Qhov sib txawv tseem ceeb ntawm trichloroacetic acid thiab trifluoroacetic acid yog tias trichloroacetic acid yog cov xim tsis muaj xim rau dawb crystalline khoom sib xyaw, qhov trifluoroacetic acid tshwm sim ua kua tsis muaj xim.
Trichloroacetic acid thiab trifluoroacetic acid yog cov organic acid tebchaw peb tuaj yeem categorize li carboxylic acids vim muaj -COOH functional group.
YTrichloroacetic Acid yog dab tsi?
Trichloroacetic acid yog cov organic compound uas muaj cov tshuaj formula (Cl)3-C-C-OOH. Nws tseem muaj npe hu ua TCA acid, TCAA, los yog trichloroethanoic acid. Nws yog ib qho analogue ntawm acetic acid; Peb lub hydrogen atoms sib txuas ncaj qha rau cov pa roj carbon atom hauv acetic acid yog hloov los ntawm peb lub chlorine atoms hauv trichloroacetic acid molecule. Muaj cov ntsev thiab esters ntawm trichloroacetic acid uas tau sau npe ua trichloroacetates.
Daim duab 01: Cov qauv tshuaj ntawm Trichloroacetic Acid
Tsis tas li ntawd, cov tshuaj no tshwm sim ua cov xim tsis muaj xim rau dawb crystalline khoom sib xyaw. Nws kuj muaj ib tug ntse, pungent tsw. Peb tuaj yeem npaj cov tshuaj no los ntawm cov tshuaj tiv thaiv ntawm cov tshuaj chlorine thiab acetic acid nyob rau hauv lub xub ntiag ntawm ib tug haum catalyst. Ntxiv rau qhov no, peb tuaj yeem tsim cov khoom siv tib yam los ntawm oxidation ntawm trichloroacetaldehyde.
Muaj ntau qhov kev siv ntawm trichloroacetic acid, suav nrog kev siv biochemistry rau nag lossis daus ntawm macromolecules (xws li DNA, RNA, thiab cov proteins), siv rau hauv kev kho kom zoo nkauj xws li tshuaj tev, ua tshuaj pleev xim rau chemoablation ntawm warts, etc.
YTrifluoroacetic Acid yog dab tsi?
Trifluoroacetic acid yog cov organic compound uas muaj cov tshuaj formula (F)3-C-C-OOH. Nws yog ib qho organofluorine compound thiab yog ib qho piv txwv ntawm acetic acid uas muaj tag nrho peb cov hydrogen atoms hauv pawg acetyl hloov nrog fluorine atoms.
Daim duab 02: Cov qauv tshuaj ntawm Trifluoroacetic Acid
Ntxiv mus, cov tshuaj no tshwm sim raws li cov kua tsis muaj xim muaj pungent, vinegar zoo li tsw. Nws yog miscible nrog dej. Thaum xav txog lub zog acidic, trifluoroacetic acid yog cov kua qaub uas muaj zog dua li acetic acid vim qhov siab electronegativity ntawm fluorine atoms thiab qhov tshwm sim ntawm electron rho tawm ntawm pawg trifluoromethyl, uas tsis muaj zog ntawm cov pa oxygen-hydrogen bond.
Industrially, peb tuaj yeem npaj trifluoroacetic acid los ntawm electrofluorination ntawm acetyl chloride los yog acetic anhydride ua raws li hydrolysis ntawm cov khoom tshwm sim. Txawm li cas los xij, qhov sib xyaw no kuj tshwm sim nyob rau hauv dej hiav txwv tab sis nyob rau hauv cov kab ke.
Muaj qee qhov kev siv tseem ceeb ntawm trifluoroacetic acid. Nws yog qhov ua ntej rau ntau lwm cov tshuaj fluorinated xws li trifluoroacetic anhydride. Nws kuj tseem muaj txiaj ntsig zoo li cov tshuaj reagent hauv cov organic synthesis vim nws cov khoom xws li volatility, solubility hauv cov kuab tshuaj organic, acidic zog, thiab lwm yam. Txawm li cas los xij, cov khoom no yog corrosive vim acidity siab thiab muaj teeb meem thaum nqus tau.
Qhov txawv ntawm Trichloroacetic Acid thiab Trifluoroacetic Acid yog dab tsi?
Trichloroacetic acid thiab trifluoroacetic acid yog cov organic acid tebchaw peb tuaj yeem categorize li carboxylic acids vim muaj -COOH ua haujlwm pab pawg. Qhov sib txawv tseem ceeb ntawm trichloroacetic acid thiab trifluoroacetic acid yog tias trichloroacetic acid yog cov xim tsis muaj xim rau dawb crystalline khoom, thaum trifluoroacetic acid tshwm sim ua kua tsis muaj xim. Ntxiv mus, trichloroacetic yog tsim los ntawm chlorine, carbon, oxygen thiab hydrogen atoms thaum trifluoroacetic yog tsim los ntawm fluorine, carbon, oxygen thiab hydrogen atoms.
Cov hauv qab no qhia txog qhov sib txawv ntawm trichloroacetic acid thiab trifluoroacetic acid nyob rau hauv tabular rau ib sab ntawm kev sib piv.
Summary – Trichloroacetic Acid vs Trifluoroacetic Acid
Trichloroacetic acid yog cov organic compound uas muaj cov tshuaj formula (Cl)3-C-C-OOH, thaum trifluoroacetic acid yog cov organic compound uas muaj cov tshuaj formula (F) 3-C-C-OOH. Qhov sib txawv tseem ceeb ntawm trichloroacetic acid thiab trifluoroacetic acid yog tias trichloroacetic acid yog cov xim tsis muaj xim rau dawb crystalline khoom, thaum trifluoroacetic acid tshwm sim ua kua tsis muaj xim.
