Kubva muhafu yechipiri yegore, kwave nekutsauka kwakakosha mumaitiro e-n-butanol uye ayo ane hukama zvigadzirwa, octanol uye isobutanol.Kupinda mukota yechina, chiitiko ichi chakaenderera mberi uye chakakonzera nhevedzano yezvakazoitika, zvichibatsira nenzira isina kunanga kudiwa kwen-butanol, ichipa rutsigiro rwakanaka rwekuchinja kwayo kubva pakuderera kweunilateral kuenda kune imwe nzira.

Mukutsvaga kwedu kwemazuva ese uye kuongororwa kwen-butanol, zvigadzirwa zvine hukama ndizvo zvakakosha zvinotaridza zviratidzo.Pakati pezvigadzirwa zviripo zvine hukama, octanol uye isobutanol zvine mhedzisiro yakakosha pan-butanol.Muchikamu chechipiri chegore, pakanga paine musiyano mukuru wemutengo pakati peoctanol nen-butanol, nepo isobutanol yakaramba yakakwira kupfuura n-butanol.Chiitiko ichi chave nekukanganisa kukuru pakupihwa uye kudiwa chimiro chen-butanol, uye chave nekukanganisa maitiro en-butanol muchikamu chechina.

Kubva pachikamu chechina, zvichibva pakutariswa kwedhata rekushandisa pasi, takaona kuti chiyero chekushanda kwechigadzirwa chikuru chepasi, butyl acrylate, chadzikira zvakanyanya, zvichikonzera kudzikira kwakanyanya mukudiwa kwen-butanol.Nekudaro, zvichipesana nemamiriro ekuwedzera ekuwedzera, musika unotarisira kuti n-butanol indasitiri chain ikurumidze kuunganidza inventory mune ramangwana, zvichikonzera kuviriswa kwebearish manzwiro.Muchirevo chechinyorwa chino, musika wen-butanol wakaona kudzikira kwepamusoro pe2000 yuan/ton.Zvisinei, tarisiro dzisina simba muchokwadi dzakasangana nechokwadi chakasimba, uye kushanda chaiko kwemusika wen-butanol munaNovember kwakatsauka zvakanyanya kubva pane zvaitarisirwa kare.Kutaura zvazviri, pasinei nekushayikwa kwekutsigirwa kwepamusoro kwekushanda kubva kune yakakura yakadzika pasi butyl acrylate, kuwedzera kwehuwandu hwekushanda kwezvimwe zvigadzirwa zvepasi zvakadai sebutyl acetate uye DBP inokosha zvikuru, iyo inotsigira maitiro ezvino e-n-butanol kubva kune unilateral kuderera kusvika kumativi. oparesheni.Kubva pakupera kwaNovember 27, mutengo weShandong n-butanol waive pakati pe7700-7800 yuan/ton, uye wanga uchitengesera padivi padanho iri kwemavhiki matatu akateedzana.

Kune dudziro dzakawanda dzekuchinja kwekushandiswa kwepasi nemusika, asi kuwedzera kwemitengo yekushanda kweindasitiri yepasi peplasticizer DBP indasitiri uye inoenderera yakaderera inventory mamiriro ezvinhu anopokana nemaitiro echinyakare eindastiri panguva yemwaka wepamusoro.Isu tinotenda kuti kuitika kwechiitiko chiri pamusoro chine hukama kwete chete nedanho rekuzadzazve pasi pemvura, asiwo kune zvigadzirwa zvine hukama, uye zvine chekuita nemusika wen-butanol.

Musiyano wemutengo uri kuwedzera pakati peoctanol nen-butanol zvisina kunanga unowedzera kudiwa kwen-butanol.

Mumakore mashanu apfuura (2018-2022), avhareji yemutengo musiyano pakati peoctanol nen-butanol yaive 1374 yuan/ton.Kana uyu mutsauko wemutengo ukapfuura kukosha uku kwenguva yakareba, zvinogona kutungamira kumidziyo inoshanduka kusarudza kuwedzera octanol kugadzirwa kana kuderedza n-butanol kugadzirwa.Nekudaro, kubvira 2023, musiyano wemutengo uyu wakaramba uchiwedzera, uchisvika pa3000-4000 yuan/ton muchikamu chechitatu nechina.Uyu mutsauko wakanyanya wemutengo wepamusoro wakwezva zvishandiso zvinoshanduka kusarudza kugadzira n-butanol, nekudaro zvichikanganisa rutivi rwekudiwa kwen-butanol.

Nekuwedzera kwemusiyano wemutengo pakati peoctanol nen-butanol, zviitiko zvakakosha zvekutsiva zvakabuda mundima yepasi peplasticizer.Kunyange zvazvo chikamu cheDBP mumunda weplasticizers hachina kukosha, sezvo kusiyana kwemutengo pakati pe octanol ne n-butanol kunowedzera, mutengo wepakati pakati peDBP ne octanol plasticizers unoramba uchiwedzera.Zvichienderana nemitengo yemitengo, vamwe vatengi vekupedzisira vakawedzera zvine mwero kushandiswa kweDBP, zvisina kunanga kuwedzera kudyiwa kwen-butanol, nepo huwandu hunoenderana hweoctanol plasticizers hwakaderera.

Isobutanol inoramba ichikwira kupfuura n-butanol, iine kumwe kudiwa kuchinjika kuenda kun-butanol

Kubva pachikamu chechitatu, mutsauko wemutengo pakati pen-butanol uye isobutanol wakachinja zvakanyanya.Nerutsigiro rwayo rwakasimba rwakakosha, isobutanol yachinja zvishoma nezvishoma kubva pakuva yakaderera pane n-butanol kusvika pakukwirira kupfuura n-butanol semazuva ese, uye musiyano wemutengo pakati pezviviri wasvika pakakwirira patsva mumakore achangopfuura.Uku kushanduka kwemutengo kwakave nemhedzisiro yakakura pakushandiswa kweisobutanol/n-butanol.Sezvo mutengo wekushandisa isobutanol plasticizers uchidzikira, vamwe vatengi vari pasi pemvura vari kugadzirisa mafomula avo ekugadzira uye kutendeukira kuDBP nemutengo wakakura wakanakira.Kubva pachikamu chechitatu, mafekitori akati wandei eisobutanol plasticizer kuchamhembe nekumabvazuva kweChina akasangana nekuderera kwakasiyana kwemitengo yekushanda, mamwe mafekitori achitochinja kugadzira n-butanol plasticizers, zvichisimudzira kudyiwa kwen-butanol.
