Teb ceev
Glacial acetic acid thiab vinegar ob leeg muaj acetic acid (CH₃COOH, CAS 64-19-7), tab sis lawv yog cov khoom sib txawv.
Lub ntsiab tseem ceeb ntawm vinegar yog acetic acid, tseem hu ua ethanoic acid. Vinegar yog diluted daws ntawm acetic acid. Tsev neeg dawb vinegar yog ib qho kev daws teeb meem ntawm acetic acid. Los ntawm 10% muaj concentrated vinegar mus rau ntau tshaj 99% glacial acetic acid, tag nrho cov concentrations siv tib molecule (CH₃COOH). Kev nkag siab txog qhov sib txawv ntawm glacial acetic acid thiab vinegar yog ib qho tseem ceeb rau cov neeg yuav tshuaj, cov khw muag khoom noj, cov chaw kuaj mob, thiab cov neeg siv khoom lag luam.
Glacial Acetic Acid yog dab tsi?
Glacial acetic acid (GAA) Cov tshuajyog ib daim ntawv muaj concentrated heev ntawm acetic acid, nrog ib tug concentration ntawm tsawg kawg yog 99%.
Nws yog cov kua tsis muaj xim uas siv dav hauv tshuaj, tshuaj, textile ua, muaj kuab tshuaj, thiab tshuaj synthesis industries.
Lo lus "glacial" yog hais txog nws cov cuab yeej ntawm kev tsim cov dej khov dej khov ntawm qhov kub hauv qab 16.6 degree.

- Raws li txoj cai: FDA 21 CFR 184.1005, EU E260 preservative
Dab tsi yog qhov txawv ntawm glacial acetic acid thiab vinegar?
Qhov tseem ceeb tshaj qhov txawv yog qhov concentration thiab npaj siv. Glacial acetic acid (CAS 64-}19-7) yog cov tshuaj muaj zog heev uas tsim los rau kev tsim cov txheej txheem, thaum vinegar yog cov khoom noj khoom haus diluted rau cov neeg siv khoom siv ncaj qha.

Qhov txawv ntawm kev nyab xeeb
Glacial acetic acid (GAA) yog ib qho tshuaj muaj zog heev uas tuaj yeem ua rau tawv nqaij kub hnyiab, qhov muag loj, thiab khaus khaus yog tias nqus tau los yog nqos. Nws yuav tsum tau ua nrog cov cuab yeej kev nyab xeeb thiab kev saib xyuas kom raug.
Vinegar yog ib qho khoom noj uas muaj kuab lom- qib khoom uas feem ntau muaj kev nyab xeeb rau kev ua noj thiab siv hauv tsev. Nws yuav ua rau mob me me hauv qee kis tab sis muaj kev nyab xeeb dua li glacial acetic acid.

Puas yog Glacial Acetic Acid Diluted Ua Vinegar?
Technically, acetic acid tuaj yeem diluted nrog dej huv kom ncav cuag cov ntsiab lus zoo ib yam li vinegar. Txawm li cas los xij, kev lag luam -qib glacial acetic acid tsis yog npaj rau kev siv zaub mov. Yog vim li cas tsis tas yuav purity theem, tab sis kev cai raws cai thiab impurity specifications.
Qhov tseem ceeb Distinctions
Khoom noj khoom haus- Qib Acetic Acid:
- Ua raws li cov kev cai ntawm kev nyab xeeb khoom noj
- Ua tau raws li FCC lossis sib npaug specifications
- Pom zoo rau daim ntawv thov ua zaub mov
Industrial-Qib Acetic Acid:
- Manufactured rau industrial siv
- Tsis muaj ntawv pov thawj rau kev sib cuag zaub mov
- Yuav tsum tsis txhob siv ncaj qha rau hauv kev tsim khoom noj
Cov khoom uas ua los ntawm cov khoom noj diluted -qib acetic acid feem ntau hu ua hluavtaws los yog cov kua txiv hmab txiv ntoo thiab tej zaum yuav xav tau cov ntawv tshwj xeeb nyob ntawm cov kev cai hauv zos.
Safety Note:
Thaum diluting concentrated acetic acid, nco ntsoov ntxiv cov kua qaub rau hauv dej; tsis txhob ntxiv dej rau cov kua qaub. Qhov no minimizes tshav kub tiam thiab txo qhov kev pheej hmoo ntawm splashing.
Cov lus nug nquag
Lub ntsiab acid nyob rau hauv vinegar yog acetic acid, nws lub npe systematic yog acetic acid (los yog acetic acid). Cov kua txiv hmab hauv tsev feem ntau yog cov tshuaj aqueous ntawm acetic acid.
Yog, vinegar yog acidic heev. Nws cov acidity nyob ntawm qhov concentration ntawm acetic acid, xws li cov tshuaj hauv tsev me me mus rau kev ua haujlwm hnyav heev (xws li 30% lossis 75% vinegar).
Ethanoic acid yog International Union of Pure and Applied Chemistry (IUPAC) systematic lub npe rau acetic acid. Nws yog tib yam tshuaj lom neeg sib xyaw (CH3COOH) uas muab cov kua txiv hmab txiv ntoo qaub saj thiab tsw ntxhiab tsw.
Yog lawm, glacial acetic acid GAA tuaj yeem diluted nrog dej kom txo qis concentration vinegar, xws li 10% lossis 30%. Ib txwm ntxiv cov kua qaub rau hauv dej thiab sab laj nrog Daim Ntawv Qhia Txog Kev Nyab Xeeb (SDS) rau cov txheej txheem kev nyab xeeb.
