Posachedwapa, mankhwala ambiri ku China achulukirachulukira, zinthu zina zikuwonjezeka ndi 10%.Uku ndikuwongolera kobwezera pambuyo pakuchepa kwapang'onopang'ono kwa pafupifupi chaka koyambirira, ndipo sikunakonzeretu kutsika kwa msika.M'tsogolomu, msika wa mankhwala aku China udzakhalabe wofooka kwa nthawi yayitali.
Octanol imagwiritsa ntchito acrylic acid ndi gasi kaphatikizidwe ngati zopangira, vanadium monga chothandizira kupanga butyraldehyde yosakanikirana, yomwe n-butyraldehyde ndi Isobutyraldehyde amayengedwa kuti apeze n-butyraldehyde ndi isobutyraldehyde, kenako octanol imapezeka kudzera mu shrinkage hydrogenation, rectification ndi njira zina.Mtsinje wapansi umagwiritsidwa ntchito makamaka m'munda wa plasticizers, monga dioctyl terephthalate, dioctyl Phthalic acid, isooctyl acrylate, etc. TOTM/DOA ndi madera ena.
Msika waku China uli ndi chidwi kwambiri ndi octanol.Kumbali imodzi, kupanga octanol kumayendera limodzi ndi kupanga zinthu monga butanol, zomwe zimakhala zamagulu angapo ndipo zimakhala ndi msika waukulu;Kumbali inayi, monga chinthu chofunikira cha plasticizers, chimakhudza mwachindunji msika wa ogula pulasitiki.
M'chaka chathachi, msika wa octanol waku China wasintha kwambiri mitengo, kuyambira 8650 yuan/ton mpaka 10750 yuan/ton, ndi 24.3%.Pa June 9, 2023, mtengo wotsika kwambiri unali 8650 yuan/ton, ndipo mtengo wapamwamba kwambiri unali 10750 yuan/ton pa February 3, 2023.
M'chaka chatha, mtengo wamsika wa octanol wasintha kwambiri, koma matalikidwe apamwamba ndi 24% okha, omwe ndi otsika kwambiri kusiyana ndi kuchepa kwa msika waukulu.Kuonjezera apo, mtengo wamtengo wapatali m'chaka chapitacho unali 9500 yuan / tani, ndipo pakali pano msika wadutsa mtengo wamtengo wapatali, zomwe zimasonyeza kuti ntchito yonse ya msika ndi yolimba kuposa mlingo wapakati pa chaka chatha.
Chithunzi 1: Mtengo Wamtengo Wamsika wa Octanol ku China M'chaka Chatha (Chigawo: RMB/ton)

Pakadali pano, chifukwa chamtengo wamtengo wapatali wamsika wa octanol, phindu lonse lopanga octanol limatsimikiziridwa kukhala lapamwamba kwambiri.Malinga ndi mtengo wa propylene, msika wa octanol waku China wakhalabe ndi phindu lalikulu chaka chatha.Pafupifupi phindu la msika waku China wa octanol ndi 29%, ndi phindu lalikulu pafupifupi 40% ndi phindu lochepera 17%, kuyambira Marichi 2022 mpaka Juni 2023.
Zitha kuwoneka kuti ngakhale mitengo yamsika yatsika, kupanga octanol kudakali pamlingo wapamwamba.Poyerekeza ndi zinthu zina, kuchuluka kwa phindu la octanol ku China ndikwambiri kuposa kuchuluka kwazinthu zama mankhwala ambiri.
Chithunzi 2: Kusintha kwa Phindu la Octanol ku China pa Chaka Chapita (Chigawo: RMB/ton)

