CAS 64-19-7 Glacial acetic acid (GAA), siab -purity daim ntawv ntawm anhydrous acetic acid, feem ntau tshaj li 99% purity, yog dav siv los ua raw khoom tseem ceeb, hnyav, thiab tshuaj nruab nrab nyob rau hauv ntau yam kev lag luam sectors. Vim nws muaj zog acidity, siab reactivity, thiab zoo heev solubility, glacial acetic acid plays lub luag hauj lwm tseem ceeb nyob rau hauv tshuaj synthesis, manufacturing txheej txheem, thiab loj -scale industrial ntau lawm.
Glacial acetic acid CAS 64-19-7 yog dab tsi?
Glacial acetic acid yog qhov tseem ceeb ntshiab anhydrous acetic acid. Undiluted, nws yog cov kua tsis muaj xim uas tuaj yeem ua rau dej khov- zoo li cov muaju ntawm qhov kub thiab txias hauv qab 16.6 degree.
Tsis zoo li diluted acetic acid, GAA feem ntau muaj purity ntau dua 99%. Qhov no purity siab muab nws tsis tshua muaj siab reactivity, ua rau nws haum rau industrial daim ntaub ntawv, tab sis nws corrosiveness yuav tsum tau ceev faj tuav.
Glacial Acetic Acid ua li cas?
Muaj ob txoj kev tseem ceeb:
Thawj, thiab tam sim no txoj kev siv dav tshaj plaws, yog txoj kev methanol carbonylation. Txoj kev no suav nrog cov tshuaj tiv thaiv methanol nrog cov pa roj carbon monoxide nyob rau hauv cov xwm txheej catalytic los tsim acetic acid.
Txoj kev thib ob yog bio-fermentation. Nws txoj cai zoo ib yam li vinegar brewing, tab sis cov txheej txheem yog optimized. Qhov no yields acetic acid nrog ntau purity, tab sis ntxiv refining tseem yuav tsum tau.
Txawm hais tias siv txoj hauv kev ntau lawm, cov txiaj ntsig ntawm acetic acid yuav tsum tau ua kom huv ntxiv, xws li tshem tawm cov dej noo, ua ntej nws tuaj yeem siv los tsim glacial acetic acid.

glacial acetic acid siv hauv kev lag luam
Glacial acetic acid muaj ntau yam kev siv hauv ntau qhov kev lag luam. Nws cov ntawv thov tseem ceeb suav nrog:
1. Kev Lag Luam Tshuaj thiab Yas Kev Lag Luam
High Purity Glacial Acetic Acid yog ib qho tseem ceeb raw khoom rau ntau cov tshuaj intermediates thiab polymer tebchaw. Nws yog siv los tsim cov yas acetate monomer (VAM), cov khoom siv tseem ceeb rau polyvinyl acetate (PVA), uas yog cov khoom siv raw rau cov xim, cov nplaum, thiab ntau yam txheej.
Hauv plastics thiab resin manufacturing, glacial acetic acid yog siv los tsim cellulose acetate rau zaj duab xis thiab textile fibers. Nws kuj tseem siv los tsim cov purified terephthalic acid (PTA), cov khoom siv tseem ceeb rau kev tsim PET yas ntim rau haus thiab ntim khoom noj.
2. Kev lag luam kws tshuaj thiab kev noj qab haus huv
99.5% Glacial acetic acid muaj purity siab thiab zoo tshuaj reactivity, ua rau nws haum raws li ib tug tshuaj reagent thiab polar proton hnyav nyob rau hauv cov tshuaj synthesis txheej txheem. Hauv API ntau lawm, GAA yog ib qho tseem ceeb hnyav thiab catalyst siv los tsim ntau yam tshuaj siv, xws li tshuaj aspirin, vitamins, tshuaj hormones, thiab tshuaj tua kab mob.
