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

Ethyl 4,4-difluoro-3-oxobutyrate ili ndi kapangidwe komwe gulu la difluoromethyl (-CF2) limalumikizidwa ku msana wa β-ketoester, ndipo imodzi mwa ma hydrogen imalowedwa m'malo ndi gulu la ethyl (-C2H5). Kapangidwe kameneka kamakhudza mawonekedwe ake akuthupi ndi a mankhwala. Nthawi zambiri imakhala ngati madzi opanda mtundu wokhala ndi kutentha kozungulira 130°C komanso kuchuluka kwa pafupifupi 1.27 g/cm³. Phala limasungunuka pang'ono m'madzi koma limasungunuka mosavuta mu zosungunulira zachilengedwe monga ethanol ndi acetone. Ntchito Makampani Opangira Fungo: Ethyl 4,4-difluoro-3-oxobutyrate imagwiritsidwa ntchito kwambiri mu gawo la fungo chifukwa cha fungo lake la zipatso. Imagwira ntchito ngati chosakaniza chamtengo wapatali mu zonunkhira, ma cologne, ndi zinthu zina zonunkhira. Kupanga Mankhwala: Phala limagwira ntchito ngati chomangira chosinthika mu kapangidwe ka organic. Limatenga nawo mbali m'machitidwe osiyanasiyana popanga zinthu zomwe ndizofunikira kwambiri m'mafakitale opanga mankhwala ndi agrochemical. Pakati: Mu organic chemistry, ethyl 4,4-difluoro-3-oxobutyrate imagwira ntchito ngati pakati pa kupanga mankhwala ovuta kwambiri, zomwe zimathandiza pakupanga zinthu zatsopano ndi njira zamakemikolo. Kupanga Ethyl 4,4-difluoro-3-oxobutyrate kumatha kupangidwa kudzera m'njira zingapo. Njira imodzi yodziwika bwino imaphatikizapo kuchitapo kanthu pakati pa ethyl acetoacetate ndi 2,2-difluoroethyl bromide pansi pa mikhalidwe yoyambira. Kuchitapo kanthu kumeneku kumabweretsa kupangidwa kwa ethyl 4,4-difluoro-3-oxobutyrate ngati chinthu chachikulu, chomwe kenako chimatha kuyeretsedwa kuti chipeze zokolola zambiri komanso chiyero. Mwachidule, ethyl 4,4-difluoro-3-oxobutyrate ndi chinthu chosinthasintha chofunikira popanga fungo labwino, kupanga mankhwala, ndi ntchito zamafakitale. Kapangidwe kake kosiyana, kuphatikiza kusungunuka ndi kapangidwe kake ka mankhwala, kumapangitsa kuti ikhale yofunika m'magawo osiyanasiyana, zomwe zimathandiza kwambiri pakupanga zinthu zosiyanasiyana zogula ndi mafakitale.
