1. Kev soj ntsuam ntawm acetic acid kev lag luam sib txawv
Thaum Lub Ob Hlis, acetic acid tau pom qhov hloov pauv, nrog tus nqi nce ua ntej thiab tom qab ntawd poob. Thaum pib ntawm lub hli, tus nqi nruab nrab ntawm acetic acid yog 3245 yuan / tuj, thiab thaum kawg ntawm lub hli, tus nqi yog 3183 yuan / ton, nrog rau qhov txo qis ntawm 1.90% hauv lub hli.
Thaum pib ntawm lub hli, kev lag luam acetic acid tau ntsib nrog cov nqi siab thiab kev xav tau zoo dua. Tsis tas li ntawd, vim yog kev tshuaj xyuas ib ntus ntawm qee cov khoom siv, cov khoom siv tau poob qis, thiab tus nqi nyob rau sab qaum teb tau nce ntau heev; Txij thaum nruab nrab ntawm lub hli mus txog rau lub hli tas los, kev ua lag luam tsis muaj txiaj ntsig ntxiv, tus nqi siab yog qhov nyuaj rau kev txhawb nqa, thiab kev lag luam tig mus poob. Cov nroj tsuag maj mam rov ua haujlwm, tag nrho cov khoom txaus txaus, thiab qhov tsis sib xws ntawm cov khoom siv thiab kev xav tau ua rau poob ntawm tus nqi kom zoo dua. Thaum kawg ntawm lub hli, tus nqi pauv tseem ceeb ntawm acetic acid nyob rau hauv thaj tsam ntawm 3100-3200 yuan / ton.
2. Kev soj ntsuam kev lag luam sib txawv ntawm ethyl acetate
Lub hlis no, domestic ethyl acetate nyob rau hauv ib tug tsis muaj zog poob siab, thiab lub ntsiab factories nyob rau hauv Shandong pib ua hauj lwm, thiab cov khoom tau nce piv nrog rau qhov ntawd. Cov ethyl acetate tau raug txwv los ntawm cov khoom siv xoob thiab kev thov, tshwj xeeb tshaj yog nyob rau thawj kaum hnub, uas tsis paub txog cov txiaj ntsig ntawm cov nqi ntws ntawm acetic acid. Raws li kev txheeb cais ntawm Lub Chaw Haujlwm Xov Xwm Lag Luam, qhov poob ntawm lub hlis no yog 0.24%. Nyob ze rau lub hli kawg, tus nqi lag luam ntawm ethyl acetate yog 6750-6900 yuan / ton.
Yuav kom paub meej, kev lag luam huab cua ntawm ethyl acetate kev ua lag luam lub hlis no zoo li txias, thiab kev yuav khoom qis qis dua, thiab kev lag luam ntawm ethyl acetate nyob rau hauv thaj tsam ntawm 50 yuan. Nyob rau nruab nrab ntawm lub hli, txawm hais tias cov chaw tsim khoom loj tau hloov kho, qhov kev hloov pauv tau txwv, thiab feem ntau ntawm lawv tau tswj tsis pub dhau 100 yuan. Cov lus hais ntawm cov tuam txhab loj feem ntau tau ruaj khov, thiab cov nqi ntawm qee cov tuam txhab hauv Jiangsu tau txo qis me ntsis nyob rau nruab nrab lub hlis vim muaj kev cuam tshuam ntawm cov khoom muag siab. Shandong cov chaw tsim khoom loj tau sib tw rau cov khoom xa tuaj. Qhov kev sib tw tseem qhia tau tias tsis txaus ntseeg. Txawm hais tias muaj tus nqi them nqi, tus nqi tsis tau tshaj theem ntawm lub hli dhau los. Tus nqi ntawm cov khoom siv raw thiab acetic acid poob rau hauv nruab nrab thiab lig theem ntawm kev ua lag luam, thiab kev ua lag luam yuav ntsib tus nqi tsis zoo.
3. Kev lag luam sib piv ntawm butyl acetate
Lub hlis no, domestic butyl acetate rebounded vim yog cov khoom siv nruj. Raws li kev soj ntsuam ntawm Lub Chaw Haujlwm Xov Xwm Lag Luam, butyl acetate tau nce 1.36% nyob rau ib hlis. Thaum kawg ntawm lub hlis, tus nqi ntawm domestic butyl ester yog 7400-7600 yuan / ton.
Tshwj xeeb, kev ua tau zoo ntawm raw acetic acid tsis muaj zog, thiab n-butanol poob qis, nrog kev poob qis ntawm 12% hauv Lub Ob Hlis, uas yog qhov tsis zoo rau kev lag luam butyl ester. Lub ntsiab yog vim li cas vim li cas tus nqi ntawm butyl ester tsis ua raws li qhov poob yog tias ntawm cov khoom siv sab nrauv, kev khiav hauj lwm ntawm cov lag luam tseem qis, los ntawm 40% nyob rau lub Ib Hlis mus rau 35%. Kev muab khoom tseem nruj. Downstream tos-thiab-saib kev xav yog qhov hnyav, kev ua lag luam tsis muaj kev nqis tes ua, thiab kev lag luam ntawm kev txiav txim ntau yog tsawg, thiab qhov sib txawv hauv kaum hnub dhau los yog nyob rau hauv qhov tsis txaus ntseeg. Qee lub tuam txhab raug yuam kom kho raws li tus nqi siab, thiab cov khoom lag luam thiab kev thov tsis tau tawg.
4. Kev cia siab yav tom ntej ntawm acetic acid kev lag luam saw

Hauv lub sijhawm luv luv, kev ua lag luam sib xyaw nrog ntev thiab luv luv, thaum tus nqi tsis zoo, qhov kev thov tuaj yeem txhim kho. Ntawm qhov tod tes, tseem muaj kev poob qis ntawm cov nqi ntws, uas yuav coj cov xov xwm tsis zoo rau kev lag luam acetic acid hauv qab. Txawm li cas los xij, kev khiav hauj lwm tus nqi ntawm ob qho tib si sab sauv acetic acid thiab downstream ethyl thiab butyl ester cov lag luam feem ntau yog qis. Social cov khoom lag luam kuj feem ntau qis. Nrog rau kev txhim kho txuas ntxiv ntawm qhov kev xav tau nyob rau theem tom ntej, tus nqi qis qis ethyl ester, butyl ester thiab lwm yam khoom zoo li yuav nce maj mam.
