Qib kev lag luam 99.8% glacial acetic acid (CAS 64‑19‑7, UN 2789, cov mis tshuaj CH₃COOH) yog ib qho ntawm cov tshuaj lom neeg tseem ceeb tshaj plaws hauv kev tsim khoom thoob ntiaj teb niaj hnub no. Cov khoom no yog cov kua tsis muaj xim nrog cov ntxhiab tsw qab ntxiag, muag dav thoob plaws cov khoom siv tshuaj lom neeg thoob ntiaj teb hauv 30 kg nruas, 215 kg nruas thiab IBC tanks rau kev thauj khoom ntau yam.

Cov ntaub ntawv kev lag luam tsis ntev los no qhia txog kev hloov pauv tseem ceeb rau cov kua qaub glacial acetic acid uas yog los ntawm Tuam Tshoj hauv xyoo 2026. Txij lub Ib Hlis mus txog rau lub Xya Hli, Tuam Tshoj cov khoom xa tawm ntawm cov kua qaub glacial acetic acid tau nce 32.95% txhua xyoo, thaum cov khoom xa tuaj ntawm cov khoom xa tuaj tau poob qis heev, ua pov thawj tias Tuam Tshoj muaj txiaj ntsig zoo hauv kev muab cov kua qaub glacial acetic acid thoob ntiaj teb. Cov sijhawm kho cov nroj tsuag txawv teb chaws nruj, cov nqi zog hauv cheeb tsam siab thiab kev siv cov peev xwm hauv tsev ruaj khov ua ke thawb kom muaj 99.8% glacial acetic acid uas muaj cov khoom huv si ntau dua mus rau sab hnub tuaj Asia, Middle East thiab lwm lub chaw tsim khoom txawv teb chaws.

Ua ib yam tshuaj lom neeg tseem ceeb, 99.8% glacial acetic acid txhawb nqa ntau txoj kev lag luam hauv qab. Nws ua haujlwm ua cov khoom noj tseem ceeb rau kev tsim cov vinyl acetate monomer, acetic anhydride, ntau yam acetate esters thiab cellulose acetate cov khoom, uas pub ntxiv rau kev lag luam txheej, nplaum thiab ntim khoom. Hauv cov khoom lag luam zoo, nws koom nrog kev tsim cov diethyl malonate, ethyl acetoacetate thiab ntau yam ntsev acetate. Nws kuj ua lub luag haujlwm tseem ceeb rau kev tsim cov khoom siv tshuaj suav nrog aspirin, nrog rau cov khoom siv raw rau tshuaj tua kab, dyestuff thiab cov tshuaj siv duab. Dhau li ntawd, cov chaw luam ntawv textile-dyeing siv glacial acetic acid los kho tus nqi pH rau kev zas xim ntaub, thiab cov chaw tsim roj hmab siv nws ua tus neeg sawv cev tseem ceeb hauv kev tsim roj hmab.

Rau cov neeg yuav khoom lag luam thoob ntiaj teb, kev ua raws li cov khoom lag luam yog qhov tseem ceeb heev. Cim tias yog UN 2789 cov khoom txaus ntshai, glacial acetic acid xav tau kev ntim khoom raws li tus qauv thiab kev tswj hwm kev thauj mus los nruj. Cov neeg muag khoom txhim khu kev qha muab cov khoom ruaj khov 99.8% glacial acetic acid nrog cov ntaub ntawv tiav uas suav nrog HS code 29152119, cov ntaub ntawv kev nyab xeeb thiab cov ntaub ntawv qhia txog kev thauj khoom (22.2 tons rau 30 kg nruas, 17.2 tons rau 215 kg nruas, 21 tons rau IBC tanks). Tawm tsam keeb kwm yav dhau los ntawm cov nqi khoom siv tshuaj lom neeg thoob ntiaj teb hloov pauv, cov kua qaub glacial acetic acid qib kev lag luam uas tsim nyog nrog kev ntshiab tas li tseem yog lub hom phiaj tseem ceeb rau kev tsim tshuaj lom neeg, kev ua tshuaj thiab cov lag luam textile thoob ntiaj teb.
