ethyl 4,4,4-trifluoroacetoacetate CAS:372-31-6

Ethyl 4,4,4-trifluoroacetoacetate, e tsejoang hape e le ethyl trifluoroacetoacetate, ke mokelikeli o se nang 'mala o khetholloang ke monko oa oona o bohale, o kang litholoana. Ka foromo ea lik'hemik'hale C6H6F3O3, e phetha karolo ea bohlokoa lits'ebetsong tse fapaneng tsa indasteri ka lebaka la litšobotsi tsa eona tse ikhethang tsa lik'hemik'hale. Thepa Ethyl 4,4,4-trifluoroacetoacetate e na le sebopeho moo sehlopha sa trifluoromethyl (-CF3) se hoketsoeng mokokotlong oa β-ketoester, 'me e' ngoe ea li-hydrogen e nkeloa sebaka ke sehlopha sa ethyl (-C2H5). Tokisetso ena ea sebopeho e susumetsa litšobotsi tsa eona tsa 'mele le tsa lik'hemik'hale. Hangata e hlaha e le mokelikeli o se nang 'mala o nang le ntlha e belang e ka bang 120°C le boima ba hoo e ka bang 1.35 g/cm³. Leha e qhibiliha hanyane ka metsing, e qhibiliha habonolo ka har'a li-solvents tsa tlhaho tse kang ethanol le acetone. Tšebeliso Indasteri ea Monko: Ethyl 4,4,4-trifluoroacetoacetate e ratoa haholo lefapheng la monko o monate ka lebaka la monko oa eona o bohale, o kang litholoana. E sebelisoa haholo libanong tse nkhang hamonate, li-cologne, le lihlahisoa tse ling tse nkhang hamonate ho fana ka lintlha tse ikhethang tsa monko. Ho kopanya lik'hemik'hale: Motsoako ona o sebetsa e le setsi se sebetsang ka mokhoa o feto-fetohang ho tsoakaneng ha lintho tse phelang. O nka karolo liketsong tse fapaneng ho hlahisa lintho tse bohlokoa bakeng sa meriana, lik'hemik'hale tsa temo le lik'hemik'hale tse ikhethang, ka lebaka la ts'ebetso ea eona e ikhethang ea lik'hemik'hale. Sesebelisoa sa ho ntlafatsa tatso: Ntle le karolo ea sona libanong, ethyl 4,4,4-trifluoroacetoacetate e sebelisoa indastering ea lijo e le sesebelisoa sa ho ntlafatsa tatso ka lebaka la monko oa eona o monate oa litholoana. Sesebelisoa sa ho kopanya Ethyl 4,4,4-trifluoroacetoacetate e ka etsoa ka mekhoa e 'maloa. Mokhoa o tloaelehileng o kenyelletsa karabelo pakeng tsa ethyl acetoacetate le trifluoroacetic acid tlas'a maemo a laoloang. Karabelo ena e hlahisa ethyl 4,4,4-trifluoroacetoacetate e le sehlahisoa se seholo, se ka hloekisoang ho fihlela chai e phahameng le bohloeki bo loketseng lits'ebetso tsa indasteri. Ka bokhutšoanyane, ethyl 4,4,4-trifluoroacetoacetate ke motsoako o feto-fetohang o hlokahalang tlhahisong ea monko o monate, tlhahiso ea lik'hemik'hale, le lits'ebetsong tse fapaneng tsa indasteri. Litšobotsi tsa eona tse ikhethang, ho kenyeletsoa ho qhibiliha le sebopeho se itseng sa lik'hemik'hale, li etsa hore e be ea bohlokoa makaleng a mangata, e leng se tlatsetsang haholo ho thehoeng ha lihlahisoa tse fapaneng tsa bareki le tsa indasteri.
