I-Ethyl 4,4-difluoro-3-oxobutyrate CAS:352-24-9

I-Ethyl 4,4-difluoro-3-oxobutyrate inesakhiwo lapho iqembu le-difluoromethyl (-CF2) linamathele kumgogodla we-β-ketoester, kanti elinye lama-hydrogen lithathelwa indawo yiqembu le-ethyl (-C2H5). Lokhu kwakheka kwesakhiwo kuthonya izici zalo zomzimba nezamakhemikhali. Ngokuvamile likhona njengoketshezi olungenambala olunephuzu lokubila elizungeze i-130°C kanye nobuningi obungaba ngu-1.27 g/cm³. Inhlanganisela ayincibiliki emanzini kodwa incibilika kalula ezinyibilikisini eziphilayo ezifana ne-ethanol ne-acetone. Ukusetshenziswa Imboni Yephunga: I-Ethyl 4,4-difluoro-3-oxobutyrate isetshenziswa kabanzi emkhakheni wephunga ngenxa yephunga layo lezithelo. Isebenza njengesithako esibalulekile kumakha, ama-cologne, kanye neminye imikhiqizo enephunga elimnandi. Ukwenziwa Kwamakhemikhali: Inhlanganisela isebenza njengebhulokhi yokwakha eliguquguqukayo ekuhlanganisweni kwezinto eziphilayo. Ihlanganyela ekuphenduleni okuhlukahlukene ukukhiqiza izinto ezisetshenziswayo ezibalulekile ezimbonini zemithi kanye nezolimo. Okuphakathi: Kumakhemikhali e-organic, i-ethyl 4,4-difluoro-3-oxobutyrate isebenza njengesixhumi sokuhlanganiswa kwamakhemikhali ayinkimbinkimbi kakhulu, okufaka isandla ekuthuthukisweni kwezinto ezintsha kanye nezinqubo zamakhemikhali. Ukwenziwa kwe-Ethyl 4,4-difluoro-3-oxobutyrate kungenziwa ngezindlela eziningana. Indlela eyodwa evamile ihilela ukusabela phakathi kwe-ethyl acetoacetate kanye ne-2,2-difluoroethyl bromide ngaphansi kwezimo eziyisisekelo. Lokhu kusabela kuholela ekwakhekeni kwe-ethyl 4,4-difluoro-3-oxobutyrate njengomkhiqizo oyinhloko, ongabe usuhlanzwa ukuze uthole isivuno esiphezulu kanye nobumsulwa. Ngamafuphi, i-ethyl 4,4-difluoro-3-oxobutyrate iyinhlanganisela eguquguqukayo ebalulekile ekudalweni kwamakha, ukwenziwa kwamakhemikhali, kanye nokusetshenziswa kwezimboni. Izakhiwo zayo ezihlukile, okuhlanganisa ukuncibilika kanye nesakhiwo esithile samakhemikhali, zenza kube yigugu kuzo zonke imikhakha ehlukahlukene, okunegalelo elikhulu ekwakhiweni kwemikhiqizo eyahlukahlukene yabathengi neyezimboni.
