Ubungozi Nokuphepha

Amakhodi Engozi I-R22 – Iyingozi uma igwinywe
R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba.
R41 – Ingozi yokulimala okubi emehlweni
Incazelo Yokuphepha 26 - Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.

5-BROMO-2-HYDROXY-4-METHYLPYRIDINE (CAS# 164513-38-6) Isingeniso

Kuyinhlanganisela yemvelo enefomula yamakhemikhali ethi C8H8BrNO. Inezici ezilandelayo:1. Ukubukeka: Iqinile engenambala noma ephuzi ngokukhanyayo.2. Ukunyibilika: Kungancibilika kancane emanzini futhi kuncibilika kalula kuzincibilikisi zemvelo njenge-ethanol ne-dimethyl sulfoxide.

3. Inani le-PH: Ayithathi hlangothi noma ine-asidi kancane kusisombululo esinamanzi.

4. Ukusebenza kabusha: Kuyi-reagent ye-electrophilic engabamba iqhaza ekuphenduleni okuningi kwezinto eziphilayo, njengokusabela kokushintshwa kwe-electrophilic, ukusabela kwe-oxidation, njll.

5. Ukuzinza: Kuzinzile ekamelweni lokushisa, kodwa kungase kubole ngaphansi kwesenzo sokushisa okuphezulu, i-oxidant noma i-asidi eqinile.

Inezinhlobonhlobo zezicelo elabhorethri nasembonini, kufaka phakathi lokhu okulandelayo:

1. Njenge-reagent yamakhemikhali: ingasetshenziswa njenge-reagent ye-electrophilic, i-Catalyst noma i-ejenti yokunciphisa ku-organic synthesis.

2. Njengesilondolozi: Ngenxa yezakhiwo zayo zokulwa ne-antibacterial, ingasetshenziswa ekulungiseleleni izivimbelakuvunda, ezivame ukusetshenziselwa ukuvikela izinkuni, izindwangu, njll.

3. Inkundla yezokwelapha: ingasetshenziswa ekuhlanganiseni izidakamizwa noma njengezilamuli zemithi ethile.

Indlela evamile yokulungisa usawoti ngokusabela i-2-picoline nge-bromine. Izinyathelo eziqondile zingabhekisela endleleni elandelayo: Okokuqala, ngaphansi kwezimo ezifanele zokusabela, i-2-methylpyridine isabela nge-bromine ukuze ithole i-5-bromo-2-methylpyridine. Khona-ke, ngaphansi kwezimo ze-alkaline, i-5-bromo -2-methyl pyridine iphathwa nge-sodium hydroxide ukuze itholakale.

Mayelana nolwazi lokuphepha, okulandelayo kufanele kuqashelwe uma usebenzisa noma uphatha insimbi:

1. Gwema ukuthintana ngqo nesikhumba, amehlo, isistimu yokuphefumula, njll. Gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko namamaski.

2. Gcina indawo enomoya omuhle ngesikhathi sokuyisebenzisa futhi ugweme ukuhogela umhwamuko wawo.

3. Isitoreji kufanele sifakwe esitsheni esivaliwe, gwema ukukhanya kwelanga nokushisa okuphezulu.

4. Uma ugwinywe ngephutha noma uthintana nesikhumba, geza ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha kusenesikhathi.

5. Ekusetshenzisweni noma ekuchithweni kwenkomponi, kufanele kuhambisane nemithetho yendawo kanye nemithethonqubo kanye nezinqubo zokuphepha.
