trifluoroethyl methacrylate CAS:352-87-4

TFEMA imadziwika ndi kapangidwe kake ka molekyulu, komwe kali ndi msana wa methacrylate ester wolumikizidwa ndi gulu la trifluoroethyl (-CF3CH2). Kapangidwe kameneka kamapereka mawonekedwe odziwika bwino ku TFEMA, kuphatikizapo reactivity yayikulu mu njira zopopera ndi kukhazikika kwapadera mu ma polima omwe amachokera. TFEMA nthawi zambiri imakhala ngati madzi owoneka bwino, opanda mtundu wokhala ndi kutentha kotentha pafupifupi 120°C ndipo imasonyeza kusungunuka pang'ono mu zosungunulira zachilengedwe monga acetone ndi ethanol. Kuphatikiza kwake kwapadera kwa fluorination ndi ntchito ya acrylic kumawonjezera ntchito yake m'malo osiyanasiyana a mankhwala ndi ntchito. Kugwiritsa Ntchito Polymer Chemistry: TFEMA imagwira ntchito ngati monomer yofunika kwambiri pakupanga ma polima ndi ma copolymers opangidwa ndi fluorinated. Kuphatikizidwa kwake mu unyolo wa polima kumabweretsa zinthu zabwino monga hydrophobicity yabwino, kukana kwa mankhwala motsutsana ndi ma acid ndi maziko, komanso kukhazikika kwa kutentha. Makhalidwe amenewa amapangitsa ma polima ochokera ku TFEMA kukhala abwino kwambiri pakugwiritsa ntchito mu zokutira, zomatira, ndi zipangizo zapadera zomwe zimafuna kulimba pansi pa mikhalidwe yovuta. Kusintha kwa Pamwamba: TFEMA imagwiritsidwa ntchito posintha pamwamba kuti ipereke zinthu zinazake ku zipangizo. Mwa kupolima ndi ma monomers ena, TFEMA imalola kupanga malo okhala ndi magwiridwe antchito apadera, monga mphamvu zotsutsana ndi kuipitsa muzipangizo zamankhwala, kumamatira bwino mu zokutira, komanso mphamvu zowongolera zamagetsi muzipangizo zamagetsi. Kugwiritsa Ntchito Zamankhwala: Mu kafukufuku wa zamankhwala ndi ntchito, ma polima opangidwa ndi TFEMA amagwiritsidwa ntchito chifukwa cha kugwirizana kwawo ndi chilengedwe komanso kukana kuwonongeka kwa zamoyo. Amagwiritsidwa ntchito muzipangizo zamankhwala, machitidwe operekera mankhwala, ndi ma scaffolds opanga minofu komwe kuphatikiza kwa fluorination ndi ntchito ya acrylic kumapereka kukhazikika ndi kuthekera kotulutsa kolamulidwa. Kupanga Trifluoroethyl methacrylate imapangidwa kudzera mu esterification reaction ya methacrylic acid ndi trifluoroethanol pansi pa mikhalidwe yolamulidwa. Njirayi imaphatikizapo kusungunuka kwa ma reagents awa kuti apange TFEMA, yomwe pambuyo pake imayeretsedwa ndi distillation kapena solvent extraction kuti ipeze chiyero chokwanira chogwiritsidwa ntchito m'mafakitale. Njira yosavuta yopangira komanso kupezeka kwa zinthu zoyambira zimathandiza kuti TFEMA ikhale yotsika mtengo komanso yogwiritsidwa ntchito kwambiri mu polymer chemistry ndi madera ena ofanana. Mwachidule, trifluoroethyl methacrylate ndi mankhwala ogwiritsidwa ntchito mosiyanasiyana omwe amagwiritsidwa ntchito kwambiri mu polymer chemistry, kusintha kwa pamwamba, ndi kafukufuku wa zamankhwala. Makhalidwe ake apadera a mankhwala, kuphatikizapo kapangidwe ka fluorinated ndi ntchito ya acrylic, zimathandiza kupanga zipangizo zamakono zokhala ndi makhalidwe okonzedwa, kuthandizira zatsopano m'magawo osiyanasiyana a mafakitale ndi maphunziro asayansi.
