Ntiaj teb no thov rauAcetic Acid (CAS 64-19-7)txuas ntxiv hloov pauv raws li kev lag luam downstream-xws li vinyl acetate monomer (VAM), PTA, cov kuab tshuaj, thiab tshuaj- teb rau cov kev hloov pauv ntawm cov nqi roj av, cov nqi thauj khoom, thiab cov peev txheej tsim khoom hauv cheeb tsam.
Thaum lub Kaum Ib Hlis 2025, kev lag luam acetic acid qhia tau tias ruaj khov-rau- tus nqi ruaj khov thoob plaws ntau thaj tsam. Tuam Tshoj, raws li lub ntiaj teb cov neeg tsim khoom loj tshaj plaws, tau pom tus nqi nruab nrab rov qab los ntawm kev saib xyuas cov nroj tsuag thiab kev ua kom nruj. Lub caij no, South American importers tseem ntsib cov nqi thauj khoom siab thiab cov txiaj ntsig hloov pauv, thawb tus nqi nce.
Cov kws tshuaj ntsuam xyuas kev lag luam tau kwv yees tias Q4 2025 rau Q1 2026 yuav muaj kev nce siab ntxiv, txhawb nqa los ntawm kev xav tau zoo dua los ntawm cov txheej txheem, cov nplaum, thiab acetate kev lag luam.
Hauv qab no yog qhov tseeb hauv cheeb tsam tus nqi sib piv rau acetic acid kua:
| Thaj tsam | Tus nqi tam sim no (USD / MT) | Txoj Kev |

Hais txog Acetic Acid (CAS 64-19-7)
Acetic acid, tseem hu ua ethanoic acid, muaj cov qauv molecular C₂H₄O₂. Nws yog xim tsis muaj xim, pob tshab kua nrog ib tug pungent tsw. Nyob rau hauv cov txheej txheem, nws melting point yog 16.7 degree, boiling point yog 118 degree, txheeb ze ceev ntawm 20℃yog 1.049, viscosity ntawm 20℃yog 1.22 mPa·s, thiab refractive index ntawm 20℃yog 1.3715. Thaum anhydrous acetic acid solidifies ntawm qhov kub thiab txias, nws tsim cov dej khov -zoo li cov khoom hu ua acetic acid ice, thiab nws cov ntim nce thaum lub sij hawm solidification.

Cov txheej txheem acetic acid
Acetic acid tau npaj rau ntawm qhov chaw lag luam los ntawm huab cua oxidation ntawm acetaldehyde, los ntawm oxidation ntawm ethanol (ethyl cawv), thiab oxidation ntawm butane thiab butene.
Kev siv acetic acid
Kev Tsim Kho Kev Lag Luam: Hauv kev tsim khoom, cov tshuaj acetic acid tau siv dav hauv kev tsim tshuaj lom neeg, kev tsim tshuaj, thiab textile dyeing. Lawv ua cov khoom siv raw lossis cov kuab tshuaj hauv ntau yam tshuaj lom neeg; Hauv cov txheej txheem tshuaj, cov tshuaj acetic acid feem ntau yog ua haujlwm los kho cov qib pH ntawm cov tshuaj; Hauv kev lag luam dyeing, lawv tau siv rau kev kho xim thiab txhim kho dye solubility.
Nyem qhov no kom tau txais qhov tseeb thoob ntiaj tebAcetic Acid (CAS 64-19-7)tus nqi lag luam rau 2025.
