Tlhaho:
-Ponahalo: 1,1-dibromo-3,3,3-trifluoroacetone ke mokelikeli o mosehla o se nang mebala kapa o tiileng oa crystalline.
- Boima: 1.98g/cm³
- sebaka se qhibilihang: 44-45 ℃
Sebaka se belang: 96-98 ℃
-Solubility: Ho qhibiliha ka metsing, ethanol le ether.
Sebelisa:
- 1,1-dibromo-3,3,3-trifluoroacetone e sebelisoa haholo-holo e le organic synthesis reagent mme e ka sebelisoa ho lokisa metsoako e meng.
-Motsoako o ka boela oa sebelisoa e le catalyst, surfactant, le lits'ebetsong tsa laboratori bakeng sa qeto ea limithara tsa microwave.
Mokhoa oa ho itokisa:
1,1-dibromo-3,3,3-trifluoroacetone e ka lokisoa ka mehato e latelang:
1. Ntlha ea pele, acetone e sebetsana le bromine trifluoride ho hlahisa 3,3, 3-trifluoroacetone.
2. Ka mor'a moo, tlas'a maemo a loketseng, 3,3,3-trifluoroacetone e itšoara ka bromine ho hlahisa 1,1-dibromo-3,3,3-trifluoroacetone.
Lintlha tsa Tšireletseho:
1,1-dibromo-3,3,3-trifluoroacetone ke motsoako oa bromine oa organic o nang le chefo e itseng le ho senya. Ela hloko lintlha tse latelang tsa polokeho ha u sebelisa:
- Qoba ho kopana ka ho toba le letlalo le mahlo, roala liatlana tse sireletsang, likhalase tse sireletsang le mask a sireletsang sefahleho ha ho hlokahala.
-Sebetsa ka moea o thibelang moea ho qoba ho hema likhase kapa mouoane.
- Qoba ho kopana le li-oxidants le lintho tse tukang nakong ea polokelo, 'me u li behe ka setsing se koetsoeng, hole le mehloli ea mollo le libaka tse phahameng tsa mocheso.
- Qoba litlhase le motlakase o tsitsitseng nakong ea tšebeliso ho thibela mollo kapa ho phatloha.
Ka kopo hlokomela hore 1,1-dibromo-3,3,3-trifluoroacetone ke setsebi sa laboratori ea litsebi, e ka sebelisoang feela ke litsebi tlas'a maemo a loketseng 'me ha ea lokela ho sebelisoa kapa ho tšoaroa ka thato.
