Omaka bomkhiqizo

Amakhodi Engozi I-R22 – Iyingozi uma igwinywe
R37/38 – Ukucasula uhlelo lokuphefumula kanye nesikhumba.
R41 – Ingozi yokulimala okubi emehlweni
R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.

Isingeniso

I-4-Bromo-2-chloropyridine, eyaziwa nangokuthi i-bromochloropyridine, iyinhlanganisela ye-halopyridine. Okulandelayo yisingeniso esifushane sezakhiwo, ukusetshenziswa, izindlela zokulungisa, kanye nolwazi lokuphepha kwenhlanganisela:

 

Ikhwalithi:

- Ukubukeka: Amakristalu aphuzi angenambala noma akhanyayo

 

Sebenzisa:

I-4-Bromo-2-chloropyridine iyi-reagent evame ukusetshenziswa ekuhlanganiseni kwe-organic.

- Ingasetshenziswa njengempahla eluhlaza yezibulala-zinambuzane nezibulala-zinambuzane

 

Indlela:

I-4-Bromo-2-chloropyridine ingalungiswa ngu:

I-2-chloropyridine isabela nge-bromine ukuthola umkhiqizo

 

Ulwazi Lokuphepha:

- I-4-Bromo-2-chloropyridine iyacasula futhi iyingozi

- Gwema ukuthinta isikhumba, amehlo, kanye nomgudu wokuphefumula

- Gqoka amagilavu ​​okuvikela afanele, amehlo, nezinto zokuphefumula lapho usebenzisa

- Sebenza endaweni engenawo umoya

- Gcina kude nokukhanya, okomile, ukungena komoya, futhi kude nezinto ezivuthayo kanye nama-oxidants

Hlala uphephile uma usebenzisa noma uphatha amakhemikhali.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
