Mawu Oyamba
6-Chloronicotinaldehyde (yomwe imadziwikanso kuti 2,4,6-chlorobenzoic acid aldehyde) ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha 6-chloronicotinaldehyde:
Katundu: 6-Chloronicotinaldehyde ndi kristalo wopanda mtundu kapena woyera crystalline ufa wokhala ndi fungo loyipa. Ali ndi kutsutsana pang'ono ndipo amatha kusungunuka muzinthu zambiri zosungunulira monga ma alcohols, ethers, ndi ketoni. Ndi pafupifupi osasungunuka m'madzi koma amatha kusungunuka mu zosungunulira za organic.
Ntchito: 6-Chloronicotinaldehyde nthawi zambiri amagwiritsidwa ntchito ngati reagent komanso wapakatikati mu kaphatikizidwe ka organic. Amagwiritsidwa ntchito ngati zopangira mankhwala ophera tizilombo, herbicides, ndi fungicides m'gawo laulimi.
Kukonzekera njira: 6-chloronicotinaldehyde akhoza analandira ndi zimene benzoyl kolorayidi ndi zotayidwa kolorayidi. Zochita zinthu angathe kuchitidwa firiji. Njira yeniyeni ya kaphatikizidwe ndi motere:
C6H5COCl + AlCl3 -> C6H4ClCOCl + HCl
C6H4ClCOCl + HCl -> C7H3Cl3O + CO2 + HCl
Zambiri zachitetezo: 6-Chloronicotinaldehyde imakwiyitsa, pewani kukhudzana ndi khungu ndi maso. Njira zodzitetezera ziyenera kuchitidwa mukamagwiritsa ntchito, monga kuvala magolovesi, zovala zodzitchinjiriza, ndi zobvala zodzitetezera. Pewani kulowetsa nthunzi kapena fumbi pamene mukugwira ntchito. Mukasunga ndi kunyamula 6-chloronicotinal, tsatirani njira zoyenera zogwirira ntchito ndikuzisunga motetezeka mu chidebe chomwe mwasankha. Potaya zinyalala, ziyenera kutayidwa moyenera malinga ndi malamulo a m’deralo.
