Cov kua qaub acetic /əˈsiːtɪk/, lub npe hu ua systematicallyethanoic acid /ˌɛθəˈnoʊɪk/yog ib qho kua qaub, tsis muaj xim thiabcov organic sib xyawnrog raucov qauv tshuaj lom neegCH3COOH (tseem sau ua CH3CO2H, C2H4O2, lossis HC2H3O2).Kua txiv qaubmuaj tsawg kawg yog 4% acetic acid los ntawm qhov ntim, ua rau acetic acid yog cov khoom tseem ceeb ntawm cov kua txiv hmab tsis suav nrog dej. Nws tau siv, ua ib feem ntawm cov kua txiv hmab, thoob plaws keeb kwm txij li tsawg kawg yog xyoo pua thib peb BC.

Acetic acid yog qhov thib ob yooj yim tshaj plawscarboxylic acid(tom qabkua qaub formic). Nws yog ib qho tseem ceebtshuaj reagentthiab kev lag luam tshuaj lom neeg thoob plaws ntau qhov chaw, siv feem ntau hauv kev tsim khoomcellulose acetaterauzaj duab xis,polyvinyl acetaterau ntookua nplaum, thiab cov xov paj thiab cov ntaub ua los ntawm cov khoom siv hluavtaws. Hauv tsev neeg, cov kua qaub acetic diluted feem ntau siv rau hauvcov neeg sawv cev descaling. Nyob rau hauv lubkev lag luam zaub mov, acetic acid yog tswj los ntawmcov cai ntxiv rau khoom nojE260 ua ib qhocov tshuaj tswj aciditythiab ua ib qho khoom noj qab zib. Hauvkev tshawb fawb txog lub cev, tuspawg acetyl, muab los ntawm acetic acid, yog qhov tseem ceeb rau txhua yam ntawm lub neej. Thaum khi raucoenzyme A, nws yog qhov tseem ceeb raukev ua haujlwm ntawm lub cevntawmcov carbohydratesthiabcov rog.

Kev thov thoob ntiaj teb rau acetic acid txij li xyoo 2023 yog li ntawm 17.88 labmetric tonnesib xyoos (t/a). Feem ntau ntawm lub ntiaj teb cov acetic acid yog tsim los ntawmkev ua kom carbonylationntawmmethanolNws cov khoom tsim tawm thiab kev siv hauv kev lag luam tom qab ntawd ua rau muaj kev phom sij rau cov neeg ua haujlwm kev noj qab haus huv, suav nrog kev puas tsuaj rau daim tawv nqaij thiab kev raug mob ua pa ntev los ntawm kev ua pa.
