Engxenyeni yokuqala ka-2022, imakethe ye-isopropanol iyonke yayibuswa ukushaqeka kwamazinga aphansi amaphakathi.Uma sithatha imakethe ye-Jiangsu njengesibonelo, intengo yemakethe emaphakathi engxenyeni yokuqala yonyaka ibingu-7343 yuan/ton, ikhuphuke ngo-0.62% ngenyanga futhi yehle ngo-11.17% unyaka nonyaka.Phakathi kwazo, intengo ephakeme kakhulu yayiyi-8000 yuan/ton, eyavela phakathi no-March, intengo ephansi kakhulu yayiyi-7000 yuan/ton, futhi yabonakala engxenyeni engezansi ka-April.Umehluko wentengo phakathi kokuphela okuphezulu nokuphela okuphansi bekuyi-yuan eyi-1000/ton, ne-amplitude engu-14.29%.
I-amplitude yokuguquguquka kwesikhawu ikhawulelwe

Engxenyeni yokuqala ka-2022, imakethe ye-isopropanol izokhombisa ngokuyisisekelo inkambiso yokukhuphuka kuqala bese yehla, kepha isikhala sokuguquguquka silinganiselwe.Kusukela ngoJanuwari kuya maphakathi noMashi, imakethe ye-isopropanol yakhuphuka ngokushaqeka.Ekuqaleni koMkhosi Wasentwasahlobo, umsebenzi wokuhweba emakethe wehla kancane kancane, ama-oda okuhweba ayevame ukulinda futhi ubone, futhi intengo yemakethe ngokuyisisekelo yashintsha phakathi kuka-7050-7250 yuan/ton;Ngemuva kokubuya kuMkhosi Wasentwasahlobo, imakethe ye-acetone ne-propylene ekhuphukayo ikhuphuke ngamazinga ahlukahlukene, okwenza umdlandla wezitshalo ze-isopropanol ukhule.Ukugxila kwezingxoxo zemakethe ye-isopropanol yasekhaya kukhuphuke ngokushesha kwafinyelela ku-7500-7550 yuan/ton, kodwa imakethe kancane kancane yabuyela ku-7250-7300 yuan/ton ngenxa yokubuyiswa kokuvilapha kwesidingo esibulalayo;NgoMashi, isidingo sokuthumela ngaphandle sasinamandla.Ezinye izitshalo ze-isopropanol zathunyelwa echwebeni, futhi intengo yangaphambili kawoyela ongahluziwe we-WTI yadlula ngokushesha u-$120/umphongolo.Ukunikezwa kwezitshalo ze-isopropanol kanye nemakethe kwaqhubeka nokukhula.Ngaphansi komqondo wokuthenga we-downstream, inhloso yokuthenga yanda.Maphakathi noMashi, imakethe ikhuphuke yafinyelela ezingeni eliphezulu lika-7900-8000 yuan/ton.Kusukela ngoMashi kuze kube sekupheleni kuka-Ephreli, imakethe ye-isopropanol iqhubekile nokwehla.Ngakolunye uhlangothi, iyunithi ye-isopropanol ye-Ningbo Juhua yakhishwa ngempumelelo futhi yathunyelwa kwamanye amazwe ngoMashi, futhi ibhalansi yokunikezwa kwemakethe nesidingo yaphulwa futhi.Ngakolunye uhlangothi, ngo-April, umthamo wezokuthutha wesifunda wehla, okwaholela ekuncipheni kancane kancane kwesidingo sohwebo lwangaphakathi.Eduze kuka-Ephreli, intengo yemakethe yehle yabuyela ezingeni eliphansi lika-7000-7100 yuan/ton.Kusukela ngoMeyi kuya kuJuni, imakethe ye-isopropanol yayibuswa ukushaqeka kwebanga elincane.Ngemuva kokwehla okuqhubekayo kwentengo ngo-Ephreli, abanye basekhayaisopropyl utshwalaamayunithi avalwa ukuze alungiswe, futhi intengo yemakethe yaqiniswa, kodwa isidingo sasekhaya sasiphansi.Emuva kokuphothulwa kwesitoko sokuthekelisa, intengo yemakethe ikhombise ukukhuphuka okunganele.Kulesi sigaba, uhla lokusebenza olujwayelekile lwemakethe bekungu-7200-7400 yuan/ton.
