Mawu Oyamba
3-(trifluoromethyl)pyridine, yomwe imadziwikanso kuti 1-(trifluoromethyl)pyridine, ndi mankhwala achilengedwe.
Ubwino:
3-(trifluoromethyl)pyridine ndi madzi opanda mtundu komanso fungo lamphamvu. Amasungunuka muzinthu zambiri zosungunulira organic monga ethanol, dimethylformamide, ndi dimethyl sulfoxide.
Gwiritsani ntchito:
3- (trifluoromethyl) pyridine imagwiritsidwa ntchito kwambiri ngati zosungunulira, zosungunulira ndi zotulutsa mu organic synthesis. Itha kugwiritsidwa ntchito ngati reagent ya boron chloride pakuphatikizika kwa ma alcohols, acids, ndi zotumphukira za ester. Itha kugwiritsidwanso ntchito ngati sodium hydroxide-catalyzed borate esterification reagent ya aldehydes ndi ketoni.
Njira:
Pali njira zingapo zokonzekera 3-(trifluoromethyl)pyridine. Njira yodziwika bwino ndiyo kupeza mankhwalawa potengera pyridine ndi trifluoromethylsulfonyl fluoride. Pyridine idasungunuka mu ether solvent, kenako trifluoromethylsulfonyl fluoride idawonjezedwa pang'onopang'ono. Zomwe zimachitika nthawi zambiri zimachitika pakatentha kwambiri ndipo zimafuna mpweya wokwanira kuti mupewe kufalikira kwa mpweya wapoizoni.
Chidziwitso cha Chitetezo: Ndi madzi oyaka omwe amatha kuyatsa moto mosavuta akakhala pamoto kapena kutentha kwambiri. Komanso ndi organic zosungunulira zomwe zingakhudze khungu, maso, ndi kupuma. Magolovesi oteteza, magalasi, ndi zida zopumira ziyenera kuvalidwa panthawi yogwira ntchito, ndipo opaleshoniyo iyenera kuchitidwa pamalo opuma mpweya wabwino.