Zifukwa zopangira phindu la octanol nthawi zonse ndi izi:
Choyamba, kuchepa kwa ndalama zopangira zinthu kumakhala kwakukulu kwambiri kuposa kwa octanol.Malinga ndi ziwerengero, propylene ku China idatsika ndi 14.9% kuyambira Okutobala 2022 mpaka June 2023, pomwe mitengo ya octanol idakwera ndi 0.08%.Chifukwa chake, kuchepa kwamitengo yazinthu zopangira kwadzetsa phindu lochulukirapo la octanol, chomwe chilinso chifukwa chachikulu chowonetsetsa kuti phindu la octanol likhalebe lokwera.
Kuchokera mu 2009 mpaka 2023, kusinthasintha kwamitengo ya propylene ndi octanol ku China kunawonetsa chizolowezi chokhazikika, koma msika wa octanol unali ndi matalikidwe okulirapo komanso kusakhazikika kwa msika wa propylene kunali kokhazikika.Malingana ndi kuyesedwa kovomerezeka kwa deta, mlingo woyenera wa kusinthasintha kwamitengo m'misika ya propylene ndi octanol ndi 68.8%, ndipo pali mgwirizano wina pakati pa ziwirizi, koma mgwirizanowu ndi wofooka.
Kuchokera pazithunzi zomwe zili pansipa, zikuwoneka kuti kuyambira Januware 2009 mpaka Disembala 2019, kusinthasintha ndi matalikidwe a propylene ndi octanol zinali zosagwirizana.Kuchokera pazomwe zikugwirizana ndi deta panthawiyi, kugwirizana pakati pa ziwirizi kuli pafupi ndi 86%, kusonyeza kugwirizana kwakukulu.Koma kuyambira 2020, octanol yakula kwambiri, yomwe ndi yosiyana kwambiri ndi kusinthasintha kwa propylene, chomwenso ndi chifukwa chachikulu cha kuchepa koyenera pakati pa ziwirizi.
Kuyambira 2009 mpaka June 2023, mitengo ya octanol ndi propylene ku China idasinthasintha (gawo: RMB/ton)

Kachiwiri, m'zaka zaposachedwa, mphamvu zatsopano zopangira pamsika wa octanol ku China zakhala zochepa.Malinga ndi deta yoyenera, kuyambira 2017, sipanakhale zida zatsopano za octanol ku China, ndipo mphamvu zonse zopangira zidakhalabe zokhazikika.Kumbali imodzi, kukula kwa sikelo ya octanol kumafuna kutenga nawo gawo pakupanga gasi, komwe kumalepheretsa mabizinesi ambiri atsopano.Kumbali ina, kukula kwapang'onopang'ono kwamisika yotsika mtengo kwapangitsa kuti msika wa octanol usayendetsedwe ndi kufunikira.
Poganizira kuti kuchuluka kwa kupanga octanol ku China sikukukulirakulira, kupezeka ndi kufunikira kwa msika wa octanol kwachepa, ndipo mikangano yamisika siinawonekere, yomwe imathandiziranso phindu lopanga msika wa octanol.
Mitengo ya msika wa octanol kuyambira 2009 mpaka pano yasintha kuchoka pa 4956 yuan/ton kufika pa 17855 yuan/ton, ndi kusinthasintha kwakukulu, zomwe zikuwonetsanso kusatsimikizika kwakukulu kwamitengo yamsika ya octanol.Kuyambira 2009 mpaka June 2023, mtengo wapakati wa octanol pamsika waku China udachokera pa 9300 yuan/ton mpaka 9800 yuan/ton.Kuwonekera kwa ma inflection angapo m'mbuyomu kukuwonetsanso kuthandizira kapena kukana kwamitengo yapakati pa octanol kusinthasintha kwa msika.
Pofika mu June 2023, mtengo wapakati pa msika wa octanol ku China unali 9300 yuan pa tani imodzi, zomwe zili mkati mwamitengo yapakati pazaka 13 zapitazi.Mbiri yotsika mtengo ndi 5534 yuan/ton, ndipo inflection point ndi 9262 yuan/ton.Ndiko kunena kuti, ngati mtengo wa msika wa octanol ukupitirirabe kutsika, malo otsika angakhale chithandizo chazomwe zimatsika.Ndi kubwezeredwa ndi kukwera kwamitengo, mtengo wake wapakati pa 9800 yuan/tani ukhoza kukhala mulingo wokana kukwera kwamitengo.
Kuchokera mu 2009 mpaka 2023, mtengo wa octanol ku China umasintha (gawo: RMB/ton)


Mu 2023, China idzawonjezera zida zatsopano za octanol, zomwe zidzaphwanya mbiri ya zida zatsopano za octanol m'zaka zingapo zapitazi ndipo zikuyembekezeka kukulitsa mkhalidwe woipa pamsika wa octanol.Komanso, poyembekezera kufooka kwanthawi yayitali pamsika wamankhwala, zikuyembekezeka kuti mitengo ya octanol ku China ikhalabe yofooka kwa nthawi yayitali, zomwe zitha kukakamiza phindu pamlingo wapamwamba.
