Sumo pfupi
3-Bromo-5-nitro-2-hydroxypyridine musanganiswa weorganic unowanzo kupfupikiswa seBNHO.
Properties: Chitarisiko:
-Kuonekwa: BNHO ikiristiri yero kana kuti crystalline poda.
- Solubility: inonyungudika zvishoma mumvura, inonyungudika mudoro, ether uye mamwe organic solvents.
Zvishandiso:
- Pesticide raw material: BNHO inogona kushandiswa seyakagadzirwa kugadzirwa kweimwe mishonga yezvipembenene.
Kugadzirira nzira:
Pane nzira mbiri dzekugadzirira dzinozivikanwa: imwe iri kuburikidza nealkylation reaction yebromobenzene uye 2-hydroxypyridine kuti iwane 3-bromo-2-hydroxypyridine, uye wozoita nenitric acid kuti uwane 3-bromo-5-nitro-2-hydroxypyridine. Imwe iri kuburikidza nekuita kwe2-bromo-3-methylpyridine ne nitric acid kuwana 3-bromo-5-nitro-2-hydroxypyridine.
Zvekuchengetedza
- BNHO inhengo ye organohalogen ine chepfu uye inogumbura uye matanho ekudzivirira anofanira kuonekwa.
- Dzivisa kusangana neganda, maziso uye mucous membranes; kana masangana, geza nekukasika nemvura yakawanda.
- Pfeka midziyo yekudzivirira yakakodzera, senge magirovhosi emurabhoritari uye magirazi ekuchengetedza, paunenge uchiishandisa nekuigadzira.
- Dzivisa kufemesa mhute kana guruva uye shanda munzvimbo ine mhepo inofefetera.
-Inofanirwa kuchengetwa munzvimbo yakaoma, inotonhorera uye inofefetera kure nenzvimbo dzekupisa kana oxidising agents.
