5-BROMO-2-HYDROXY-4-METHYLPYRIDINE (CAS# 164513-38-6) Nhanganyaya
3. PH kukosha: Haina kwayakarerekera kana kuti iine acidic zvishoma mumushonga une aqueous.
4. Reactivity: I electrophilic reagent inogona kutora chikamu mune zvakawanda organic reactions, senge electrophilic substitution reactions, oxidation reactions, nezvimwe.
5. Kugadzikana: Yakagadzikana pakupisa kwekamuri, asi inogona kuora pasi pekuita kwekushisa kwepamusoro, oxidant kana yakasimba acid.
Iine huwandu hwakawanda hwekushandisa murabhoritari uye indasitiri, kusanganisira zvinotevera:
1. Semakemikari reagent: inogona kushandiswa se electrophilic reagent, Catalyst kana kuderedza agent mu organic synthesis.
2. Sekuchengetedza: Pamusana pemishonga inorwisa mabhakitiriya, inogona kushandiswa pakugadzirira kwekuchengetedza, inowanzoshandiswa kuchengetedza huni, machira, nezvimwewo.
3. Munda wemishonga: inogona kushandiswa mukugadzirwa kwemishonga kana sepakati pemamwe mishonga.
Nzira yakajairika yekugadzira munyu ndeyekuita 2-picoline nebromine. Matanho chaiwo anogona kureva nzira inotevera: Kutanga, pasi pemamiriro akakodzera ekuita, 2-methylpyridine inobatwa nebromine kuti iwane 5-bromo-2-methylpyridine. Zvadaro, pasi pemamiriro e-alkaline, 5-bromo -2-methyl pyridine inobatwa ne sodium hydroxide kuti iwane.
Nezve ruzivo rwekuchengetedza, zvinotevera zvinofanirwa kucherechedzwa kana uchishandisa kana kubata simbi:
1. Dzivisa kusangana zvakananga neganda, maziso, hurongwa hwekufema, nezvimwe. Pfeka midziyo yekuzvidzivirira nayo yakakodzera semagirovhosi, magirazi uye masks.
2. Chengetedza nzvimbo ine mhepo yakanaka panguva yekushandiswa uye usapinda mumhepo yaro.
3. Kuchengetedza kunofanira kuiswa mumudziyo wakavharwa, kudzivisa zuva rakananga uye kupisa kwakanyanya.
4. Kana akamedzwa netsaona kana kuti ganda rakabatana, simbura pakarepo nemvura yakawanda uye tsvaka rubatsiro rwechiremba munguva.
5. Mukushandiswa kana kuraswa kwekomboni, inofanirwa kutevedzera mitemo yemuno nemirairo uye nzira dzekuchengetedza.
