Mawu Oyamba
1-Bromo-3,3,3-trifluoroacetone. Zotsatirazi ndizofotokozera za katundu, ntchito, njira zokonzekera ndi chidziwitso cha chitetezo cha gululi:
Ubwino:
1-Bromo-3,3,3-trifluoroacetone ndi madzi opanda mtundu okhala ndi fungo lapadera lomwe limatentha kutentha komanso kupanikizika. Amasungunuka mu ma alcohols, ethers, ndi ma organic solvents, komanso osasungunuka m'madzi. Chophatikizikacho chimakhala ndi kuthamanga kwambiri kwa nthunzi komanso kusakhazikika.
Gwiritsani ntchito:
1-Bromo-3,3,3-trifluoroacetone ili ndi ntchito zosiyanasiyana pamakampani opanga mankhwala. Chimodzi mwazinthu zazikulu zomwe zimagwiritsidwa ntchito ndi monga chopangira chapakatikati cha fluoroacetone. Amagwiritsidwanso ntchito ngati chothandizira kupanga organic synthesis komanso ngati surfactant.
Njira:
Kaphatikizidwe ka 1-bromo-3,3,3-trifluoroacetone nthawi zambiri imachitika ndi njira ya bromohydrofluoric acid. Acetone imayendetsedwa ndi hydrofluoric acid mu reactor kuti ipeze bromoacetone. Kenako, sodium bromidi anawonjezedwa kwa anachita osakaniza, ndi bromination anachita kuti apeze 1-bromo-3,3,3-trifluoroacetone. Zomwe zimapangidwira zimapezedwa ndi distillation ndi kuyeretsedwa.
Zambiri Zachitetezo:
1-Bromo-3,3,3-trifluoroacetone imakwiyitsa ndipo imatha kukhala ndi zotsatira zoyipa m'maso, pakhungu, komanso pamapumira. Mukamagwiritsa ntchito, muyenera kutsatira njira zoyenera zodzitetezera monga zovala za maso, magolovesi, ndi zopumira. Iyenera kugwiritsidwa ntchito pamalo abwino mpweya wabwino ndi kupewa kukhudzana ndi zinthu monga amphamvu okosijeni.
