1.Tshaj tawm ntawm cov dej ntwsacetic acidkev lag luam sib txawv

Tus nqi nruab nrab ntawm acetic acid thaum pib ntawm lub hli yog 3235.00 yuan / ton, thiab tus nqi thaum kawg ntawm lub hli yog 3230.00 yuan / ton, nce 1.62%, thiab tus nqi yog 63.91% qis dua xyoo tas los.

Thaum lub Cuaj Hlis, kev lag luam acetic acid tau tswj hwm los ntawm ntau yam oscillations, nrog cov nqi poob ua ntej nce.Nyob rau hauv thawj ib nrab ntawm lub xyoo, lub lag luam acetic acid nyob rau hauv consolidation, nrog txaus mov, txwv downstream thov, tsis muaj zog ua lag luam mov thiab thov, acetic acid nqi fluctuated;Nyob rau hauv lub thib ob ib nrab ntawm lub xyoo, lub lag luam acetic acid tsis muaj zog thiab downward, feem ntau vim hais tias cov acetic acid txij nkawm cov lag luam rov pib ua hauj lwm ib txwm, cov khoom lag luam txaus txaus, cov khoom qis qis qis qis, cov khoom muaj zog thiab tsis muaj zog, acetic. acid nqi txuas ntxiv mus;Thaum kawg ntawm lub hli, Hnub So Hnub Nyoog tau los txog, qhov kev thov qis qis rau cov khoom lag luam nce ntxiv, thiab cov lag luam muaj lub siab xav nce nqi.Thaum kawg ntawm lub hli, qhov kev thov tau nce mus, ua raws li cov nqi methanol nce siab, cov khoom siv raw khoom txhawb nqa tau zoo, qhov kawg ntawm lub hli acetic acid nqi tau nce mus txog ze rau thaum pib ntawm lub hli.

2. ethyl acetate kev lag luam kev tsom xam

Nyob rau lub Cuaj Hli, domestic ethyl acetate tseem tsis muaj zog, kev ua lag luam tseem nyob rau hauv tus txheej txheem ntawm bottoming tawm.Raws li Kev Lag Luam Xov Xwm Kev Tshawb Fawb Kev Tshawb Fawb, qhov poob ntawm lub hlis no yog 0.43%, thiab nyob ze rau lub hli kawg, tus nqi lag luam ntawm ethyl acetate yog 6700-7000 yuan / ton.

Lub hlis no, tus nqi ntawm ethyl acetate tsis zoo npaum li cas, acetic acid feem ntau ntawm lub hli oscillating downward, lub lim tiam kawg ntawm lub Cuaj hli rebounded, ua rau ib tug luv luv lub sij hawm ntawm ethyl acetate nce, lub kawg ntawm lub hlis yuav tsis tau sustained, cov nqi tseem tsis tau rov qab mus rau qhov pib ntawm qib.Muaj kev hloov pauv me ntsis ntawm cov khoom siv, feem ntau ntawm cov nroj tsuag nyob rau sab hnub tuaj Tuam Tshoj tau ua haujlwm ib txwm, thiab cov tuam txhab xa khoom lub zog tsis tau ua rau lub caij nyoog siab tshaj plaws ntawm "Golden Nine", thiab cov khoom muag tseem siab.Tag nrho cov kev hloov pauv ntawm tus nqi twv ntawm cov nroj tsuag loj hauv Shandong tsis yog qhov tseem ceeb.Lub downstream tsis muaj zog ntawm kev ua lag luam yog qhov nyuaj rau kev txhim kho, thiab kev yuav khoom tseem ruaj khov tsuas yog xav tau.

3.butyl acetate kev lag luam kev tsom xam

Hauv tsev butyl acetate txuas ntxiv poob rau lub Cuaj Hli, thiab kev lag luam tseem tsis muaj zog.Raws li Kev Lag Luam Newswire, qhov poob ntawm butyl acetate txhua hli yog 2.37%.Thaum kawg ntawm lub hlis, tus nqi ntawm domestic butyl acetate yog 7,200-7,500 yuan / ton.

Ntawm ib sab, tus nqi sib txawv, txawm hais tias acetic acid rebounded thaum kawg ntawm lub hli, tab sis tseem nyuaj rau tsav cov downstream butyl acetate tawm ntawm qhov tsaus ntuj, lwm cov khoom ntws ntws n-butanol poob qis, nqis 2.91% hauv lub hli. .Zuag qhia tag nrho, tus nqi sab tseem yog dominated los ntawm sab luv.Lub sij hawm ntev kev ntxhov siab ntawm butyl acetate feem ntau yog los ntawm kev siab ntawm cov khoom siv thiab kev thov: qhov pib ntawm cov khoom siv, butyl cov lag luam pib tus nqi hloov me ntsis, tus nqi pib ntawm cov nroj tsuag loj los tswj lub siab thiab qis dua 40%, tab sis cov khoom lag luam siab ntawm cov nroj tsuag loj yog pom tseeb, nyob rau hauv qhov kev xav tau tsis muaj zog, kev lag luam kev lag luam tsis zoo.Lub davhlau ya nyob twg tswj tsuas yog xav tau, thiab tag nrho kev lag luam huab cua yog lub teeb.

4.Kev soj ntsuam ntawm cov acetic acid kev lag luam saw

Los ntawm daim ntawv sib piv ntawm kev nce thiab poob ntawm cov acetic acid kev lag luam saw, peb tuaj yeem pom tias kev lag luam saw pom ib qho kev sib txawv ntawm qhov txias ntawm sab saum toj thiab kub hauv qab, nrog methanol (19.17%) ntawm qhov kawg ntawm kev nce siab, tso siab rau acetic acid thiab cov dej ntws qis.Hauv particular, downstream ethyl ester thiab butyl ester tseem tsis pub dawb los ntawm kev ua lag luam tsis zoo.Cov nyiaj rov qab ntawm cov lag luam nyob rau lub hli tseem khaws cov nqi pib ntawm qhov qis, nrog rau qhov tsis zoo ntawm cov kua dej feem ntau.

Nyob rau lub sijhawm luv luv, acetic acid kev lag luam cov saw hlau yuav ua kom tsis muaj zog, cov tuam txhab acetic acid tuaj yeem khaws cov khoom lag luam thaum lub caij so, tab sis cov khoom lag luam hauv qab ntawm ethyl acetate, butyl acetate thiab PTA txuas ntxiv tau noj thaum lub caij ua koob tsheej, thiab kev ua lag luam ntxiv tom qab. kev ua koob tsheej yuav coj cov txiaj ntsig rau acetic acid.Txawm li cas los xij, xav txog qhov kev txhim kho me ntsis hauv qhov kawg thov.Ethyl ester thiab butyl ester tus nqi yuav nyob twj ywm tsis muaj zog.

Chemwinyog lub tuam txhab tshuaj raw khoom lag luam nyob hauv Suav teb, nyob hauv Shanghai Pudong New Area, nrog lub network ntawm cov chaw nres nkoj, cov chaw nres nkoj, tshav dav hlau thiab kev tsheb ciav hlau thauj mus los, thiab nrog cov khoom siv tshuaj lom neeg thiab phom sij hauv Shanghai, Guangzhou, Jiangyin, Dalian thiab Ningbo Zhoushan, Suav. , khaws cia ntau tshaj 50,000 tons ntawm cov khoom siv raw khoom txhua xyoo, nrog cov khoom txaus, txais tos yuav thiab nug.chaw email:service@skychemwin.comwhatsapp: 19117288062 Tel: +86 4008620777 +86 19117288062
