Daim ntawv thov
Nws yog lub zog tshaj paub cov organic acid thiab ntau yam khoom siv hluavtaws.Nrog muaj zog corrosivity thiab hygroscopicity, nws yog dav siv nyob rau hauv kev lag luam tshuaj thiab tshuaj, xws li nucleosides, tshuaj tua kab mob, steroids, protein, saccharides, vitamin synthesis, silicone roj hmab hloov, thiab lwm yam. Nrog rau me me npaum li cas, muaj zog acidity thiab ruaj khov zog, nws muaj peev xwm hloov. tsoos inorganic acids xws li sulfuric acid thiab hydrochloric acid nyob rau hauv ntau zaus thiab ua si lub luag hauj lwm nyob rau hauv optimizing thiab txhim kho cov txheej txheem.Nws tseem tuaj yeem siv los ua cov khoom siv rau isomerization thiab alkylation los npaj 2,3-dihydro-2-indenone thiab 1-tetralone, thiab tshem tawm glycoside ntawm glycoprotein.

Kev Tiv Thaiv Kev Nyab Xeeb
Trifluoromethanesulfonic acid yog ib qho ntawm cov organic acids uas muaj zog tshaj plaws.Kev sib cuag nrog lub qhov muag yuav ua rau qhov muag kub hnyiab thiab ua rau qhov muag tsis pom.Kev sib cuag nrog daim tawv nqaij yuav ua rau mob hnyav heev, nrog rau kev ncua ntev ntawm cov ntaub so ntswg loj.Kev nqus pa ntawm vapors tuaj yeem ua rau muaj kev cuam tshuam loj heev, o, thiab edema.Kev noj haus tuaj yeem ua rau mob plab hnyuv loj.Yog li ntawd, txawm tias me me yuav tsum muaj cov cuab yeej tiv thaiv kom zoo (xws li tsom iav, kua qaub thiab alkali resistant hnab looj tes, thiab lub npog ntsej muag roj), thiab qhov cua zoo.
Qhov sib ntxiv ntawm trifluoromethanesulfonic acid rau polar solvents tshwm sim nyob rau hauv exotherm vim dissolution.Qhov khaus exotherm no zoo ib yam li cov nyhuv ntawm cov kua qaub sulfuric hauv dej.Txawm li cas los xij, dissolving nws nyob rau hauv ib tug polar solvent inherently txaus ntshai tshaj dissolving sulfuric acid nyob rau hauv dej.Lub exotherm muaj zog tuaj yeem ua rau cov kuab tshuaj evaporate lossis txawm tawg.Yog li ntawd, dissolving ntau ntawm trifluoromethanesulfonic acid nyob rau hauv cov organic solvents yuav tsum tau zam.Thaum nws tsim nyog ua li ntawd, nco ntsoov tswj qhov kev poob qis thiab xyuas kom muaj kev sib xyaw kom txaus, qhov cua zoo, thiab tejzaum nws cov khoom siv txias txias kom tshem tawm cov cua sov ntau li ntau tau.
