Okwu mmalite
2,3,5-Trifluoropyridine bụ ngwakọta organic na usoro kemịkalụ C5H2F3N. Nke a bụ nkọwa nke ọdịdị ya, ojiji ya, nkwadebe na ozi nchekwa ya:
Ọdịdị:
2,3,5-Trifluoropyridine bụ mmiri mmiri na-enweghị agba nke nwere isi ísì. O nwere njupụta nke 1.42 g/mL, ebe esi esi 90-91 Celsius C, na ebe agbaze -47 Celsius. O nwere hydrophobicity siri ike ma sie ike igbari na mmiri, mana enwere ike ịgbaze ya na ihe mgbaze organic nkịtị dị ka ethanol, acetone na xylene.
Jiri:
2,3,5-Trifluoropyridine bụ nke a na-ejikarị eme ihe n'ọhịa nke njikọ organic. Dị ka ihe dị irè fluorination reagent, enwere ike iji ya na mmeghachi omume fluorination, a na-ejikarị ya eme ihe na mmeghachi omume nke iwebata atom fluorine. Tụkwasị na nke ahụ, a pụkwara iji ya mee ihe dị ka onye na-ahụ maka njikọ nke ọgwụ, pesticides na ndị ọzọ organic ogige.
Ụzọ nkwadebe:
2,3,5-Trifluoropyridine nwere ọtụtụ ụzọ nkwadebe, otu n'ime ha na-ejikarị nweta site na-emeghachi omume 2,3, 5-trichloropyridine na hydrofluoric acid. N'oge mmeghachi omume ahụ, 2,3, 5-trichloropyridine na-emeghachi omume na hydrofluoric acid na ihe mgbaze kwesịrị ekwesị, a na-achịkwa okpomọkụ mmeghachi omume na uru pH iji nweta 2,3,5-Trifluoropyridine n'ikpeazụ.
Ozi nchekwa:
Lezienụ anya na usoro nchekwa mgbe ị na-eji 2,3,5-Trifluoropyridine. Ọ bụ ihe na-esi ísì ụtọ nke nwere ike ịkpasu akpụkpọ ahụ, anya na akụkụ iku ume. Ya mere, zere kọntaktị ozugbo na akpụkpọ ahụ na anya mgbe ị na-eji ya, ma hụ na ị na-arụ ọrụ na ebe ikuku na-ekpo ọkụ. N'oge njikwa na nchekwa, ọ dị mkpa ịme ihe nchebe kwesịrị ekwesị ma zere ịkpọtụrụ ndị na-emepụta ihe na-emepụta ihe na acid siri ike iji gbochie mmeghachi omume dị ize ndụ.
Na mgbakwunye, maka iji kemịkalụ ọ bụla, biko soro usoro arụ ọrụ ziri ezi na ụkpụrụ dị mkpa, ma gakwuru ntuziaka ọkachamara mgbe ọ dị mkpa.
