Imikhiqizo

I-2,2,2-Trifluoroethyl formate, eyaziwa nangokuthi i-trifluoroacetic acid ethyl ester, iyinhlanganisela ye-organic enefomula yamakhemikhali C4H5F3O2.Iwuketshezi olungenambala olunephunga elimnandi futhi ithola izinhlelo zokusebenza eziningana ezimbonini ezahlukene ngenxa yezindawo zayo eziyingqayizivele.Okunye ukusetshenziswa okuyinhloko kwe-2,2,2-trifluoroethyl formate injenge-solvent ekuphenduleni kwamakhemikhali okuhlukahlukene.Kuyinhlanganisela ye-polar kakhulu engancibilikisa izinhlobonhlobo zezinto eziphilayo kanye ne-inorganic, iyenze ibe yigugu ezinqubweni ezinjengokukhipha, ukuhlanzwa, kanye nokuhlanganiswa.Ikhono layo lokuncibilikisa kokubili inhlanganisela ye-polar kanye ne-non-polar yenza kube usizo ikakhulukazi ezimbonini zemithi, agrochemical, kanye namakhemikhali amahle.Ukwengeza, i-2,2,2-trifluoroethyl formate isetshenziswa njenge-reagent ku-organic synthesis.Isebenza njengomthombo we-trifluoroethyl cation, engabhekana nokusabela okuhlukahlukene ukwethula iqembu le-trifluoroethyl libe ngama-molecule ephilayo.Isibonelo, ingasetshenziswa ekulungiseleleni ama-intermediate emithi, lapho ukwethulwa kweqembu le-trifluoroethyl kungathuthukisa umsebenzi wezinto eziphilayo noma kuthuthukise izakhiwo ze-pharmacological zezinhlanganisela ezihlosiwe.Okunye ukusetshenziswa kwe-formate ye-2,2,2-trifluoroethyl ku- umkhakha we-analytical chemistry.Ivame ukusetshenziswa njenge-ejenti ephumayo ekuhlaziyeni izinhlanganisela eziqukethe ama-athomu e-hydrogen asebenzayo.Ngokusabela ngalezi zinhlanganisela, yakha okuphuma kokunye okuzinzile okungatholwa kalula futhi kukalwe kusetshenziswa amasu afana ne-gas chromatography noma i-chromatography ewuketshezi ehlanganiswe ne-mass spectrometry.Le nqubo yokukhishwa kwe-derivatization ithuthukisa ukuzwela nokukhetha kokuhlaziywa, okuvumela ukuhlonza okunembe kakhudlwana kanye nokulinganisa izinhlanganisela ezihlosiwe.Ngaphezu kwalokho, i-2,2,2-trifluoroethyl formate isetshenziswa ekukhiqizeni ama-fluorinated compounds.Iqembu le-trifluoroethyl elikhona ku-molecule lingabhekana nokusabela okuhlukahlukene ukuze kuhlanganiswe amakhemikhali e-fluoro akhethekile, njengama-surfactants, izinto zokuthambisa, nezinto ezinezakhiwo ezihlukile ezishisayo nezikagesi.Lezi zinhlanganisela zithola izinhlelo zokusebenza ezimbonini ezifana ne-electronics, i-aerospace, nezimoto, lapho izici zazo ezithile zifunwa kakhulu.Kodwa-ke, kubalulekile ukuqaphela ukuthi i-2,2,2-trifluoroethyl formate kufanele iphathwe ngokuqapha njengoba iyinto eyingozi. .Ivutha kakhulu, iyingozi uma igwinywe noma ihoxiswa, futhi ingabangela ukucasuka esikhumbeni nasemasweni.Izinyathelo zokuphepha ezifanele, ezinjengokugqoka izinto zokuzivikela nokusebenza endaweni enomoya omuhle, kufanele zilandelwe ukuze kuncishiswe izingozi phakathi nokusetshenziswa kwayo. i-reagent, i-ejenti ephuma kuyo, kanye nesakhiwo sokwakha ezimbonini ezihlukahlukene.Ikhono layo lokuncibilikisa izinhlobonhlobo zezinhlanganisela, ukwethula iqembu le-trifluoroethyl, nokuthuthukisa izinqubo zokuhlaziya kuyenza ibe yigugu emikhakheni yezemithi, ye-agrochemical, analytical, kanye ne-fluorine chemistry.Kodwa-ke, ngenxa yemvelo yayo eyingozi, izinyathelo ezifanele zokuphepha kufanele zithathwe lapho kusingathwa lesi sithako.
