Acetic acid (tseem hu ua acetic acid, glacial acetic acid, los yog cov mis CH COOH) yog cov organic mono acid uas ₃ yog lub hauv paus ntawm acidity thiab pungent tsw nyob rau hauv vinegar. Ntshiab anhydrous acetic acid (glacial acetic acid) yog cov kua tsis muaj xim hygroscopic nrog qhov chaw khov ntawm 16.7 ° C (62 ° F) thiab dhau los ua cov xim tsis muaj xim thaum khov. Txawm hais tias acetic acid yog cov kua qaub tsis muaj zog raws li nws lub peev xwm los cuam tshuam rau hauv cov tshuaj aqueous, acetic acid yog corrosive thiab nws cov vapors ua rau khaus qhov muag thiab qhov ntswg.
acetic acid, saturated carboxylic acid uas muaj ob lub atoms, yog ib qho tseem ceeb oxy-muaj derivative ntawm hydrocarbons. Molecular formula C2H4O₂, qauv Molecular qauv
Molecular qauv
Qhov luv CH₃COOH, HAC yog daim ntawv luv. Cov pab pawg ua haujlwm ntawm cov qauv qauv yog pawg carboxyl thiab CAS tus lej yog 64-19-7. Vim yog lub ntsiab ntawm vinegar, tseem hu ua acetic acid. Hauv cov txiv hmab txiv ntoo lossis zaub roj, piv txwv li, feem ntau yog nyob rau hauv daim ntawv ntawm esters ntawm lawv cov tebchaw; Nws muaj nyob hauv cov kua qaub dawb hauv cov ntaub so ntswg, quav, thiab cov ntshav ntawm cov tsiaj. Ordinary vinegar muaj 3% mus rau 5% acetic acid. Acetic acid yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw ntxhiab tsw. Tus txheeb ze molecular hnyav yog 60.05, lub melting point yog 16.6 ℃, lub boiling point yog 117.9 ℃, tus txheeb ze ceev yog 1.0492 (20/4 ℃), qhov ceev yog siab tshaj li dej, lub refractive index yog 1.3716. Ntshiab acetic acid tuaj yeem tsim cov dej khov zoo li hauv qab 16.6 ° C, yog li nws feem ntau hu ua glacial acetic acid. Soluble hauv dej, ethanol, ether thiab carbon tetrachloride. Thaum cov dej ntxiv rau acetic acid, tag nrho cov ntim tau me dua thiab qhov ceev nce mus txog thaum qhov sib piv molecular yog 1: 1, sib haum rau kev tsim ntawm mono-acid CH3C (OH) ₃, uas yog ntxiv diluted thiab tsis hloov pauv hauv ntim. .
