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

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
Nyob rau hauv xyoo tas los no, kev lag luam tshuaj lom neeg kev lag luam hauv tsev thiab txawv teb chaws tau pom tseeb rau txhua tus.Txawm hais tias nyob rau hauv kev cuam tshuam ntawm ntau yam hauv ib puag ncig, ntau lub tuam txhab tshuaj lom neeg tseem tau ua tiav kev loj hlob tawm tsam tus qauv.Hauv kev lag luam tshuaj, Pengfa Chemical tau nthuav dav kev lag luam ib qib zuj zus raws li lub tuam txhab muaj kev ntseeg siab thiab cov kauj ruam ruaj khov, thiab tam sim no nws tau nce ntau hauv kev xa tawm txawv teb chaws.
Rau cov khoom, cov khoom lag luam zoo yog ib txwm nrhiav tom qab los ntawm feem coob ntawm cov neeg siv khoom.Raws li keeb kwm kev coj noj coj ua muaj zog, Pengfa Tshuaj tau txais kev qhuas los ntawm ntau tus neeg siv khoom rau nws cov khoom lag luam zoo.Rau kev lag luam tshuaj, cov khoom lag luam zoo, Kev pabcuam zoo tom qab muag yog qhov tseem ceeb rau peb los tsim kev lag luam.
Raws li kev lag luam tshuaj lom neeg kev lag luam maj mam tawm ntawm lub teb chaws thiab xa tawm mus rau txawv teb chaws, peb lub tuam txhab kev xa khoom tas mus li ntawm formic acid, glacial acetic acid, acetic acid tov, khoom sodium acetate thiab calcium formate tseem nyiam los ntawm ntau cov neeg siv khoom.Pengfa Tshuaj kuj tseem maj mam ua kom zoo dua ntawm nws cov txiaj ntsig tseem ceeb los txeeb lub khw.qhia thiab yeej qhov nyiam ntawm ntau tus neeg siv khoom.