Ukuthambekela okukhulayo kokunikezwa okuphelele kuyabonakala, futhi isidingo sokuthumela ngaphandle siyaphinda siphinde sibuyele

Mayelana nokukhiqizwa kwasekhaya: Iyunithi ye-Ningbo Juhua engu-50000 t/a isopropanol yakhiqizwa ngempumelelo futhi yathunyelwa kwamanye amazwe ngoMashi, kodwa ngesikhathi esifanayo, iyunithi ye-Dongying Haike engu-50000 t/a isopropanol iye yahlakazwa.Ngokwendlela yokusebenza yeZhuochuang Information, yasuswa kumthamo wokukhiqiza we-isopropanol, okwenza umthamo wasekhaya we-isopropanol uzinze kumathani ayizigidi eziyi-1.158.Mayelana nomkhiqizo, isidingo sokuthumela kwamanye amazwe engxenyeni yokuqala yonyaka sasilungile, futhi umphumela wabonisa inkambiso ekhuphukayo.Ngokwezibalo zeZhuochuang Information, engxenyeni yokuqala ka-2022, ukuphuma kwe-isopropanol yaseChina kuzoba amathani angama-255900, okuwukukhula kwamathani angama-60000 unyaka nonyaka, ngesilinganiso sokukhula esingu-30.63%.
Izinto ezithunyelwa ngaphandle: Ngenxa yokwenyuka kokuhlinzekwa kwangaphakathi kanye nensalela yokuhlinzekwa kwezidingo zasekhaya kanye nesidingo, umthamo wokungenisa ukhombisa ukwehla.Kusukela ngoJanuwari kuya kuJuni 2022, inani eliphelele lokungeniswa kwe-isopropyl utshwala eChina lalicishe libe ngamathani ayi-19300, ukwehla konyaka nonyaka ngamathani angama-2200, noma i-10.23%.
Mayelana nokuthunyelwa kwempahla kwamanye amazwe: Okwamanje, ingcindezi yokuhlinzekwa kwasekhaya ayinciphi, futhi amanye amafekthri asathembele ekwehliseni isidingo sokuthekelisa ukuze kutholakale ingcindezi yezimpahla.Kusukela ngoJanuwari kuya kuJuni 2022, inani eliphelele lokuthunyelwa kwe-isopropanol eChina lizoba amathani angama-89300, okuwukunyuka kwamathani angama-42100 noma ama-89.05% unyaka nonyaka.
Inzuzo ephelele kanye nokwehlukaniswa kwesivuno senqubo ekabili

Ngokusho kokubalwa kwemodeli yenzuzo eyingqikithi ye-isopropanol, inzuzo enkulu yethiyori yenqubo ye-acetone hydrogenation isopropanol engxenyeni yokuqala ka-2022 izoba ngu-603 yuan/ton, 630 yuan/ton ngaphezu kwenkathi efanayo ngonyaka odlule, ephakeme ngo-2333.33% kune-2333.33% isikhathi esifanayo ngonyaka odlule;Inzuzo eyingqikithi yethiyori yenqubo ye-propylene hydration isopropanol yayingu-120 yuan/ton, 1138 yuan/ton ngaphansi kwaleyo yenkathi efanayo ngonyaka odlule, iphansi ngo-90.46% kunaleyo yenkathi efanayo ngonyaka odlule.Kungabonakala eshadini lokuqhathanisa lenzuzo eyisamba yezinqubo ezimbili ze-isopropanol ukuthi ngo-2022, inkambiso yethiyori yenzuzo eyingqikithi yezinqubo ezimbili ze-isopropanol izohlukaniswa, izinga lenzuzo eyingqikithi yenqubo ye-acetone hydrogenation lizozinza, futhi isilinganiso senzuzo yanyanga zonke ngokuyisisekelo sizoguquguquka ku-500-700 yuan/ton, kodwa inzuzo ecatshangelwayo ye-propylene hydration process yake yalahlekelwa cishe amayuan angama-600/ton.Uma kuqhathaniswa nezinqubo ezimbili, inzuzo yenqubo ye-acetone hydrogenation isopropanol ingcono kunenqubo ye-propylene hydration.
