Trifluoroacetylacetone CAS:367-57-7

Trifluoroacetylacetone (TFAA) ke motsoako o feto-fetohang o nang le thepa e ikhethang ea lik'hemik'hale tse tlatsetsang ts'ebelisong ea oona e pharaletseng lits'ebetsong tse fapaneng tsa indasteri. Thepa TFAA e khetholloa ka sebopeho sa eona sa limolek'hule, se kenyeletsang sehlopha sa trifluoromethyl (-CF3) se hoketsoeng moralo oa diketone. Tokisetso ena e fana ka botsitso bo hlokomelehang le karabelo ho motsoako, e leng se etsang hore o lokele liketso le lits'ebetso tse fapaneng tsa lik'hemik'hale. TFAA hangata e teng e le mokelikeli o tsitsitseng, o se nang 'mala o nang le ntlha e belang ea hoo e ka bang 120°C mme e bontša ho qhibiliha ho itekanetseng ho li-solvents tsa polar tse kang acetone le ethanol. Ho tsitsa ha eona tlas'a maemo a mangata ho lumella ts'ebeliso ea eona lipatlisisong tsa thuto le liindastering. Sebedisa Ts'ebetso ea Organic: TFAA e sebetsa e le reagent ea bohlokoa ho tsoakong ea organic, haholo-holo ho kenyelletsong ea lihlopha tsa trifluoromethyl ho limolek'hule tsa organic. 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 Khokahano: K'hemistri ea khokahano, TFAA e sebetsa e le ligand ka lebaka la boteng ba lihlopha tsa carbonyl le trifluoromethyl, li theha li-complex tse tsitsitseng tse nang le li-ion tsa tšepe. Metswako ena e fumana ditshebediso ho di-catalyst, di-molecular sensor, le jwalo ka di-intermediate ho kopantsweng ha meralo ya metal-organic (MOFs). Catalysis: TFAA e sebediswa e le catalyst diphetohong tse fapaneng tsa organic, ho kenyeletswa le aldol condensations, nucleophilic e eketsang, le di-reaction tsa Michael. Bokgoni ba yona ba ho ntlafatsa sekgahla sa karabelo le kgetho bo e etsa hore e be ya bohlokwa diindastering tsa meriana le tsa dikhemikhale tse ntle. Synthesis Trifluoroacetylacetone e etswa ka karabelo ya trifluoroacetic acid ka acetylacetone tlasa maemo a laolwang. Tshebetso ya esterification e fella ka TFAA e le mokelikeli o tsitsitseng, o se nang mmala, o ka hlwekiswang ka distillation kapa solvent extraction ho fihlela bohlweki bo phahameng bo loketseng ditshebediso tsa indasteri. Tsela e otlolohileng ya synthesis le ho fumaneha ha thepa e tala di kenya letsoho ho theheng ha yona ka ditjeo le tshebediso e pharaletseng dipatlisisong tsa thuto le ditsamaisong tsa indasteri. Ka bokhutšoanyane, trifluoroacetylacetone ke motsoako o feto-fetohang o nang le ditshebediso tsa bohlokwa ho kopantsweng ha organic, k'hemistri ya kgokagano, le catalysis. Thepa ea eona e ikhethang ea lik'hemik'hale, ho kenyeletsoa botsitso le ts'ebetso ea eona, e nolofalletsa tšebeliso ea eona e le motheo oa motheo oa nts'etsopele ea thepa e tsoetseng pele, meriana le lik'hemik'hale tse ikhethileng, e tšehetsa tsoelo-pele mafapheng a fapaneng a indasteri le lipatlisiso tsa mahlale.
