Vim li cas Glacial Acetic Acid hu ua "Glacial"?

Ntshiab acetic acid feem ntau hu ua glacial acetic acid. Lub npe no muab los ntawm nws lub cev tshwj xeeb: nws khov rau hauv dej khov -zoo li cov muaju ntawm qhov kub thiab txias me ntsis hauv qab chav tsev.

Acetic acid (CH3COOH) yog lub npe nrov rau ethanoic acid. Raws li ib tug organic compound, nws muaj ib tug pungent tsw thiab qaub saj - yam ntxwv zoo ib yam li vinegar, lub ntsiab feem ntawm uas yog diluted acetic acid.

Acetic acid uas muaj dej tsawg heev (tsawg dua 1%) yog hu ua anhydrous acetic acid, los yog glacial acetic acid. Nws solidifies rau hauv crystals ntawm kwv yees li 16.6 degree, zoo li cov dej khov nab kuab lossis cov dej khov dej khov, yog li lub npe "glacial acetic acid." Tshem tawm cov dej impurities los ntawm acetic acid stabilizes nws melting point ntawm no kub tsis tshua muaj.

Glacial acetic acid tuaj yeem ua kom huv los ntawm maj mam ntws diluted acetic acid los ntawm solidified acetic acid crystals. Ib yam li cov dej khov ntim cov dej ntshiab huv hauv dej hiav txwv, cov ntshiab acetic acid adheres rau cov khoom siv lead ua txheej, thaum impurities tseem nyob hauv cov kua dej thiab sib cais.

Cov ntaub ntawv ntxiv

Acetic acid yog ib qho tsis muaj zog acid vim yog ionization ntawm hydrogen atom hauv nws pawg carboxyl, tso tawm hydrogen proton. Nws raug cais raws li monoprotic tsis muaj zog acid nrog pKa tus nqi ntawm 4.76 hauv cov tshuaj aqueous.

Dab tsi yog Glacial Acetic Acid siv rau hauv kev lag luam?

Tshuaj Synthesis

Raws li lub hauv paus tsev thaiv, glacial acetic acid (CAS 64-19-7) yog ib qho tseem ceeb ua ntej ntawm kev tsim cov yas acetate monomer (VAM), siv rau hauv cov xim, cov nplaum, thiab cov coatings. Nws tuaj yeem hloov mus rau hauv acetic anhydride thiab ntau yam acetate esters.

Plastics thiab Polymers

GAA yog ib qho tseem ceeb raw khoom rau kev tsim cov polyethylene terephthalate (PET), ib tug polymer lug siv nyob rau hauv zus tau tej cov yas hwj thiab ntim khoom noj.

Textiles thiab Dyeing

Kev lag luam textile siv nws rau kev kho xim, hloov pH, thiab ua kom cov xim ci ntsa iab thiab ruaj khov thaum lub sij hawm ua tiav.

Pharmaceuticals

Acetic acid (Glacial) ua raws li ob qho tib si cov tshuaj tiv thaiv hnyav thiab cov catalyst, ua lub luag haujlwm tseem ceeb hauv kev sib txuas ntawm cov khoom xyaw tshuaj nquag (APIs), suav nrog cov tshuaj xws li cov vitamins, tshuaj hormones, thiab tshuaj aspirin.

Khoom noj khoom haus thiab dej haus

Thaum diluted, nws yog siv nyob rau hauv kev lag luam khoom noj khoom haus raws li cov khoom noj additive E260. Nws yog siv nyob rau hauv cov khoom xws li pickles, kua txiv, thiab marinades raws li ib tug acidity regulator, flavoring agent, thiab antibacterial preservative.

Ntxuav thiab tua kab mob

Vim tias nws tsis yog - tshuaj lom thaum siv ntawm qhov muaj kev nyab xeeb, nws tuaj yeem siv los ua tus neeg ua haujlwm descaling zoo heev, tshuaj tua kab mob, thiab tshuaj tua kab mob, tsim nyog rau kev ua zaub mov thiab khoom siv kho mob.

Electronics thiab Agriculture

CAS 64-19-7 Glacial acetic acid yog siv rau hauv kev lag luam hluav taws xob, xws li etching thiab tu vaj huam sib luag pawg thawj coj saib; Nws kuj yog siv rau hauv kev ua liaj ua teb, xws li kev tsim cov tshuaj tua kab tshwj xeeb thiab tshuaj tua kab.
