Intangiriro
2,3,5-Trifluoropyridine ni ifumbire mvaruganda hamwe na formula ya chimique C5H2F3N. Ibikurikira nubusobanuro bwimiterere yabyo, imikoreshereze, imyiteguro namakuru yumutekano:
Kamere:
2,3,5-Trifluoropyridine ni amazi atagira ibara afite impumuro nziza. Ifite ubucucike bwa 1,42 g / mL, ahantu hatetse 90-91 ° C, no gushonga -47 ° C. Ifite hydrophobicity ikomeye kandi biragoye gushonga mumazi, ariko irashobora gushonga mumashanyarazi asanzwe nka Ethanol, acetone na xylene.
Koresha:
2,3,5-Trifluoropyridine ikoreshwa cyane mubijyanye na synthesis organique. Nka reagent nziza ya fluor, irashobora gukoreshwa mubitekerezo bya fluor, kandi ikoreshwa kenshi mubitekerezo byo kwinjiza atome ya fluor. Byongeye kandi, irashobora kandi gukoreshwa nkigihe cyo guhuza imiti, imiti yica udukoko hamwe n’ibindi binyabuzima.
Uburyo bwo Gutegura:
2,3,5-Trifluoropyridine ifite uburyo bwinshi bwo gutegura, bumwe muribwo bukoreshwa muburyo bwo kubona hakoreshejwe 2,3, 5-trichloropyridine hamwe na aside hydrofluoric. Mugihe cyo kubyitwaramo, 2,3, 5-trichloropyridine ikorwa na acide hydrofluoric mumashanyarazi ikwiye, kandi ubushyuhe bwibisubizo hamwe nagaciro ka pH bigenzurwa kugirango amaherezo abone 2,3,5-Trifluoropyridine.
Amakuru yumutekano:
Witondere ingamba z'umutekano mugihe ukoresha 2,3,5-Trifluoropyridine. Nibintu bihumura neza bishobora gutera uburakari kuruhu, amaso hamwe nubuhumekero. Noneho, irinde guhura nuruhu n'amaso mugihe ukoresheje, kandi urebe neza ko ukorera ahantu hafite umwuka mwiza. Mugihe cyo gutunganya no kubika, birakenewe gufata ingamba zikwiye zo kurinda no kwirinda guhura na okiside hamwe na acide zikomeye kugirango wirinde ingaruka mbi.
Byongeye kandi, kugirango ukoreshe imiti iyo ari yo yose, nyamuneka ukurikize uburyo bukwiye bwo gukora n'amabwiriza abigenga, kandi ubaze ubuyobozi bw'umwuga igihe bibaye ngombwa.
