Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile.
Incazelo Yokuphepha S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.
S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36 – Gqoka izingubo ezifanele zokuzivikela.
Ikhodi ye-HS 29349990

 

Isingeniso

I-2-Chloro-3-nitro-6-methylpyridine iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: I-2-chloro-3-nitro-6-methylpyridine iyikristale ephuzi eqinile.

- Ukunyibilika: Kuncibilika kalula kuzincibilikisi zemvelo futhi kuncibilika kancane emanzini.

 

Sebenzisa:

- I-2-Chloro-3-nitro-6-methylpyridine ijwayele ukusetshenziswa njengesibulala-zinambuzane ukulawula ukhula ezitshalweni ezifana nerayisi nokolweni.

- Inemisebenzi yokubulala izinambuzane, ukutshala, futhi inokukhethwa okuphezulu kokhula oluthile.

 

Indlela:

- I-2-Chloro-3-nitro-6-methylpyridine ingatholwa ngokuqala ngokusabela i-2,6-dimethylpyridine nge-Cl2-NaNO2 ukuze kutholwe okuphuma ku-2-chloro-3-nitro-6-methylpyridine, bese kuba nokusabela kokunciphisa ukuthola umkhiqizo ohlosiwe.

 

Ulwazi Lokuphepha:

- I-2-chloro-3-nitro-6-methylpyridine iyinhlanganisela enobuthi engaba yingozi kubantu uma ithintwa, ihogelwa, noma imunywe ngokweqile.

- Izinto zokuzivikela ezinjengamagilavu ​​okuzivikela, izibuko, namamaski kufanele zigqokwe lapho kusetshenziswa noma kusingathwa inhlanganisela, futhi kufanele kuqinisekiswe ukungena komoya okwanele.

- Gwema ukuthinta isikhumba, amehlo, ulwelwesi lwamafinyila, njll., hlambulula ngokushesha ngamanzi amaningi futhi ufune ukwelashwa.

- Ngesikhathi sokugcinwa kanye nokuthuthwa kwenhlanganisela, kufanele igcinwe kude nokuvutha kanye nama-oxidants, futhi igcinwe endaweni evaliwe, eyomile nepholile.

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