Selelekela
2,3,5-Trifluoropyridine ke motsoako oa manyolo o nang le motsoako oa lik'hemik'hale C5H2F3N. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:
Tlhaho:
2,3,5-Trifluoropyridine ke mokelikeli o se nang 'mala o monko o monate. E na le boima ba 1.42 g/mL, ntlha e belang ea 90-91°C, le ntlha ea ho qhibiliha ke -47°C. E na le hydrophobicity e matla 'me e thata ho qhibiliha ka metsing, empa e ka qhibiliha ka li-solvents tse tloaelehileng tse kang ethanol, acetone le xylene.
Sebelisa:
2,3,5-Trifluoropyridine e sebelisoa haholo-holo tšimong ea tlhaho ea tlhaho. E le sesebelisoa se sebetsang sa fluorination, se ka sebelisoa ho karabelo ea fluorination, 'me hangata se sebelisoa karabelong ea ho hlahisa liathomo tsa fluorine. Ho phaella moo, e ka boela ea sebelisoa e le setsi sa ho kopanya lithethefatsi, chefo e bolaeang likokoanyana le metsoako e meng ea manyolo.
Mokhoa oa ho itokisa:
2,3,5-Trifluoropyridine e na le mekhoa e mengata ea ho itokisa, e 'ngoe ea eona e atisang ho sebelisoa ho e fumana ka ho arabela 2,3, 5-trichloropyridine le hydrofluoric acid. Nakong ea karabelo, 2,3, 5-trichloropyridine e sebetsanoa le hydrofluoric acid ka har'a motsoako o loketseng, 'me mocheso oa karabelo le pH bohlokoa li laoloa ho qetella li fumane 2,3,5-Trifluoropyridine.
Lintlha tsa Tšireletseho:
Ela hloko mehato ea tšireletso ha u tšoara 2,3,5-Trifluoropyridine. Ke motsoako o monko o monate o ka bakang ho teneha letlalong, mahlo le tsamaiso ea ho hema. Ka hona, qoba ho kopana ka ho toba le letlalo le mahlo ha u sebelisa, 'me u etse bonnete ba hore u sebetsa sebakeng se nang le moea o motle. Nakong ea ho ts'oaroa le ho boloka, hoa hlokahala ho nka mehato e nepahetseng ea ts'ireletso le ho qoba ho kopana le li-oxidizing agents le li-acid tse matla ho thibela liketso tse kotsi.
Ho feta moo, bakeng sa tšebeliso ea lik'hemik'hale life kapa life, ka kopo latela mekhoa e nepahetseng ea ts'ebetso le melaoana e amehang, 'me u buisane le tataiso ea litsebi ha ho hlokahala.
