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 yog ib qho yooj yim carboxylic acid thiab ib qho tseem ceeb tshuaj reagent. Elebrium kuj tseem siv los ua polyethoethyls hauv acetate thiab polyetate nyob rau hauv cov nplaum hauv cov yeeb yaj kiab zaj duab xis, nrog rau ntau cov khoom siv hluavtaws thiab cov ntaub. Nws yog tsuas yog siv los ua ke cov khoom xws li ethyl acetate, acetate, acetate, thiab chlorine -album acid. Nws yog ib qho tseem ceeb raw khoom rau hluavtaws fiber ntau, nplaum, tshuaj, tshuaj tua kab thiab dyes. Nws kuj yog ib qho hnyav hnyav heev. Nws kuj yog nrov heev hauv kev lag luam.

Acetic acid tuaj yeem siv los ua cov kua qaub regulators, acidification agents, pickles, tsw nce tus neeg sawv cev, txuj lom, thiab lwm yam. Nws kuj yog ib tug zoo anti-microbiological tus neeg saib xyuas, uas yog mas vim nws yuav txo tau cov pH ntawm pH rau ** kab mob.

Acetic acid yog ib daim ntawv thov ua ntej thiab siv nyob rau hauv kuv lub teb chaws, uas yog tsuas yog siv rau composite seasoning, mis nyuj, kaus poom, cheese, jelly, thiab lwm yam. Thaum siv rau seasonings, koj muaj peev xwm dilute dej mus rau 4% mus rau 5% kev daws, thiab ntxiv. nws mus rau ntau yam seasonings. Cov dej qab zib ua los ntawm cov kua txiv hmab txiv ntoo ua cov qaub saj, ntxiv los ntawm cov khoom noj qab haus huv * khoom noj qab haus huv hu ua * hom * peb tiam ntawm cov dej haus.

Nthuav cov ntaub ntawv:

Kev npaj ntawm acetic acid: Nws tuaj yeem ua ke nrog phau ntawv synthesis thiab cov kab mob fermentation. Txoj kev sib xyaw ua ke lom neeg, uas yog, kev siv cov kab mob fermentation, tsuas yog 10% ntawm tag nrho lub ntiaj teb cov khoom tsim tawm, tab sis nws tseem yog ib txoj hauv kev tseem ceeb rau kev tsim cov acetic acid, tshwj xeeb tshaj yog vinegar, vim hais tias cov zaub mov kev nyab xeeb nyob rau hauv ntau qhov chaw stipulate. uas vinegar nyob rau hauv cov zaub mov yog los ntawm biology. Txoj kev cai lij choj, thiab txoj kev fermentation tau muab faib ua aerobic fermentation method thiab anaerobic fermentation method.

Nyob rau hauv cov ntaub ntawv ntawm cov pa ntau, cov kab mob ntawm vinegar tuaj yeem tsim acetic acid los ntawm cov khoom noj uas muaj cawv. Feem ntau siv cov kua txiv hmab txiv ntoo lossis cawv txiv hmab sib xyaw nplej, malt, mov lossis qos yaj ywm rau ferment. Cov tshuaj sib npaug uas yog fermented los ntawm cov kab mob no yog:

C? HOH + O? → CH? COV + H? O

Qee cov tswv cuab ntawm cov kab mob anaerobic, suav nrog qee cov tswv cuab ntawm genus Ritula, tuaj yeem hloov cov suab thaj ncaj qha rau hauv ethanol yam tsis tas yuav tsum muaj ethanol li nruab nrab.
