Isingeniso
I-1,1-dibromo-3,3,3-trifluoroacetone iyinhlanganisela ye-organic enefomula yamakhemikhali i-C3Br2F3O. Okulandelayo incazelo yezakhiwo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha kwenhlanganisela:
Imvelo:
-Ukubukeka: I-1,1-dibromo-3,3,3-trifluoroacetone iwuketshezi oluphuzi olukhanyayo olungenambala noma oluqinile oluyi-crystalline.
-Ukuminyana: 1.98g/cm³
-indawo yokuncibilika: 44-45 ℃
-Indawo yokubilisa: 96-98 ℃
-I-Solubility: Incibilika emanzini, i-ethanol ne-ether.
Sebenzisa:
- I-1,1-dibromo-3,3,3-trifluoroacetone isetshenziswa kakhulu njenge-organic synthesis reagent futhi ingasetshenziswa ukulungisa ezinye izinhlanganisela.
-I-compound ingasetshenziswa futhi njenge-catalyst, i-surfactant, kanye nezicelo zaselabhorethri zokuthola amamitha ama-microwave.
Indlela Yokulungiselela:
I-1,1-dibromo-3,3,3-trifluoroacetone ingalungiswa ngezinyathelo ezilandelayo:
1. Okokuqala, i-acetone isabela ne-bromine trifluoride ukuze ikhiqize i-3,3, 3-trifluoroacetone.
2. Okulandelayo, ngaphansi kwezimo ezifanele, i-3,3,3-trifluoroacetone isabela nge-bromine ukuze ikhiqize i-1,1-dibromo-3,3,3-trifluoroacetone.
Ulwazi Lokuphepha:
I-1,1-dibromo-3,3,3-trifluoroacetone iyinhlanganisela ye-organic bromine enobuthi obuthile kanye nokugqwala. Naka lezi zindaba zokuphepha ezilandelayo uma usebenzisa:
-Gwema ukuthintana ngqo nesikhumba namehlo, gqoka amagilavu okuzivikela, izibuko zokuzivikela kanye nemaski yobuso obuvikelayo uma kunesidingo.
-Sebenzisa endaweni engenawo umoya ukuze ugweme ukuhogela amagesi noma umhwamuko.
-Gwema ukuthintana nama-oxidants nezinto ezivuthayo ngesikhathi sokugcina, futhi uzibeke esitsheni esivaliwe, kude nemithombo yomlilo kanye nezindawo zokushisa okuphezulu.
-Gwema izinhlansi kanye nogesi omile ngesikhathi sokusetshenziswa ukuze uvimbele umlilo noma ukuqhuma.
Sicela uqaphele ukuthi i-1,1-dibromo-3,3,3-trifluoroacetone iyi-reagent yaselabhorethri yochwepheshe, engasetshenziswa kuphela ochwepheshe ngaphansi kwezimo ezifanele futhi akufanele isetshenziswe noma isingathwe ngokuthanda kwakhe.
