Mawu Oyamba
2-fluoro-3-methylpyrridine (2-fluoro-3-methylpyrridine) ndi organic pawiri ndi mankhwala chilinganizo C6H6FN.
Chilengedwe:
2-fluoro-3-methylpyridine ndi madzi opanda mtundu komanso fungo loipa. Imasinthasintha kutentha komanso kusungunuka mu zosungunulira za organic monga ethanol ndi ether. Ili ndi malo osungunuka a -31 ° C ndi malo owira 129 ° C.
Gwiritsani ntchito:
2-fluoro-3-methylpyridine ali ndi ntchito zosiyanasiyana mu organic synthesis. Ndiwopakatikati mwazinthu zambiri zofunikira ndipo angagwiritsidwe ntchito pokonzekera mankhwala osiyanasiyana, mankhwala ophera tizilombo ndi zida zogwirira ntchito.
Njira:
Kukonzekera kwa 2-fluoro-3-methylpyriridine nthawi zambiri kumapezeka pochita pyridine ndi mpweya wa fluorine. Mu sitepe yeniyeni, mpweya wa pyridine ndi fluorine amachitidwa ndi chothandizira pansi pa zochitika zoyenera kuti apeze 2-fluoro-3-methylpyriridine.
Zambiri Zachitetezo:
2-fluoro-3-methylpyridine imakwiyitsa ndipo imatha kuyambitsa mkwiyo m'maso, khungu, ndi kupuma. Mukamagwiritsa ntchito, samalani kuti musagwirizane ndi khungu ndi maso, komanso kuti mukhale ndi mpweya wabwino. Pakusamalira ndi kusunga, njira zoyenera zogwirira ntchito zotetezeka ziyenera kutsatiridwa kuti zipewe kukhudzidwa ndi moto ndi malo otentha kwambiri. Ngati mwakumana mwangozi, muzimutsuka nthawi yomweyo ndi madzi ambiri ndikupempha thandizo lachipatala.
