Mawu Oyamba
4-Chloro-4'-fluorobutanone ndi organic pawiri. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera, ndi chidziwitso cha chitetezo cha gululi:
Ubwino:
- Maonekedwe: 4-Chloro-4′-fluorophenone ndi madzi opanda mtundu kapena opepuka achikasu.
- Kusungunuka: Kutha kusungunuka mu zosungunulira zina monga chloroform, ma alcohols, ndi ethers.
Gwiritsani ntchito:
- Paulimi, itha kugwiritsidwa ntchito kupanga mankhwala ophera tizilombo ndi ma fungicides.
Njira:
- 4-Chloro-4'-fluorobutanone ikhoza kukonzedwa ndi zochita za phenylbutanone ndi chlorine ndi fluorine mankhwala.
- Njira yokonzekera yodziwika bwino ndikukonzekera 4-chlorophenone pogwiritsa ntchito phenylbutanone ndi hydrogen chloride, kenako ndi hydrogen fluoride reaction kuti mupeze 4-chloro-4′-fluorobutanone. Zimene zimachitika kawirikawiri ikuchitika pa yoyenera kutentha ndi mavuto.
Zambiri Zachitetezo:
- 4-Chloro-4'-fluorobutanone ndi mankhwala omwe amayenera kugwiritsidwa ntchito motsatira ndondomeko zoyenera zoyendetsera chitetezo, monga kuvala magolovesi otetezera, magalasi, ndi zovala zotetezera.
- Mukamachita njirayi, pewani kutulutsa nthunzi yake kapena kukhudza khungu ndi maso.
- Fufuzani chithandizo chamankhwala mwamsanga mukamalowetsedwa, kutulutsa mpweya, kapena kukhudzana ndi khungu ndi khungu ndikupereka Chemical Data Sheet kwa dokotala wanu kuti afotokoze.
Mukamagwiritsa ntchito mankhwala aliwonse, ndikofunikira kutsatira kasamalidwe koyenera komanso kasamalidwe ka chitetezo ndikuchitapo kanthu moyenera.
