Glacial acetic acid (CAS 64-19-7) yog siv dav hauv kev lag luam tshuaj thiab tshuaj lom neeg nruab nrab hauv cov haujlwm xws li txheej txheej, nplaum nplaum, ua cov roj hmab, tshuaj synthesis, textile dyeing, thiab ua zaub mov (E260 thaum zaub mov qib). Nws tus nqi sib txawv ntawm thaj tsam, qib purity, khoom siv thiab kev thov, thiab ntim loj (nruab ntau vs nruas).
Cov khoom ntawm Acetic Acid (GAA CAS 64-19-7)
Lub cev muaj zog
- Xeev thiab tshwm sim:Acetic Acid (CH₃COOH)tshwm sim raws li ib tug tsis muaj kob, pob tshab kua ntawm tus qauv kub thiab siab, emitting ib tug muaj zog pungent tsw (ie, vinegar tsw) thiab exhibiting siab volatility.
- Solubility: Infinitely miscible nrog polar solvents xws li dej, ethanol, thiab diethyl ether. Cov cuab yeej no ua rau nws siv dav hauv kev daws teeb meem -raws li kev siv.
- Boiling Point thiab Melting Point: Boils ntawm kwv yees li 117.9℃(247.8℃F) thiab melts ntawm kwv yees li 16.6℃(32.3℃F). Thaum lub caij ntuj no txias txias, ntshiab acetic acid crystallizes rau hauv dej khov -zoo li khoom, yog li nws lwm lub npe "glacial acetic acid."
- Corrosivity: pom tsis muaj zog acidity. Thaum muaj ntau dua (piv txwv li, glacial acetic acid), nws tuaj yeem ua rau cov tawv nqaij, qhov muag, thiab cov mucous membranes. Tam sim ntawd yaug nrog dej thaum sib cuag.
Chemical Properties
- Acidity: Muab faib ua cov kua qaub tsis muaj zog, nws ib nrab ionizes hauv dej kom tso H⁺ (ionization sib npaug: CH₃COOH ⇌ CH₃COO⁻ + H⁺). Nws reacts nrog bases (piv txwv li, NaOH) thiab carbonates (piv txwv li, Na₂CO₃) los tsim cov ntsev thiab dej. Piv txwv li, reacting nrog baking soda ua rau cov pa roj carbon dioxide (feem ntau siv rau descaling).
- Esterification Reaction: Nyob rau hauv cov xwm txheej ntawm cua sov thiab catalysis los ntawm concentrated sulfuric acid, nws reacts nrog cawv (xws li, ethanol) los tsim esters (xws li, ethyl acetate) thiab dej. Cov tshuaj tiv thaiv no yog ib qho tseem ceeb hauv kev tsim cov tshuaj tsw qab thiab cov kuab tshuaj.
- Stability: Acetic Acid (GAA) ruaj khov ntawm chav tsev kub thiab tsis yooj yim decompose. Txawm li cas los xij, nyob rau hauv qhov kub thiab txias los yog muaj cov oxidizing muaj zog, nws tuaj yeem oxidized rau carbon dioxide thiab dej.
