Mawu Oyamba
5-(trifluoromethyl)pyridine-2-carbonitrile(5-(trifluoromethyl)pyridine-2-carbonitrile) ndi organic pawiri ndi mankhwala chilinganizo C7H2F3N.
Chilengedwe:
5-(trifluoromethyl)pyridine-2-carbonitrile ndi madzi opanda mtundu okhala ndi fungo lapadera. Ndi kachulukidwe pafupifupi 1.34 g/mL ndi kuwira 162-165 ° C.
Gwiritsani ntchito:
5- (trifluoromethyl) pyridine-2-carbonitrile ndi yofunika kwambiri organic synthesis wapakatikati, yomwe imagwiritsidwa ntchito kwambiri mu zamankhwala, mankhwala ophera tizilombo, sayansi yazinthu ndi zina. Itha kugwiritsidwa ntchito popanga mankhwala oletsa khansa, mankhwala ophera tizilombo ndi zinthu zina zamagetsi zamagetsi.
Njira Yokonzekera:
5-(trifluoromethyl)pyridine-2-carbonitrile imakonzedwa ndi njira zosiyanasiyana, makamaka kuphatikiza izi:
1. ndi 2-cyano-5-bromomethylpyridine ndi trifluoromethyl bromide reaction.
2. 2-Cyano-5-methylpyridine imakhudzidwa ndi trifluoromethyl bromide pamaso pa sodium chloride pa kutentha kwakukulu.
Zambiri Zachitetezo:
Chifukwa 5-(trifluoromethyl)pyridine-2-carbonitrile imakhala ndi zotsatira zokhumudwitsa m'maso, pakhungu ndi m'mapapo, chisamaliro chiyenera kutengedwa kuti musakhudzidwe mukamagwiritsa ntchito. Mukakumana ndi mankhwalawa, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupempha thandizo lachipatala. Kuonjezera apo, ndi madzi oyaka moto ndipo ayenera kusungidwa kutali ndi magwero a moto ndi malo otentha kwambiri, ndipo samalani ndi kuteteza moto ndi kuphulika. Mukamagwiritsa ntchito ndikusunga, chonde tsatirani njira zoyenera zotetezera.
