Intengo yemakethe yasekhaya yei-cyclohexanoneyehle ekuguquguqukeni okuphezulu ngo-2022, ikhombisa iphethini yokuphezulu ngaphambi naphansi ngemuva.Kusukela ngomhla ka-31 Disemba, uma sithatha intengo yokulethwa emakethe yase-East China njengesibonelo, ububanzi bentengo bebuyi-8800-8900 yuan/ton, lehle ngo-2700 yuan/ton noma u-23.38% ukusuka ku-11500-11600 yuan/ton esikhathini esifanayo sokugcina. unyaka;Intengo ephansi yonyaka ibingu-8700 yuan/ton, intengo ephezulu ibingu-12900 yuan/ton, kanti intengo emaphakathi yonyaka ibingu-11022.48 yuan/ton, ukwehla konyaka nonyaka ngo-3.68%.Ngokukhethekile, imakethe ye-cyclohexanone iguquguquke kakhulu engxenyeni yokuqala yonyaka.Ngekota yokuqala ka-2022, intengo ye-cyclohexanone yenyuka iyonke bese yazinza ezingeni eliphezulu.Ngenxa yokukhuphuka kwe-benzene ehlanzekile, ukusekelwa kwezindleko kuzinzile.Ngaphezu kwalokho, imishini ye-cyclohexanone esekela amabhizinisi ayo e-lactam endaweni engezansi yomfula ayijwayelekile.Imikhiqizo ilungiswa ngaphambi koMkhosi Wasentwasahlobo, futhi imicu yamakhemikhali igcwaliswa ngamandla.Imakethe ye-cyclohexanone iyonke isohlangothini oluphezulu.Ngemuva koMkhosi waseNtwasahlobo, ngaphansi kokuqondisa kukawoyela ongahluziwe wamazwe ngamazwe, i-benzene ehlanzekile yaqhubeka nokuphindaphinda, imikhiqizo engaphansi komfula ye-benzene emsulwa yathuthukiswa, futhi uchungechunge lwezimboni lwaqhuba kahle.Ngaphezu kwalokho, ukunikezwa kwe-cyclohexanone kwehlile, imakethe ikhuphuke kakhulu, futhi kukhona nokukhuphuka nokuwa kwe-intraday.NgoMashi, imakethe kancane kancane yabhekana nokuphikiswa, ngokukhuphuka nokuwa kukawoyela ongahluziwe.“Igolide, isiliva nokwesine” okwabangelwa ubhadane “laphuthelwa isidingo esivamile.Esikhathini esifushane, ukungqubuzana phakathi” kokuphuma okuzinzile “kwe-cyclohexanone ekhuphuka nomfula kanye ne-caprolactam kanye” nesidingo esibuthakathaka “sezindwangu zokugcina kuzoba itimu eyinhloko.NgoMeyi, ngokulawulwa kwesimo sobhubhane kanye nokulungiswa kwesidingo esibulalayo, izinga lenzuzo yochungechunge lwezimboni liye laba ngcono.Ngaphansi kwezinto ezivumayo zokukhishwa kwesidingo ngezigaba kanye nomthelela ophezulu we-benzene emsulwa, imakethe ye-cyclohexanone ifike ku-12750 yuan/ton ngonyaka.