Kusukela kudatha yokukhiqizwa kwe-isopropanol kanye nesidingo eminyakeni yamuva nje, izinga lokukhula kwesidingo sasekhaya alizange lihambisane nesivinini sokunwetshwa kwamandla.Endabeni yokuthengiswa ngokweqile kwesikhathi eside, inzuzo yethiyori yezitshalo ze-isopropanol isibe yisici esiyinhloko esinquma izinga lokusebenza.Ngo-2022, inzuzo enkulu yenqubo ye-acetone hydrogenation isopropanol izoqhubeka ibe ngcono kunaleyo ye-propylene hydration, okwenza ukukhishwa kwesitshalo se-acetone hydrogenation isopropanol kube phezulu kakhulu kunokwe-propylene hydration.Ngokusho kokuqapha idatha, engxenyeni yokuqala ka-2022, ukukhiqizwa kwe-isopropanol nge-acetone hydrogenation kuzoba ngu-80.73% wengqikithi yokukhiqiza kazwelonke.
Gxila ohlangothini lwezindleko nesidingo sokuthekelisa engxenyeni yesibili yonyaka
Engxenyeni yesibili ka-2022, ngokombono wokuhlinzeka nokufunwa okuyisisekelo, ayikho iyunithi entsha ye-isopropanol efakwe emakethe njengamanje.Umthamo we-isopropanol wasekhaya uzohlala emathani ayizigidi ezingu-1.158, futhi ukukhishwa kwasekhaya kusazokhiqizwa ikakhulukazi inqubo ye-acetone hydrogenation.Ngokukhuphuka kwengozi yokuntengantenga komnotho emhlabeni jikelele, isidingo sokuthunyelwa kwe-isopropanol sizoba buthakathaka.Ngasikhathi sinye, isidingo setheminali yasekhaya sizolulama kancane, noma isimo "senkathi ephezulu asiphumeleli" sizokwenzeka.Engxenyeni yesibili yonyaka, ingcindezi yokuhlinzeka nokufunwa izohlala ingashintshiwe.Ngokombono wezindleko, uma kucatshangelwa ukuthi izitshalo ezintsha ze-phenol ketone zizosetshenziswa engxenyeni yesibili yonyaka, ukuhlinzekwa kwemakethe ye-acetone kuzoqhubeka kudlula isidingo, futhi intengo ye-acetone njengoba impahla eluhlaza ephezulu izoqhubeka. ukushintshashintsha ezingeni eliphansi elimaphakathi;Engxenyeni yesibili yonyaka, ethintwe inqubomgomo yokwenyuka kwezinga lenzalo ye-Federal Reserve kanye nobungozi bokuwohloka komnotho eYurophu nase-United States, isikhungo somfutho wamanani kawoyela wamazwe ngamazwe singase sehle.Uhlangothi lwezindleko luyisici esiyinhloko esithinta amanani e-propylene.Amanani emakethe ye-propylene engxenyeni yesibili yonyaka azokwehla uma kuqhathaniswa nengxenye yokuqala yonyaka.Ngamafuphi, ingcindezi yezindleko zamabhizinisi e-isopropanol kunqubo ye-acetone hydrogenation ayinkulu okwamanje, futhi ukucindezeleka kwezindleko zamabhizinisi e-isopropanol kunqubo ye-propylene hydration kulindeleke ukuba kudambe, kodwa ngesikhathi esifanayo, ngenxa yokuntuleka kokuphumelela. ukwesekwa ngezindleko, amandla aphindayo emakethe ye-isopropanol nawo awanele.Kulindeleke ukuthi imakethe ye-isopropanol igcine iphethini yokushaqeka kwesikhashana engxenyeni yesibili yonyaka, inake inkambiso yentengo ye-acetone ekhuphuka nomfula kanye noshintsho lwesidingo sokuthekelisa.
