Acetic Acid yog ib hom tshuaj lom neeg reagent siv nyob rau hauv ntau ntawm cov organic tshua. Nws yog cov dej cawv tseem ceeb ntawm cov dej qab zib, ua rau nws txawv saj thiab tsw. Nws yog siv nyob rau hauv kev sib txuas ntawm zas-hnov mob hlwb hnub ci. Acetic acid yog cov kua tsis muaj xim lossis siv lead ua nrog kua qaub, vinegar zoo li tsis hnov ​​tsw thiab yog ib qho ntawm cov carboxylic acids uas yooj yim tshaj plaws thiab yog cov tshuaj siv dav siv tshuaj lom neeg. Acetic acid muaj cov ntawv thov dav dav raws li lub chaw kuaj tshuaj, hauv kev tsim cov cellulose acetate feem ntau rau cov yeeb yaj kiab duab thiab polyvinyl acetate rau cov kua nplaum, cov tshuaj hluavtaws, thiab cov ntaub. Acetic acid kuj tau siv dav siv raws li cov tshuaj tiv thaiv kab mob thiab acidity regulator hauv kev lag luam khoom noj khoom haus. Acetic acid tshwm sim hauv cov kua qaub. Nws ua nyob rau hauv cov ntoo distillation. Nws pom cov ntawv thov dav dav hauv kev lag luam chemical. Nws yog siv rau hauv kev tsim cov cellulose acetate, acetate rayon, thiab ntau yam acetate thiab acetyl tebchaw; raws li cov kuab tshuaj rau cov pos hniav, roj, thiab tawv; raws li cov khoom noj khoom haus khaws cia hauv luam ntawv thiab dyeing; thiab hauv organic synthesis. Glacial acetic acid yog qhov tseem ceeb rau kev lag luam chemical. Cov tshuaj tiv thaiv ntawm acetic acid nrog hydroxyl muaj cov sib txuas, tshwj xeeb tshaj yog cov cawv, ua rau muaj kev tsim cov acetate esters. Kev siv ntau tshaj ntawm cov kua qaub acetic yog nyob rau hauv cov vinyl acetate. Vinyl acetate tuaj yeem tsim tawm los ntawm cov tshuaj tiv thaiv ntawm acetylene thiab acetic acid. Nws kuj yog tsim los ntawm ethylene thiab acetic acid. Vinyl acetate yog polymerized rau hauv polyvinyl acetate (PVA), uas yog siv rau hauv kev tsim cov tshuaj, cov yeeb yaj kiab, cov nplaum thiab cov xim pleev xim.
