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

Ethyl 4,4,4-trifluoroacetoacetate, yomwe imadziwikanso kuti ethyl trifluoroacetoacetate, ndi madzi opanda mtundu omwe amadziwika ndi fungo lake lakuthwa komanso la zipatso. Ndi formula ya mankhwala C6H6F3O3, imagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana chifukwa cha mawonekedwe ake apadera a mankhwala. Kapangidwe ka Ethyl 4,4,4-trifluoroacetoacetate kamakhala ndi kapangidwe komwe gulu la trifluoromethyl (-CF3) limalumikizidwa ku msana wa β-ketoester, ndipo imodzi mwa ma hydrogen imalowetsedwa ndi gulu la ethyl (-C2H5). Kapangidwe kameneka kamakhudza mawonekedwe ake akuthupi ndi a mankhwala. Nthawi zambiri imawoneka ngati madzi opanda mtundu omwe amawira pafupifupi 120°C komanso kuchuluka kwa pafupifupi 1.35 g/cm³. Ngakhale kuti imasungunuka pang'ono m'madzi, imasungunuka mosavuta mu zosungunulira zachilengedwe monga ethanol ndi acetone. Ntchito Makampani Opangira Fungo: Ethyl 4,4,4-trifluoroacetoacetate ndi yamtengo wapatali kwambiri m'gawo la fungo chifukwa cha fungo lake lakuthwa komanso la zipatso. Amagwiritsidwa ntchito kwambiri mu zonunkhira, ma cologne, ndi zinthu zina zonunkhira kuti apereke fungo losiyana. Kupanga Mankhwala: Chomerachi chimagwira ntchito ngati chosinthira pakati pa kupanga zinthu zachilengedwe. Chimatenga nawo mbali muzochita zosiyanasiyana kuti chipange zinthu zofunikira pa mankhwala, mankhwala a agrochemicals, ndi mankhwala apadera, chifukwa cha momwe chimagwirira ntchito mankhwala mwapadera. Chowonjezera Kukoma: Kuwonjezera pa ntchito yake mu zonunkhira, ethyl 4,4,4-trifluoroacetoacetate imagwiritsidwa ntchito mumakampani azakudya ngati chowonjezera kukoma chifukwa cha fungo lake la zipatso. Kupanga Ethyl 4,4,4-trifluoroacetoacetate kumatha kupangidwa kudzera m'njira zingapo. Njira yodziwika bwino imaphatikizapo kuchitapo kanthu pakati pa ethyl acetoacetate ndi trifluoroacetic acid pansi pa mikhalidwe yolamulidwa. Kuchitapo kanthu kumeneku kumabweretsa ethyl 4,4,4-trifluoroacetoacetate ngati chinthu chachikulu, chomwe chimatha kuyeretsedwa kuti chipeze zokolola zambiri komanso chiyero choyenera kugwiritsidwa ntchito m'mafakitale. Mwachidule, ethyl 4,4,4-trifluoroacetoacetate ndi chinthu chogwiritsidwa ntchito mosiyanasiyana chomwe chimafunika popanga fungo labwino, kupanga mankhwala, komanso kugwiritsa ntchito zinthu zosiyanasiyana m'mafakitale. Makhalidwe ake osiyanasiyana, kuphatikizapo kusungunuka ndi kapangidwe kake ka mankhwala, zimapangitsa kuti ikhale yofunika kwambiri m'magawo osiyanasiyana, zomwe zimathandiza kwambiri pakupanga zinthu zosiyanasiyana zogwiritsidwa ntchito ndi anthu komanso mafakitale.
