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

I-Ethyl 4,4,4-trifluoroacetoacetate, eyaziwa nangokuthi i-ethyl trifluoroacetoacetate, iwuketshezi olungenambala olubonakala ngephunga lalo elibukhali nelinjengezithelo. Ngefomula yamakhemikhali i-C6H6F3O3, isebenza izindima ezibalulekile ekusetshenzisweni okuhlukahlukene kwezimboni ngenxa yezakhiwo zayo zamakhemikhali ezihlukile. Izakhiwo I-Ethyl 4,4,4-trifluoroacetoacetate inesakhiwo lapho iqembu le-trifluoromethyl (-CF3) linamathele kumgogodla we-β-ketoester, kanti elinye lama-hydrogen lithathelwa indawo yiqembu le-ethyl (-C2H5). Lokhu kuhlelwa kwesakhiwo kuthonya izici zalo zomzimba nezamakhemikhali. Ngokuvamile livela njengoketshezi olungenambala olunephuzu lokubila elizungeze i-120°C kanye nobuningi obungaba ngu-1.35 g/cm³. Ngenkathi incibilika kancane emanzini, incibilika kalula ezinyibilikisini eziphilayo ezifana ne-ethanol ne-acetone. Ukusetshenziswa Imboni Yephunga: I-Ethyl 4,4,4-trifluoroacetoacetate ibaluleke kakhulu emkhakheni wamakha ngenxa yephunga layo elibukhali nelinjengezithelo. Isetshenziswa kakhulu kuma-perfume, ama-cologne, kanye neminye imikhiqizo enamakha ukuze inikeze amanothi ahlukile okunuka. Ukwenziwa Kwamakhemikhali: Le nhlanganisela isebenza njengesixhumi esiguquguqukayo ekuhlanganisweni kwezinto eziphilayo. Ihlanganyela ekuphenduleni okuhlukahlukene ukuze ikhiqize izinto ezisetshenziswayo ezibalulekile kwezokwelapha, amakhemikhali ezolimo, kanye namakhemikhali akhethekile, ngenxa yokusabela kwayo okuhlukile kwamakhemikhali. Isithuthukisi Sokunambitheka: Ngaphezu kwendima yayo emakhakheni, i-ethyl 4,4,4-trifluoroacetoacetate isetshenziswa embonini yokudla njengesithuthukisi sokunambitheka ngenxa yephunga layo elimnandi. Ukwenziwa I-Ethyl 4,4,4-trifluoroacetoacetate ingenziwa ngezindlela eziningana. Indlela evamile ihilela ukusabela phakathi kwe-ethyl acetoacetate kanye ne-trifluoroacetic acid ngaphansi kwezimo ezilawulwayo. Lokhu kusabela kuveza i-ethyl 4,4,4-trifluoroacetoacetate njengomkhiqizo oyinhloko, ongabe usuhlanzwa ukuze kutholakale isivuno esiphezulu kanye nobumsulwa obufanele ukusetshenziswa kwezimboni. Ngamafuphi, i-ethyl 4,4,4-trifluoroacetoacetate iyinhlanganisela eguquguqukayo ebalulekile ekudalweni kwamakha, ukwenziwa kwamakhemikhali, kanye nokusetshenziswa okuhlukahlukene kwezimboni. Izakhiwo zayo ezihlukile, okuhlanganisa ukuncibilika kanye nesakhiwo esithile samakhemikhali, ziyenza ibe yinto ebalulekile emikhakheni eminingi, inegalelo elikhulu ekwakhiweni kwemikhiqizo eyahlukahlukene yabathengi neyezimboni.
