Kev lag luam hauv tsev acetic acid yog ua haujlwm ntawm kev tos-thiab-saib, thiab tam sim no tsis muaj kev ntxhov siab rau cov khoom lag luam.Lub hom phiaj tseem ceeb yog ntawm kev xa khoom nquag, thaum qhov kev thov qis qis yog qhov nruab nrab.Kev lag luam kev lag luam huab cua tseem zoo, thiab kev lag luam muaj kev tos-thiab-pom kev xav.Kev xa khoom thiab kev thov yog qhov sib npaug, thiab tus nqi sib txawv ntawm acetic acid tsis muaj zog thiab ruaj khov.
Raws li lub Tsib Hlis 30, tus nqi nruab nrab ntawm acetic acid nyob rau sab hnub tuaj Suav teb yog 3250.00 yuan / ton, txo qis ntawm 1.02% piv rau tus nqi ntawm 3283.33 yuan / ton rau lub Tsib Hlis 22nd, thiab nce ntawm 0.52% piv rau thaum pib ntawm lub Tsib Hlis 30. hli.Raws li lub Tsib Hlis 30, kev lag luam tus nqi ntawm acetic acid nyob rau hauv ntau thaj tsam hauv lub lim tiam yog raws li hauv qab no:

Cov khoom siv raw khoom methanol ua lag luam yog ua haujlwm nyob rau hauv qhov tsis muaj zog.Raws li lub Tsib Hlis 30, tus nqi nruab nrab hauv kev lag luam hauv tsev yog 2175.00 yuan / tuj, txo qis ntawm 0.72% piv rau tus nqi ntawm 2190.83 yuan / ton rau lub Tsib Hlis 22nd.Cov nqi yav tom ntej poob qis, kev lag luam thee nyoos txuas ntxiv kev nyuaj siab, kev lag luam kev ntseeg siab tsis txaus, kev xav tau qis qis rau lub sijhawm ntev, kev lag luam hauv kev lag luam methanol txuas ntxiv mus ntxiv, ua ke nrog cov khoom lag luam tsis tu ncua, methanol chaw lag luam tus nqi. ntau fluctuated.
Kev lag luam downstream acetic anhydride tsis muaj zog thiab poob qis.Raws li lub Tsib Hlis 30, lub Hoobkas nqi ntawm acetic anhydride yog 5387.50 yuan / ton, ib tug txo ntawm 1.69% piv rau tus nqi ntawm 5480.00 yuan / ton rau lub Tsib Hlis 22. Tus nqi ntawm acetic acid yog tus nqi qis, thiab tus nqi txhawb rau acetic. anhydride tsis muaj zog.Kev yuav khoom hauv qab ntawm acetic anhydride ua raws li qhov xav tau, thiab kev lag luam kev sib tham ua haujlwm, ua rau txo tus nqi ntawm acetic anhydride.
Hauv kev kwv yees kev lag luam yav tom ntej, acetic acid cov kws tshuaj ntsuam xyuas los ntawm Lub Koom Haum Lag Luam ntseeg tias cov khoom siv ntawm acetic acid nyob rau hauv kev ua lag luam tseem muaj txiaj ntsig, nrog cov tuam txhab lag luam nquag xa khoom thiab kev siv qis qis qis.Kev yuav khoom hauv kev ua lag luam ua raws li qhov xav tau, thiab kev lag luam kev lag luam tau txais txiaj ntsig.Cov neeg ua haujlwm muaj kev tos-thiab-pom lub siab xav, thiab xav tias kev lag luam acetic acid yuav ua haujlwm nyob rau hauv ib qho chaw yav tom ntej.Kev saib xyuas tshwj xeeb yuav raug them rau kev ua raws li nram qab no.
