Mawu Oyamba
2,3,5-Trifluoropyridine ndi organic pawiri ndi mankhwala chilinganizo C5H2F3N. Zotsatirazi ndizofotokozera za chikhalidwe chake, kugwiritsa ntchito, kukonzekera ndi chitetezo:
Chilengedwe:
2,3,5-Trifluoropyridine ndi madzi opanda mtundu okhala ndi fungo loipa. Lili ndi kachulukidwe ka 1.42 g/mL, kuwira kwa 90-91°C, ndi malo osungunuka -47°C. Ili ndi mphamvu ya hydrophobicity ndipo imakhala yovuta kusungunuka m'madzi, koma imatha kusungunuka muzosungunulira zamagulu monga ethanol, acetone ndi xylene.
Gwiritsani ntchito:
2,3,5-Trifluoropyridine imagwiritsidwa ntchito kwambiri popanga organic synthesis. Monga ogwira fluorination reagent, angagwiritsidwe ntchito fluorination zimachitikira, ndipo nthawi zambiri ntchito anachita poyambitsa maatomu fluorine. Komanso, angagwiritsidwe ntchito ngati wapakatikati kwa synthesis mankhwala, mankhwala ndi zina organic mankhwala.
Njira Yokonzekera:
2,3,5-Trifluoropyridine ili ndi njira zambiri zokonzekera, imodzi mwazomwe zimagwiritsidwa ntchito kupeza pochita 2,3, 5-trichloropyridine ndi hydrofluoric acid. Pa anachita, 2,3, 5-trichloropyridine ndi anachita ndi hydrofluoric asidi mu zosungunulira abwino, ndi mmene kutentha ndi pH mtengo amalamulidwa kuti potsiriza kupeza 2,3,5-Trifluoropyridine.
Zambiri Zachitetezo:
Samalani njira zachitetezo mukamagwira 2,3,5-Trifluoropyridine. Ndi fungo lonunkhira bwino lomwe lingayambitse khungu, maso ndi kupuma. Choncho, pewani kukhudzana mwachindunji ndi khungu ndi maso pamene mukugwiritsa ntchito, ndipo onetsetsani kuti mukugwira ntchito pamalo abwino mpweya wabwino. Pogwira ndi kusunga, ndikofunikira kutenga njira zodzitetezera ndikupewa kukhudzana ndi ma oxidizing ndi ma acid amphamvu kuti mupewe zoopsa.
Kuphatikiza apo, pakugwiritsa ntchito mankhwala aliwonse, chonde tsatirani njira zolondola zogwirira ntchito ndi malamulo oyenera, ndipo funsani malangizo a akatswiri pakafunika kutero.
