Kev qhia tshwj xeeb (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 los tiv thaiv / 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 cuab yeej kho mob xwm txheej ceev thiab cov khoom siv vaj tse 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, licacetylephenone salicylic 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

Acetic acid, tseem hu ua acetic acid (36% -38%), glacial acetic acid (98%), tshuaj formula CH3COOH, yog ib qho organic monic acid, cov ntsiab lus ntawm vinegar. Ntshiab anhydrous acetic acid (glacial acetic acid) yog cov xim tsis muaj xim hygroscopic nrog qhov chaw khov ntawm 16.6 ° C (62 ° F) thiab dhau los ua cov xim tsis muaj xim tom qab solidification. Nws cov tshuaj aqueous yog tsis muaj zog acidic thiab erosive, thiab chav ua kom khaus rau lub qhov muag thiab qhov ntswg.

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

Nws tuaj yeem pom tias ob qhov tsis zoo ib yam, lub teeb nyem ntawm cov dej khov acetic acid yog 39 ℃, qhov txwv tawg yog 4.0% ~ 16.0%, thiab qhov siab tshaj plaws tso cai rau huab cua tsis tshaj 25mg / m3, uas yog rau cov khoom txaus ntshai, thiab acetic acid tsis yog cov khoom txaus ntshai.
