ethyl difluoroacetate CAS:454-31-9

Ethyl difluoroacetate (EDA) e khetholloa ka sebopeho sa eona sa limolek'hule, se nang le sehlopha sa difluoromethyl (-CF2COOEt) se hokahaneng le karolo ea ethyl ester. Sebopeho sena se fana ka botsitso bo boholo le karabelo ho EDA, e leng se etsang hore e lokele mefuta e mengata ea lik'hemik'hale le lits'ebetso. Hangata EDA e teng e le mokelikeli o hlakileng, o se nang 'mala o nang le ntlha e belang e ka bang 100°C 'me e bontša ho qhibiliha ho hotle litharollong tsa tlhaho tse kang acetone le ethyl acetate. Ho tsitsa ha eona tlas'a maemo a fapaneng ho lumella tšebeliso ea eona e sebetsang lipatlisisong tsa laboratori le lits'ebetsong tsa indasteri. Tšebeliso ea Organic Synthesis: EDA e sebetsa e le motheo oa bohlokoa oa ho theha metsoako ea tlhaho, haholo-holo ho kenyelletsong ea lihlopha tsa difluoromethyl limolek'huleng tsa tlhaho. Bokhoni bona bo bohlokoa bakeng sa ho nts'etsapele meriana, lik'hemik'hale tsa temo, le lik'hemik'hale tse ikhethang tse nang le ts'ebetso e ntlafalitsoeng ea baeloji le botsitso ba lik'hemik'hale. Khemistri ea Meriana: Litšebelisong tsa meriana, EDA e sebelisoa e le selelekela sa ho kopanya metsoako e sebetsang ea meriana (API) ka lebaka la bokhoni ba eona ba ho fana ka thepa e lakatsehang ea meriana. E bapala karolo ea bohlokoa k'hemistring ea meriana ka ho nolofalletsa phetoho ea limolek'hule tsa meriana ho ntlafatsa katleho le ho fokotsa ho hloleha ha metabolism. Lik'hemik'hale tse Ikhethang: EDA e fumana ts'ebeliso tlhahisong ea lik'hemik'hale tse ikhethang joalo ka li-surfactants, li-plasticizer, le li-intermediate tse rarahaneng tse sebelisoang tlhahisong ea lik'hemik'hale tsa temo le lik'hemik'hale tse ntle. Ho feto-fetoha ha eona liphetohong tsa lik'hemik'hale ho e etsa ea bohlokoa mefuteng moo ho hlokahalang taolo e nepahetseng holim'a sebopeho le ts'ebetso ea limolek'hule. Tlhahiso ea Ethyl difluoroacetate e hlahisoa ka karabelo ea esterification ea difluoroacetic acid ka ethanol. Ts'ebetso ena e kenyelletsa ho koaheloa ha difluoroacetic acid ka ethanol tlas'a maemo a laoloang ho theha EDA. Karabelo hangata e susumetsoa ke li-acid kapa metheo ho nolofalletsa ho thehoa ha ester bond. Mekhoa ea ho hloekisa joalo ka ho qhibilihisa kapa ho ntša solvent e sebelisoa ho fumana EDA ka bohloeki bo phahameng bo loketseng lits'ebetsong tsa indasteri. Tsela e otlolohileng ea tlhahiso le ho fumaneha ha thepa e tala ho tlatsetsa ho katlehong ea eona ea litšenyehelo le ts'ebeliso e pharaletseng lipatlisisong tsa thuto le lits'ebetsong tsa indasteri. Ka kakaretso, ethyl difluoroacetate ke motsoako o feto-fetohang o nang le ts'ebeliso ea bohlokoa tlhahisong ea lintho tse phelang, k'hemistri ea meriana, le tlhahiso ea lik'hemik'hale tse ikhethang. Litšobotsi tsa eona tse ikhethang tsa lik'hemik'hale, ho kenyeletsoa botsitso, ts'ebetso ea ho sebetsa hape, le bonolo ba ho kopanya, li kenya letsoho bohlokoa ba eona ho ntšetseng pele mahlale a theknoloji mafapheng a fapaneng a indasteri le mafapheng a saense.
