Mawu Oyamba
2-Fluoronicotinic acid ndi organic pawiri ndi mankhwala chilinganizo C6H4FNO2. Ndiwochokera ku nicotinic acid (3-oxopyridine-4-carboxylic acid) mu kapangidwe kake ka mankhwala, momwe atomu imodzi ya haidrojeni imasinthidwa ndi atomu ya fluorine.
2-Fluoronicotinic acid ndi cholimba cha crystalline choyera chomwe chimakhala chokhazikika pa kutentha kozungulira. Ili ndi kusungunuka kwabwino ndipo imatha kusungunuka m'madzi. Ndi asidi ofooka omwe amapanga mchere ndi zitsulo.
2-Fluoronicotinic acid imagwiritsidwa ntchito kwambiri m'magawo ena. Itha kugwiritsidwa ntchito ngati chofunikira chapakatikati mu kaphatikizidwe ka organic pokonzekera mankhwala ena kapena mankhwala. Kuphatikiza apo, itha kugwiritsidwanso ntchito muzitsulo zogwirizanitsa zitsulo ndi machitidwe othandizira.
Pali njira zingapo zopangira 2-Fluoronicotinic acid. Njira yodziwika bwino ndi fluorination ya nicotinic acid. A njira wamba ndi zimene fluorinating reagent, monga hydrogen fluoride kapena trifluoroacetic asidi, ndi nicotinic asidi pansi acidic mikhalidwe kupereka 2-Fluoronicotinic asidi.
Kuganizira zachitetezo kumafunika pogwira 2-Fluoronicotinic acid. Ndi mankhwala owononga ndipo ayenera kuvala ndi magolovesi oteteza ndi magalasi oyenera. Pewani kulowetsa fumbi kapena nthunzi yake mukamagwiritsa ntchito, ndipo sungani malo a labotale omwe ali ndi mpweya wabwino. Posunga, iyenera kusungidwa mu chidebe chowuma, chosindikizidwa, kutali ndi zoyaka zoyaka ndi ma oxygen.
Nthawi zambiri, 2-Fluoronicotinic acid ndi organic pawiri ndi kusungunuka kwabwino komanso kukhazikika. Lili ndi ntchito zambiri zomwe zimagwiritsidwa ntchito mu organic synthesis, kugwirizanitsa zitsulo ndi machitidwe othandizira, koma njira zotetezera ziyenera kuchitidwa panthawi yosamalira ndi kusunga.
