Tuam Tshoj Tus Nqi Zoo Glacial Acetic Acid CAS: 64-19-7

1.Acetic acid tshwm sim hauv vinegar.Nws yog tsim nyob rau hauv lub destructive distillation ntawm ntoo.Nws pom ntau daim ntawv thov hauv chemicalindustry.Nws yog siv rau hauv kev tsim cov cellulose acetate, acetate rayon, thiab ntau yam acetate thiab acetyl compounds;raws li cov kuab tshuaj rau cov pos hniav, roj, thiab resins;ua zaub mov preservative hauv printing thiab dyeing;thiab nyob rau hauv organicsynthesis.
2.Acetic acid yog ib qho tseem ceeb ntawm kev lag luam tshuaj.Cov tshuaj tiv thaiv ntawm acetic acid nrog hydroxyl uas muaj cov ntsiab lus, tshwj xeeb tshaj yog cawv, ua rau tsim cov acetate esters.Kev siv ntau tshaj plaws ntawm acetic acid yog nyob rau hauv kev tsim cov yas acetate.Vinyl acetate tuaj yeem tsim los ntawm cov tshuaj tiv thaiv ntawm acetylene thiab acetic acid.Nws kuj yog tsim los ntawm ethylene thiab acetic acid.Vinyl acetate yog polymerized rau hauv polyvinyl acetate (PVA), uas yog siv nyob rau hauv zus tau tej cov fibers, films, adhesives, thiab latex xim.
Cellulose acetate, uas yog siv nyob rau hauv textiles thiab yees duab zaj duab xis, yog tsim los ntawm reacting cellulose nrog acetic acid thiab acetic anhydride nyob rau hauv lub xub ntiag ntawm sulfuric acid.Lwm cov esters ntawm acetic acid, xws li ethyl acetate thiab propyl acetate, yog siv ntau yam kev siv.
Acetic acid yog siv los tsim cov yas polyethylene terephthalate (PET).Acetic acid yog siv los tsim tshuaj.
3.Glacial Acetic Acid yog ib qho acidulant uas yog cov kua ntshiab, tsis muaj xim uas muaj kua qaub saj thaum diluted nrog dej.Nws yog 99.5% lossis siab dua hauv purity thiab crystallizes ntawm 17 ° c.Nws yog siv nyob rau hauv nyias hnav khaub ncaws nyob rau hauv ib daim ntawv diluted los muab cov acetic acid uas yuav tsum tau.Nws yog siv raws li ib tug preservative, acidulant, thiab flavoring neeg sawv cev.Nws tseem hu ua acetic acid, glacial.
4.Acetic acid yog siv los ua lub rooj vinegar, raws li preservative thiab raws li ib tug intermediate nyob rau hauv cov tshuaj kev lag luam, xws li acetate fibers, acetates, acetonitrile, tshuaj, fragrances, softening agents, dyes (indigo) thiab lwm yam khoom ntaub ntawv Sheet.
5.Nws yog siv rau hauv aqueous thiab non-aqueous acid-base titrations.
6.Kev tsim khoom ntawm ntau yam acetates, acetyl compounds, cellulose acetate, acetate rayon, plastics thiab roj hmab hauv tanning;raws li khaub ncaws qaub;luam ntawv calico thiab dyeing silk;raws li acidulant thiab preservative nyob rau hauv cov khoom noj;hnyav rau cov pos hniav, resins, roj volatile thiab ntau lwm yam khoom.Siv dav hauv kev lag luam organic syntheses.Pharmaceutic pab (acidifier).
