Okwu mmalite
1-Bromo-3,3,3-trifluoroacetone. Ndị a bụ mmalite nke akụrụngwa, ojiji, ụzọ nkwadebe na ozi nchekwa nke ogige a:
Ogo:
1-Bromo-3,3,3-trifluoroacetone bụ mmiri mmiri na-enweghị agba nke nwere isi ísì pụrụ iche na okpomọkụ na nrụgide. Ọ na-agbaze na alcohols, ethers, na ụfọdụ ihe mgbaze organic, na mmiri na-esighi ike. Ngwakọta ahụ nwere oke uzuoku na volatility.
Jiri:
1-Bromo-3,3,3-trifluoroacetone nwere ọtụtụ ngwa ngwa na ụlọ ọrụ kemịkalụ. Otu n'ime isi ihe eji eme ihe bụ dị ka etiti sịntetik maka fluoroacetone. A na-ejikwa ya dị ka ihe na-akpali akpali maka njikọ organic na dị ka surfactant.
Usoro:
A na-emekarị njikọ nke 1-bromo-3,3,3-trifluoroacetone site na usoro bromohydrofluoric acid. A na-emeghachi acetone na hydrofluoric acid na reactor iji nweta bromoacetone. Mgbe ahụ, a na-agbakwunye sodium bromide na ngwakọta mmeghachi omume, a na-emekwa mmeghachi omume bromination iji nweta 1-bromo-3,3,3-trifluoroacetone. A na-enweta ngwaahịa ezubere iche site na distillation na ịdị ọcha.
Ozi nchekwa:
1-Bromo-3,3,3-trifluoroacetone na-akpasu iwe ma nwee ike inwe mmetụta na-akpasu iwe na anya, akpụkpọ ahụ, na usoro iku ume. Mgbe ị na-eji ya, ekwesịrị iwere usoro nchedo onwe onye kwesịrị ekwesị dị ka uwe mkpuchi, uwe aka, na ihe iku ume. Ekwesịrị iji ya na ebe ikuku na-ekpo ọkụ ma zere kọntaktị na ihe ndị dị ka oxidants siri ike.
