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
Glacial acetic acid feem ntau hu ua acetic acid. Glacial acetic acid tov tuaj yeem siv kho mob los kho ntau yam kab mob ntawm daim tawv nqaij, txawm tias cov kab mob fungal. Thaum glacial acetic acid siv los kho cov kab mob fungal, 30% kev daws ntawm glacial acetic acid feem ntau yog siv. Nws yog siv los kho cov ntsia hlau grey, uas tuaj yeem siv tom qab ntxuav cov ntsia hlau mob thiab ua rau cov ntsia hlau thinning. Cov tawv nqaij nyob ib sab ntawm tus ntsia thawv tuaj yeem tiv thaiv nrog ib txheej ntawm roj av jelly. Thaum kho pob kws thiab warts ntawm daim tawv nqaij, koj yuav tsum ntxuav cov kab mob ua ntej siv cov tshuaj, soak hauv dej kub, thiab tom qab ntawd siv cov tshuaj. Nws yuav tsum raug sau tseg tias vim tias glacial acetic acid muaj cov nyhuv corrosive, nws yog qhov zoo tshaj kom tsis txhob siv cov kab mob fungal ntawm lub ntsej muag. Thaum siv, nco ntsoov xyuam xim rau, ntxiv rau qhov mob, lwm qhov ntawm daim tawv nqaij yog qhov zoo tshaj plaws los siv Vaseline los tiv thaiv.
