Isingeniso

I-2-fluoro-3-methylpyrridine (2-fluoro-3-methylpyrridine) iyinhlanganisela yemvelo enefomula yamakhemikhali ethi C6H6FN.

 

Imvelo:

I-2-fluoro-3-methylpyridine iwuketshezi olungenambala olunephunga elimnandi. Iyaguquguquka ezingeni lokushisa lasekamelweni futhi incibilika kuzincibilikisi zemvelo njenge-ethanol ne-ether. Inephuzu lokuncibilika elingu -31°C kanye nephuzu lokubila elingu-129°C.

 

Sebenzisa:

I-2-fluoro-3-methylpyridine inohlu olubanzi lwezinhlelo zokusebenza ku-organic synthesis. Iyingxenye yezinhlanganisela eziningi ezibalulekile futhi ingasetshenziswa ukulungisa izidakamizwa ezihlukahlukene, izibulala-zinambuzane kanye nezinto zokusebenza.

 

Indlela:

Ukulungiswa kwe-2-fluoro-3-methylpyriridine ngokuvamile kutholakala ngokuphendula i-pyridine ngegesi ye-fluorine. Esinyathelweni esithile, igesi ye-pyridine ne-fluorine isabela nge-catalyst ngaphansi kwezimo ezifanele zokusabela ukuze zithole i-2-fluoro-3-methylpyriridine.

 

Ulwazi Lokuphepha:

I-2-fluoro-3-methylpyridine iyacasula futhi ingabangela ukucasuka emehlweni, isikhumba, kanye nesistimu yokuphefumula. Ngesikhathi sokusetshenziswa, ukunakekelwa kufanele kuthathwe ukuze ugweme ukuthintana nesikhumba namehlo, futhi ugcine izimo ezinhle zokungenisa umoya. Ngesikhathi sokuphatha nokugcinwa, izinqubo ezifanele zokusebenza eziphephile kufanele zilandelwe ukuze kugwenywe ukuchayeka emlilweni kanye nezinga lokushisa eliphezulu. Uma uthintana ngephutha, hlambulula ngokushesha ngamanzi amaningi futhi ufune usizo lwezokwelapha.