Engxenyeni yesibili yonyaka, imakethe ye-cyclohexanone yaqhubeka nokwehla.NgoJuni Agasti, intengo yendawo ye-benzene ehlanzekile yehla kakhulu.Engxenyeni yokuqala yonyaka, ngenxa yokukhula ngokushesha komthamo omusha wokukhiqiza we-benzene ehlanzekile kanye nokwesekwa okuhle kokwehla kwamafutha angahluziwe emhlabeni wonke kanye nenani lechweba le-benzene elihlanzekile, intengo ye-benzene emsulwa yenyuka yonke indlela.Kodwa-ke, engxenyeni yesibili yonyaka, ethintwe ukwehla okukhulu kwamafutha ongahluziwe emhlabeni wonke kanye nesidingo esisezansi nomfula kanye nokuqala, ukufika kwe-benzene ehlanzekile eMpumalanga China kukhule.Imakethe ye-benzene emsulwa ayisakhuli, futhi intengo yehla ngokushesha.Ngesikhathi esifanayo, isidingo esingezansi somfula se-cyclohexanone sibuthakathaka.Ngenxa yokuhlinzekwa okwanele, imakethe ye-cyclohexanone ibilokhu iwa yonke indlela, okunzima ukuyikhulisa.Ngokuncipha kwamanani, inzuzo yezinkampani iqhubekile nokwehla.I-Yangmei Fengxi, i-Shandong Haili, i-Jiangsu Haili, i-Luxi Oxidation Unit, i-Jining Bank yase-China namanye amayunithi evolumu yempahla amise ukukhiqiza noma ukunciphisa ukukhiqizwa.Umthamo ophelele wokusebenza womthamo wempahla ubungaphansi kwama-50%, futhi ukunikezwa kwehle kancane kancane.Mayelana nesidingo, i-caprolactam itholakala ngokwanele, umkhiqizo ulahlekelwe isikhathi eside, futhi umthwalo wokusebenza jikelele uphansi cishe ngo-65%.I-Inner Mongolia Qinghua, Heze Xuyang, Hubei Sanning, Zhejiang Juhua caprolactam parking, Nanjing Dongfang, Baling Petrochemical, Tianchen nezinye izinto zokusebenza azinelisekile ngokuqala kokwakhiwa, futhi upende ongezansi, upende, i-intermediate yemithi nezinye izimakethe ze-solvent nazo zikhona. I-off-season.Isidingo se-fiber yamakhemikhali esezansi nomfula kanye ne-solvent siphansi.Imishini ethile ye-cyclohexanone oxidation kuphela ibiza ngaphezulu, futhi inani elincane le-cyclohexanone kusenzima ukukhulisa intengo yemakethe ye-cyclohexanone.Ekupheleni kuka-Agasti, intengo eMpumalanga China yehle yaya ku-9650 yuan/ton.
NgoSepthemba, imakethe ye-cyclohexanone kancane kancane yazinza futhi yaphakama, ikakhulukazi ngenxa yokukhuphuka kwemakethe ye-benzene eluhlaza.Izindleko zisekelwa kahle.I-self amide engezansi ikhuphuka kancane kancane, futhi i-chemical fiber idinga ukulandelwa kuphela.Intengo ephansi ye-cyclohexanone yehla futhi ukugxila kokuthengiselana kwakhuphuka, kuqhutshwa isimo esihle.Ngaphezu kwalokho, isidingo sokugcwaliswa kabusha ngaphambi koSuku LukaZwelonke sisekele ukukhuphuka kokugxila emakethe.Ngemva kweholide Losuku Lwesizwe, laqhubeka nokukhuphuka.Ngenxa yokwenyuka okujwayelekile kwezimakethe zaphesheya kwezilwandle, amanani kawoyela ongahluziwe kanye ne-benzene emsulwa akhuphuka.Isekelwe yizindleko, intengo ye-cyclohexanone kancane kancane yenyuka yaya ku-10850 yuan/ton.Kodwa-ke, njengoba okuhle kuncipha kancane kancane, amanani kagesi ehla, izifo eziwumshayabhuqe zasekhaya nezasekhaya zaphindeka, isidingo sezimakethe sehla, nemakethe yehla.
Kulinganiselwa ukuthi ngo-2023, ngokusetshenziswa kahle kwenqubomgomo yobhubhane lwasekhaya kanye nokulindela okuhle komnotho omkhulu, isidingo semakethe ye-cyclohexanone kulindeleke ukuthi sikhuphuke.Kodwa-ke, eminyakeni emibili yamuva nje, kube namandla amaningi okukhiqiza amasha, futhi inani elikhulu lemishini emisha lizofakwa ekukhiqizeni esikhathini esizayo, futhi amaphrojekthi amaningi e-caprolactam asekelayo azofakwa ekukhiqizeni.Ukuthambekela kokuhlanganiswa kwe-cyclohexanone caprolactam slice kuya kuba sobala kakhulu.Ngokwezindleko, ngaphandle kwenzuzo eqinile yokukhuthaza noma ukugcina ukuthambekela okuguquguqukayo kuwoyela ongahluziwe wamazwe ngamazwe, i-benzene ehlanzekile kusenzima ukuyibopha kabusha, futhi izindleko ze-cyclohexanone ngokuvamile ziyasekelwa;Ukwengeza, ukucindezela okweqile kwemboni ye-amide engezansi kuzovela kancane kancane, futhi ukucindezela kokuncintisana kwamanani emakethe ye-cyclohexanone kuzoqhubeka nokukhula, futhi kuzonqunywa ukulahlekelwa isikhathi eside kwemboni.
