngoKhuseleko:
- I-BNHO yi-organohalogen compound enetyhefu kwaye iyacaphukisa kwaye amanyathelo okukhusela kufuneka abonwe.
- Gwema ukudibana nolusu, amehlo kunye ne-mucous membranes; xa udibana, gungxula ngokukhawuleza ngamanzi amaninzi.
- Nxiba izixhobo ezifanelekileyo zokuzikhusela, ezinjengeeglavu zaselabhoratri kunye neeglasi zokhuseleko, xa uzisebenzisa kwaye uzilungiselela.
• Kuphephe ukuphefumla umphunga okanye uthuli lwayo kwaye usebenze kwindawo engena umoya.
- Kufuneka igcinwe kwindawo eyomileyo, epholileyo nengena umoya kude nemithombo yokutshisa okanye i-oxidizing agents.
