Acetic acid kua (CAS 64-19-7)yog tsim thiab muab nyob rau hauv ntau qib purity, ua rau nws haum rau ntau yam kev lag luam, kuaj, thiab zaub mov- hais txog daim ntawv thov.
Cov qib purity ntau ntawm acetic acid kua (CAS: 64-19-7)
Acetic acid purity feem ntau yog qhia raws li qhov feem pua ntawm qhov hnyav (wt%). Cov kev lag luam purities feem ntau yog los ntawm cov tshuaj diluted (30-80%) mus rau siab -purity glacial acetic acid (Ntau dua lossis sib npaug li 99%).
| Purity / Qib | Hom Specification | Cov ntawv thov tseem ceeb |
|---|---|---|
| 99.5–99.9% | Glacial acetic acid (GAA), dej tsawg dua lossis sib npaug li 0.5% | Chemical synthesis, tshuaj, coatings, adhesives, roj hmab ua |
| 99.0% | Industrial / Laboratory qib | Kev siv dav dav, cov kuab tshuaj, cov khoom nruab nrab |
| 80–75% | Concentrated aqueous acetic acid | Roj hmab latex coagulation, textile dyeing, pH hloov, dej kho |
| 60–50% | Diluted acetic acid daws | Muaj kev tu, descaling, txheej txheem pH tswj |
| Qib zaub mov (Ntau dua lossis sib npaug li 99% lossis diluted) | Ua tau raws li cov qauv khoom noj ntxiv (E260) | Khoom noj khoom haus ua, vinegar ntau lawm, preservation |
| Laboratory qib | High purity nrog tswj impurities | Kev ntsuas ntsuas, R & D lub chaw soj nstuam |
Cov khoom ntawm Acetic Acid (GAA CAS 64-19-7)
Lub cev muaj zog
- Lub xeev thiab qhov tshwm sim: Acetic Acid (CH₃COOH) muaj cov xim tsis muaj xim, pob tshab kua ntawm tus qauv kub thiab siab, emitting ib tug muaj zog pungent tsw (xws li, 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: Exhibits qaug 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.
