Trifluoroacetic acid yog ib qho tseem ceeb fatty fluorine-muaj nruab nrab. Vim yog cov qauv tshwj xeeb ntawm trifluoromethyl, nws cov khoom sib txawv ntawm lwm yam cawv. Nws tuaj yeem koom nrog ntau yam kev cuam tshuam ntawm cov organic synthesis, tshwj xeeb tshaj yog nyob rau hauv cov synthesis ntawm fluorine-muaj tshuaj, tshuaj tua kab thiab dyes.
[Chemical Properties]
Muaj zog acidity: Tus nqi pKa ntawm trifluoroacetic acid yog 0.23, qhia tias nws yog ib tug muaj zog acid, ib puas txhiab npaug zog dua acetic acid.
Kev ruaj ntseg: ruaj khov siab dua 205 degree, ester thiab amide derivatives tau yooj yim hydrolyzed. Tsis sib haum nrog cov khoom siv hluav taws xob, cov hauv paus muaj zog, dej, thiab muaj zog oxidants. Tsis-flammable. Hygroscopic. Tej zaum yuav hnov mob hnyav nrog alkali.
Kev txo qis: tuaj yeem txo qis rau trifluoroacetaldehyde thiab trifluoroethanol los ntawm sodium borohydride lossis lithium aluminium hydride.
Lub cev qhuav dej: Yooj yim lub cev qhuav dej rau trifluoroacetic anhydride nyob rau hauv kev ua ntawm phosphorus pentoxide.
Solubility: Nws muaj peev xwm yaj ib feem ntawm carbon disulfide thiab alkanes nrog ntau tshaj li rau carbon atoms, thiab yog ib qho hnyav hnyav rau cov proteins thiab polyesters.
Volatility: Trifluoroacetic acid yog ib yam khoom tsis haum thiab yuav tsum tau muab kaw tom qab kev npaj los tiv thaiv volatilization.
[Daim ntawv thov]
