Mawu Oyamba
Ndi organic pawiri ndi mankhwala chilinganizo C6H7FN2. Zotsatirazi ndikuyambitsa zina mwazinthu zake, ntchito, njira ndi chidziwitso chachitetezo:
Chilengedwe:
1. Maonekedwe: Opanda mtundu mpaka wotumbululuka wachikasu wakristalo wolimba.
2. Malo osungunuka: pafupifupi 82-85 ℃.
3. Powira: Pafupifupi 219-221 ℃.
4. Kusungunuka: Kusungunuka mu zosungunulira zambiri za organic monga ethanol, etha ndi dichloromethane.
Gwiritsani ntchito:
Amagwiritsidwa ntchito makamaka ngati wapakatikati mu kaphatikizidwe ka organic. Ikhoza kugwiritsidwa ntchito pokonzekera mitundu yosiyanasiyana ya mankhwala, monga mankhwala, mankhwala ophera tizilombo, utoto ndi ligands. Ilinso ndi phindu lomwe lingagwiritsidwe ntchito pazamankhwala.
Njira:
Nthawi zambiri amapezeka pochita pyridine ndi fluorinating reagent ndi amino reagent chifukwa cha methylation reaction. Njira yeniyeni ya kaphatikizidwe imatha kusinthidwa ndikusinthidwa malinga ndi zosowa zenizeni.
Zambiri Zachitetezo:
1. Zingakhale zokhumudwitsa m'maso, khungu ndi kupuma. Ntchito ayenera kusamala kupewa kukhudzana.
2. Valani zida zodzitetezera zoyenera monga magolovesi, magalasi oteteza chitetezo ndi masks oteteza panthawi yogwira ntchito.
3. Pewani kutulutsa fumbi, utsi ndi mpweya. Malo ogwirira ntchito ayenera kukhala ndi mpweya wabwino.
4. Ngati kukhudzana mwangozi kapena molakwika, ayenera kusamba nthawi yomweyo kapena mankhwala.
