Kev siv glacial acetic acid

Kev siv cov glacial acetic acid,
Glacial acetic acid, glacial acetic acid nyhuv, Glacial Acetic Acid Chaw tsim tshuaj paus, glacial acetic acid qauv, siv glacial acetic acid, glacial acetic acid siv thiab cov nyhuv,
Cov lus qhia zoo (GB / T 1628-2008)

Physicochemical zog:
1. Colorless kua thiab irritating dour.
2. Melting point 16.6 ℃;boiling point 117.9 ℃;Kev kub ceev: 39 ℃.
3. Solubility dej, ethanol, benzene thiab ethyl ether immiscible, insoluble hauv carbon disulphide.

Cia:
1. Khaws rau hauv qhov chaw txias, cua txias.
2. Cia kom deb ntawm qhov hluav taws kub, cua sov.Lub caij txias yuav tsum tswj qhov kub siab tshaj 16 ° C, kom tsis txhob muaj kev sib zog.Thaum lub caij txias, qhov kub yuav tsum tau khaws cia siab tshaj 16 ° C kom tiv thaiv kom tsis txhob khov.
3. Khaws lub thawv kaw.Yuav tsum tau sib cais los ntawm oxidant thiab alkali.Kev sib tov yuav tsum zam los ntawm txhua txoj kev.
4. Siv lub teeb pom kev tawg, qhov chaw ua pa.
5. Cov cuab yeej siv tshuab thiab cov cuab yeej uas txwv tsis pub siv yooj yim los tsim cov nplaim taws.
6. Cov chaw khaws cia yuav tsum tau nruab nrog cov khoom siv kho mob xwm txheej ceev thiab cov khoom siv hauv tsev tsim nyog.

Siv:

1.Derivative: Mas siv nyob rau hauv synthetising acetic anhydride, acetic ether, PTA, VAC / PVA, CA, ethenone, chloroacetic acid, thiab lwm yam
2. Pharmaceutical: Acetic acid ua kuab tshuaj thiab tshuaj raw cov ntaub ntawv, feem ntau yog siv rau zus tau tej cov penicilin G potas-sium, penicilin G sodium, penicillin procaine, acetanilide, sulfamethoxazole, thiab sulfamethoxazole isoxazole, norfloxacin, ciprofloxacin, lic acetylphenone salicycin acid. caffeine, thiab lwm yam.
3.Intermediate: acetate, sodium hydrogen di, peracetic acid, thiab lwm yam
4.Dyestuff thiab textile printing thiab dyeing: Feem ntau yog siv los tsim disperse dyes thiab vat dyes, thiab textile printing anddyeing processing
5. Synthesis ammonia: Nyob rau hauv daim ntawv ntawm cuprammonia acetate, siv nyob rau hauv refining syngas kom tshem tawm ib tug litl CO thiab CO2.
6. Duab: Tus tsim tawm
7. Ntuj roj hmab: Coagulant
8. Kev tsim kho kev lag luam: Tiv thaiv pob zeb los ntawm frezing9.Hauv addtin kuj tau siv dav hauv kev kho dej, hluavtaws fiber, tshuaj tua kab, yas, tawv, xim, hlau ua thiab roj hmab kev lag luam

Glacial acetic acid (ntshiab teeb meem), uas yog, anhydrous acetic acid, acetic acid yog ib qho tseem ceeb organic acids, organic compounds.Nws solidifies rau hauv dej khov ntawm qhov kub thiab txias, feem ntau hu ua glacial acetic acid.Volume expansion thaum lub sij hawm solidification yuav ua rau lub thawv tawg.Flash point 39 ℃, tawg txwv 4.0% ~ 16.0%, qhov siab tshaj plaws tso cai rau huab cua tsis ntau tshaj 25mg / m3.Ntshiab acetic acid yuav khov rau hauv cov dej khov dej khov hauv qab lub melting point, yog li anhydrous acetic acid kuj hu ua glacial acetic acid.

siv
Daim ntawv thov: Feem ntau yog siv rau kev sib txuas ntawm vinyl acetate, acetate fiber, acetic anhydride, acetate, hlau acetate thiab halogenated acetic acid.Nws kuj yog ib qho tseem ceeb raw khoom rau kws tshuaj, zas xim, tshuaj tua kab thiab lwm yam organic synthesis.Tsis tas li ntawd, nws kuj tau siv dav hauv kev tsim cov tshuaj yees duab, cellulose acetate, textile printing thiab dyeing thiab roj hmab industries, cov kuab tshuaj rau kev tsim cov yas, dyes, photography, tshuaj, tshuaj tua kab thiab lwm yam raw khoom rau organic synthesis.
