Isicelo
Kuyi-asidi ephilayo eyaziwayo enamandla kakhulu futhi iyithuluzi lokwenziwa elinemisebenzi eminingi.Ngokubola okuqinile kanye ne-hygroscopicity, isetshenziswa kabanzi ezimbonini zemithi namakhemikhali, njengama-nucleosides, ama-antibiotics, ama-steroids, amaprotheni, ama-saccharides, amavithamini synthesis, ukuguqulwa kwenjoloba ye-silicone, njll. Ngomthamo omncane, i-asidi eqinile kanye nezakhiwo ezizinzile, ingathatha indawo. ama-asidi endabuko e-inorganic afana ne-sulfuric acid ne-hydrochloric acid ezikhathini eziningi futhi abamba iqhaza ekwandiseni nasekuthuthukiseni inqubo.Ingasetshenziswa futhi njenge-catalyst ye-isomerization kanye ne-alkylation ukulungiselela i-2,3-dihydro-2-idenone ne-1-tetralone, kanye nokukhipha i-glycoside ku-glycoprotein.
Izinyathelo Zokuphepha
I-Trifluoromethanesulfonic acid ingenye ye-organic acid enamandla kakhulu.Ukuthintana namehlo kuzodala ukusha okukhulu kwamehlo kanye nobumpumputhe okungenzeka.Ukuthinta isikhumba kuzodala ukushiswa kwamakhemikhali okunamandla, kanye nokubambezeleka kokulimala kwezicubu ezinzima.Ukuhogela umhwamuko kungabangela ukudlikizeka okukhulu, ukuvuvukala, kanye ne-edema.Ukungenisa kungabangela ukusha okukhulu kwamathumbu.Ngakho-ke, ngisho namanani amancane adinga izinto zokuvikela ezifanele (njengezibuko, amagilavu amelana ne-asidi ne-alkali, kanye nemaski yegesi), kanye nomoya omuhle.
Ukwengezwa kwe-trifluoromethanesulfonic acid kuzincibilikisi ze-polar kubangela ukuphuma kwe-exotherm ngenxa yokuhlakazeka.Le exotherm enamandla ifana nomphumela wokuncibilikisa i-sulfuric acid emanzini.Kodwa-ke, ukuyincibilikisa ku-solvent ye-polar kuyingozi ngokwemvelo kunokuncibilikisa i-sulfuric acid emanzini.I-exotherm enamandla ingase ibangele ukuba isincibilikisi sihwamuke noma siqhume.Ngakho-ke, ukuncibilika kwenani elikhulu le-trifluoromethanesulfonic acid kuma-organic solvents kufanele kugwenywe.Uma kudingekile ukwenza kanjalo, qiniseka ukuthi ulawula ukushesha kokwehla futhi uqinisekise ukunyakazisa okwanele, ukungena komoya okuhle, kanye nezisetshenziswa zokushintshisana okungenzeka zokupholisa ukuze ukhiphe ukushisa okuningi okukhiqizwa ngangokunokwenzeka.
