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

I-2,2,2-Trifluoroethyl methacrylate (TFEMA) iyinhlanganisela eguquguqukayo enezakhiwo zamakhemikhali ezihlukile ezenza ibe yigugu ezisetshenziswayo ezimbonini ezahlukahlukene. Izakhiwo I-TFEMA ibonakala ngesakhiwo sayo samakhemikhali, esihlanganisa iqembu le-trifluoromethyl (-CF3) elinamathele kumgogodla we-ethyl methacrylate. Lokhu kuhlelwa kwama-molecule kunikeza i-TFEMA izakhiwo ezihlukile njengamandla aphansi omhlaba kanye nokungangeni kwamanzi amaningi, okwenza ifaneleke ekusetshenzisweni okudinga izinto ezinokumelana kwamakhemikhali nokwemvelo okuthuthukisiwe. I-TFEMA iwuketshezi olucacile, olungenambala olunephuzu lokubila elingaba ngu-100°C futhi luxutshwa nezinhlobo ezahlukene zezixazululo eziphilayo. Lezi zici zivumela ukusetshenziswa kwayo ekuphenduleni kwe-polymerization ukuguqula izakhiwo zama-polymer aphumayo. Ukusetshenziswa Ukuguqulwa kwe-Polymer: I-TFEMA isetshenziswa kakhulu njenge-monomer ekuhlanganisweni kwama-polymer akhethekile nama-copolymer. Ukufakwa kwayo kumaketanga e-polymer kunikeza izingxenye ze-fluorinated ezithuthukisa ukumelana kwamakhemikhali, ukuqina, kanye nezakhiwo zokunamathela. Izicelo zifaka phakathi ukumbozwa, izinamathiselo, nezinto ezidinga ukusebenza okuphezulu ngaphansi kwezimo ezinzima. Ukuguqulwa Komphezulu: Imvelo ye-TFEMA yokungathandi amanzi iyenza ibe yindawo ekahle yokushintsha izindawo ukuze ixoshe amanzi nezinye izinto ezimazombezombe. Lesi sici sithola ukusetshenziswa ekumbozweni komphezulu kwezinto zikagesi, amadivayisi ezokwelapha, kanye nezinto zokwakha lapho kudingeka khona ukumelana namanzi kanye nokuhlanza okulula. Izicelo Zokunamathela: Ikhono le-TFEMA lokuthuthukisa amandla okunamathela kanye nokuqina liyenza ibe usizo ekwakheni izinamathiselo zezingxenye zokubopha ezivame ukuba nzima ukuzibopha, njenge-polymers ene-fluorine kanye nezinsimbi. Ukwenziwa kwe-TFEMA kwenziwa ngokwenziwa kwe-ester ye-methacrylic acid nge-2,2,2-trifluoroethanol. Ukusabela kuvame ukuqhutshwa yi-asidi, okuveza i-TFEMA njengomkhiqizo we-ester kanye namanzi. Izindlela zokuhlanza zifaka phakathi ukuhluzwa noma ukukhipha i-solvent ukuze kutholakale i-TFEMA ngobumsulwa obukhulu obufanele ukusetshenziswa kwezimboni. Ukulula kwe-polymerization kwe-compound kuthuthukisa kakhulu ukusetshenziswa kwayo ekudaleni izinto ezenziwe ngokwezifiso ezifanela izidingo ezithile zokusebenza. Ngamafuphi, i-2,2,2-trifluoroethyl methacrylate iyinhlanganisela ebalulekile kumakhemikhali e-polymer kanye nesayensi yezinto, enikeza izakhiwo ezihlukile ezifaka isandla ekuthuthukisweni kwezinto ezithuthukisiwe ezinokuqina okuthuthukisiwe kanye nezici zokusebenza. Ukuguquguquka kwayo ekuguqulweni kwendawo kanye nokwakheka kwe-glue kugcizelela ukubaluleka kwayo emikhakheni ehlukahlukene yezimboni, kusekela intuthuko kwezobuchwepheshe kanye nokusungula izinto ezintsha.
