Isingeniso

I-5-Fluoro-2-hydroxypyridine iyinhlanganisela yemvelo enefomula yamakhemikhali ethi C5H4FN2O. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:

 

Imvelo:

-5-Fluoro-2-hydroxyypyridine iqinile engenambala ukuya kokuphuzi kancane.

-Isisindo samangqamuzana singu-128.10g/mol.

-Inephunga elimnandi.

-Incibilika emanzini ekamelweni lokushisa.

 

Sebenzisa:

-5-Fluoro-2-hydroxyypyridine ingasetshenziswa njengento ebalulekile ephakathi ekuhlanganiseni kwezinto eziphilayo.

-Ivame ukusetshenziswa njengento eyinhloko yemithi yokwenziwa embonini yezemithi.

-Ingasetshenziswa futhi ekukhiqizeni odayi, ama-pigments namanye amakhemikhali.

 

Indlela Yokulungiselela:

-Indlela evame ukusetshenziswa yokulungiselela iwukwenza i-5-Fluoro-2-hydroxypyridine ngokusabela i-2-amino-5-fluoropyridine kanye ne-oxidizing agent ngaphansi kwezimo ezifanele.

 

Ulwazi Lokuphepha:

- I-5-Fluoro-2-hydroxypyridine kufanele igcinwe endaweni eyomile, enomoya omuhle.

-Gqoka izinto zokuzivikela ezifanele njengamagilavu, izibuko nezingubo zokuzivikela ngesikhathi sokuphatha nokusebenzisa.

-Gwema ukuhogela uthuli noma igesi yayo, futhi gwema ukuthintana nesikhumba namehlo.

-Uma ingena ngephutha emehlweni noma esikhumbeni, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.

-Sicela uyigcine kahle futhi ufunde ishidi layo ledatha yokuphepha ngokucophelela ngaphambi kokuliphatha noma ukuliphatha.

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