2,2,2-Trifluoroethyl methacrylate CAS:352-87-4

2,2,2-Trifluoroethyl methacrylate (TFEMA) ndi mankhwala osakanikirana okhala ndi zinthu zosiyanasiyana zomwe zimapangitsa kuti ikhale yofunika kwambiri m'mafakitale osiyanasiyana. Zinthu TFEMA imadziwika ndi kapangidwe kake ka mankhwala, komwe kumaphatikizapo gulu la trifluoromethyl (-CF3) lolumikizidwa ku msana wa ethyl methacrylate. Kapangidwe ka mamolekyulu kameneka kamapatsa TFEMA zinthu zapadera monga mphamvu yochepa pamwamba komanso kusowa kwa madzi okwanira, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazinthu zomwe zimafuna zinthu zomwe zimalimbana ndi mankhwala komanso zachilengedwe. TFEMA ndi madzi omveka bwino, opanda mtundu wokhala ndi kutentha kwa pafupifupi 100°C ndipo amatha kusakanikirana ndi zinthu zosiyanasiyana zachilengedwe. Zinthuzi zimathandiza kuti igwiritsidwe ntchito pochita zinthu zopopera kuti isinthe zinthu zomwe ma polima amatuluka. Ntchito Kusintha kwa Polima: TFEMA imagwiritsidwa ntchito makamaka ngati monomer popanga ma polima apadera ndi ma copolymer. Kuphatikizidwa kwake mu unyolo wa polima kumapereka magawo opangidwa ndi fluorinated omwe amawonjezera kukana kwa mankhwala, kulimba, ndi mphamvu zomatira. Ntchito zimaphatikizapo zokutira, zomatira, ndi zinthu zomwe zimafuna kugwira ntchito bwino kwambiri pansi pa mikhalidwe yovuta. Kusintha kwa Malo: Kusakonda madzi kwa TFEMA kumapangitsa kuti ikhale yabwino kwambiri posintha malo kuti ichotse madzi ndi zinthu zina za polar. Katunduyu amagwiritsidwa ntchito popaka pamwamba pa zamagetsi, zida zamankhwala, ndi zinthu zomangamanga komwe kumafunika kukana madzi ndi kuyeretsa kosavuta. Kugwiritsa Ntchito Zomatira: Kuthekera kwa TFEMA kukulitsa mphamvu yomatira ndi kulimba kumapangitsa kuti ikhale yothandiza popanga zomatira za substrates zomatira zomwe nthawi zambiri zimakhala zovuta kumamatira, monga ma polima ndi zitsulo zosungunuka. Kupanga TFEMA kumapangidwa kudzera mu esterification ya methacrylic acid ndi 2,2,2-trifluoroethanol. Zomwe zimachitika nthawi zambiri zimayambitsidwa ndi asidi, zomwe zimapangitsa TFEMA kukhala chinthu cha ester pamodzi ndi madzi. Njira zoyeretsera zimaphatikizapo kusungunuka kapena kuchotsa zosungunulira kuti TFEMA ikhale yoyera kwambiri yoyenera kugwiritsidwa ntchito m'mafakitale. Kusavuta kwa polymerization kwa mankhwalawa kumawonjezeranso ntchito yake popanga zipangizo zopangidwa mwamakonda zomwe zimagwirizana ndi zofunikira zinazake zogwirira ntchito. Mwachidule, 2,2,2-trifluoroethyl methacrylate ndi chinthu chamtengo wapatali mu polymer chemistry ndi sayansi ya zinthu, zomwe zimapereka zinthu zapadera zomwe zimathandiza pakupanga zipangizo zapamwamba zokhala ndi kulimba komanso magwiridwe antchito abwino. Kusinthasintha kwake pakusintha pamwamba ndi kupanga zomatira kukuwonetsa kufunika kwake m'magawo osiyanasiyana amafakitale, kuthandizira kupita patsogolo kwa ukadaulo ndi kupanga zinthu zatsopano.
