Qhov sib txawv tseem ceeb ntawm oxalic acid thiab acetic acid yog tias oxalic acid muaj ob lub chaw carbonyl carbon, whereas acetic acid muaj ib qhov chaw carbonyl carbon.
Oxalic acid thiab acetic acid yog cov organic tebchaw uas muaj carbon, hydrogen thiab oxygen atoms hauv lawv cov molecules. Ob lub tebchaw acidic no muaj qee qhov zoo sib xws vim muaj cov chaw carbonyl carbon.
Oxalic Acid yog dab tsi?
Oxalic acid yog cov organic compound uas muaj cov tshuaj formula H2C2O4. Cov tshuaj no tshwm sim raws li cov khoom tsis muaj xim uas yooj yim yaj hauv dej. Oxalic acid yog dicarboxylic acid vim nws yog kev sib xyaw ntawm ob pawg carboxylic acid; Qhov tseeb, nws yog qhov yooj yim tshaj plaws dicarboxylic acid. Tsis tas li ntawd, nws muaj lub zog acid siab thiab muaj zog txo tus neeg sawv cev. Lub hauv paus conjugate ntawm cov kua qaub no yog oxalate ion. Feem ntau, oxalic acid tshwm sim hauv daim ntawv dihydrate. Ntxiv mus, nws ib txwm tshwm sim hauv qee yam khoom noj. Cov molar loj ntawm daim ntawv anhydrous yog 90 g / mol.
Daim duab 01: Cov qauv ntawm Oxalic Acid
Peb tuaj yeem npaj oxalic acid los ntawm oxidation ntawm carbohydrates lossis qabzib siv nitric acid lossis cua nyob rau hauv lub xub ntiag ntawm vanadium pentoxide. Muaj ob lub polymorphs ntawm oxalic acid qhov twg ib tug polymorphic qauv muaj ib tug saw-zoo li cov qauv vim muaj cov hydrogen bonds thaum lwm yam polymorphic qauv nyob rau hauv daim ntawv-zoo li cov qauv.
Thaum xav txog kev siv cov oxalic acid, nws yog qhov tseem ceeb hauv kev tu thiab tshuaj dawb huv, ua cov tshuaj reagent hauv extractive metallurgy, pab tau hauv cov txheej txheem txhuas anodizing, thiab lwm yam.
YAcetic Acid yog dab tsi?
Acetic acid yog cov organic compound uas muaj cov tshuaj formula CH3COOH. Nws yog qhov yooj yim thib ob carboxylic acid. Cov kua qaub no tshwm sim raws li cov kua tsis muaj xim uas muaj pungent, vinegar zoo li tsw. Tsis tas li ntawd, acetic acid muaj qhov txawv qaub saj thiab. Cov tshuaj no muaj ib pawg methyl txuas nrog carboxylic acid. Nws yog ib tug tsis muaj zog acid vim nws dissociates ib feem nyob rau hauv ib tug aqueous tov. Cov molar loj ntawm acetic acid yog 60.05 g / mol. Lub hauv paus conjugate ntawm cov kua qaub no yog acetate ion. Ntxiv mus, lub systemic IUPAC lub npe ntawm acetic acid yog ethanoic acid.
Daim duab 02: Cov qauv ntawm Acetic Acid
Nyob hauv nws daim ntawv, acetic acid form chains los ntawm interconnecting cov molecules los ntawm hydrogen bonds. Nyob rau hauv nws vapor theem, muaj dimers ntawm acetic acid. Tsis tas li ntawd, hauv nws lub xeev ua kua, nws yog hydrophilic protic hnyav. Ntxiv mus, ntawm physiological pH tej yam kev mob, cov compound no muaj nyob rau hauv ib tug tag nrho ionized daim ntawv li acetate. Peb tuaj yeem tsim cov acetic acid hauv ob qho tib si hluavtaws thiab cov kab mob fermentation. Ntxiv rau cov no, nyob rau hauv txoj kev hluavtaws, acetic acid yog tsim los ntawm methanol carbonylation.
Peb tuaj yeem tsim cov acetic acid hauv kev lag luam hluavtaws lossis los ntawm kev lom neeg. Piv txwv li, peb tuaj yeem tsim cov acetic acid los ntawm carbonylation ntawm methanol, thiab peb tuaj yeem tsim cov kua qaub no los ntawm fermentation ntawm cov noob xws li kua cider, siv qos yaj ywm, mov, thiab lwm yam.
Qhov txawv ntawm Oxalic Acid thiab Acetic Acid yog dab tsi?
Oxalic acid thiab acetic acid yog ob hom carboxylic acid compounds. Qhov sib txawv tseem ceeb ntawm oxalic acid thiab acetic acid yog oxalic acid muaj ob lub chaw carbonyl carbonyl thaum acetic acid muaj ib lub chaw carbonyl carbon. Yog li, oxalic acid yog dicarboxylic acid whereas acetic acid yog monocarboxylic acid.
Ntxiv mus, oxalic acid yog tsim los ntawm oxidation ntawm carbohydrates los yog qabzib siv nitric acid los yog cua nyob rau hauv lub xub ntiag ntawm vanadium pentoxide thaum acetic acid yog tsim los ntawm ob qho tib si hluavtaws thiab cov kab mob fermentation.
Hauv qab infographic nthuav tawm ntau cov ntsiab lus ntawm qhov sib txawv ntawm oxalic acid thiab acetic acid.
Summary – Oxalic Acid vs Acetic Acid
Oxalic acid thiab acetic acid yog ob hom carboxylic acid compounds. Qhov sib txawv tseem ceeb ntawm oxalic acid thiab acetic acid yog tias oxalic acid muaj ob lub chaw carbonyl carbonyl hos acetic acid muaj ib lub chaw carbonyl carbon.
