Application
Ndiyo yakasimba kwazvo inozivikanwa organic acid uye inoshanda zvakasiyana-siyana yekugadzira chishandiso.Iine corrosivity yakasimba uye hygroscopicity, inoshandiswa zvakanyanya mumaindasitiri emishonga nemakemikari, akadai senyucleosides, antibiotics, steroids, protein, saccharides, vitamin synthesis, silicone rubber modification, etc. Iine diki dosage, yakasimba acidity uye yakagadzikana zvinhu, inogona kutsiva. echinyakare inorganic acids senge sulfuric acid uye hydrochloric acid mune dzakawanda nguva uye anoita basa mukugadzirisa nekuvandudza maitiro.Inogonawo kushandiswa sechinhu chinokonzera isomerization uye alkylation kugadzirira 2,3-dihydro-2-idenone uye 1-tetralone, uye kubvisa glycoside kubva kuglycoprotein.
Chengetedzo Yekuchengetedza
Trifluoromethanesulfonic acid imwe yeakanyanya simba organic acids.Kubata maziso kunokonzera kupisa kwakanyanya kwemaziso uye hunogona kuita upofu.Kubata neganda kunokonzera kupisa kwakanyanya kwekemikari, pamwe nekunonoka kwekukuvara kwenyama.Kufema mweya wemhute kunogona kukonzera kugwinha kwakanyanya, kuzvimba, uye edema.Kudya kunogona kukonzera kupisa kwakanyanya kwegastrointestinal.Naizvozvo, kunyangwe zvidiki zvinoda midziyo yekudzivirira yakakodzera (senge magirovhosi, acid uye alkali resistant gloves, uye gasi mask), uye mhepo yakanaka.
Kuwedzerwa kwe trifluoromethanesulfonic acid kune polar solvents kunoguma ne exotherm nekuda kwekuparara.Iyi exotherm yakasimba yakafanana nemhedzisiro yekunyungudutsa sulfuric acid mumvura.Nekudaro, kuinyungudutsa mu polar solvent kune njodzi zvakanyanya pane kunyungudutsa sulfuric acid mumvura.Iyo exotherm yakasimba inogona kuita kuti solvent inyunguduke kana kuputika.Naizvozvo, kunyungudutsa yakawanda ye trifluoromethanesulfonic acid mu organic solvents kunofanirwa kudzivirirwa.Pazvinenge zvakakodzera kuita kudaro, iva nechokwadi chekudzora kukwidziridzwa kwekudonha uye kuve nechokwadi chekukurudzira kwakaringana, kufefetera kwakanaka, uye pamwe nekutonhodza midziyo yekutsinhana kuti ubvise kupisa kwakawanda kunogadzirwa sezvinobvira.
