Mtengo wamsika wapakhomo wacyclohexanoneidatsika pakusinthasintha kwakukulu mu 2022, kuwonetsa mawonekedwe apamwamba kale komanso otsika pambuyo pake.Pofika pa Disembala 31, mwachitsanzo, potengera mtengo wobweretsera pamsika waku East China, mtengo wonsewo unali 8800-8900 yuan/tani, kutsika ndi 2700 yuan/ton kapena 23.38% kuchokera pa 11500-11600 yuan/ton nthawi yomweyi. chaka;Mtengo wotsika wapachaka unali 8700 yuan/tani, mtengo wapamwamba unali 12900 yuan/tani, ndipo mtengo wapachaka unali 11022.48 yuan/ton, kutsika kwa chaka ndi 3.68%.Makamaka, msika wa cyclohexanone udasinthasintha kwambiri theka loyamba la chaka.M'gawo loyamba la 2022, mtengo wa cyclohexanone udakwera wonse ndikukhazikika pamlingo wapamwamba.Chifukwa cha kukwera kwa benzene yoyera, mtengo wake umakhala wokhazikika.Kuphatikiza apo, zida za cyclohexanone zothandizira mabizinesi ake a lactam kumunsi kwa mtsinje ndizosazolowereka.Zogulitsazo zimakonzedwa Chikondwerero cha Spring chisanachitike, ndipo ulusi wamankhwala umadzazidwanso mwamphamvu.Msika wonse wa cyclohexanone uli pamtunda wapamwamba.Pambuyo pa Chikondwerero cha Spring, motsogozedwa ndi mafuta amitundu yonse, benzene yoyera idapitilirabe, zinthu zakumunsi za benzene yoyera zidakulitsidwa, ndipo unyolo wamakampani udayenda bwino.Kuphatikiza apo, kupezeka kwa cyclohexanone kwatsika, msika wakwera kwambiri, komanso kukwera ndi kugwa kwa intraday.M'mwezi wa Marichi, msika udakumana ndi kukana pang'onopang'ono, ndi kukwera ndi kugwa kwa mafuta osapsa.“Golidi, siliva ndi chachinayi” chobwera chifukwa cha mliriwo “chinaphonya kufunika kwamwambo.M'kanthawi kochepa, kusagwirizana pakati pa" kutulutsa kokhazikika "kwa cyclohexanone ndi caprolactam kumtunda ndi" kufuna kofooka "kwa nsalu zomaliza kudzakhala mutu waukulu.M'mwezi wa Meyi, ndikuwongolera mkhalidwe wa mliri komanso kukonza kufunikira kwa ma terminal, kuchuluka kwa phindu pamakina opanga mafakitale kwasintha.Pazifukwa zabwino zakutulutsidwa kwapang'onopang'ono kwa benzene yoyera, msika wa cyclohexanone udafika pachimake cha 12750 yuan/ton mchaka.
Mu theka lachiwiri la chaka, msika wa cyclohexanone unapitirizabe kuchepa.Mu Juni Ogasiti, mtengo wamtengo wapatali wa benzene yoyera unatsika kwambiri.Mu theka loyamba la chaka, chifukwa chakukula kwamphamvu kwatsopano kumtunda kwa benzene koyera komanso thandizo labwino la kuchepa kwamafuta amafuta amtundu wapadziko lonse ndi doko loyera la benzene, mtengo wa benzene udakwera njira yonse.Komabe, mu theka lachiwiri la chaka, zomwe zidakhudzidwa ndi kuchepa kwakukulu kwa mafuta osakhazikika padziko lonse lapansi komanso kutsika kwamadzi ndikuyamba, kufika kwa benzene ku East China kunakula.Msika weniweni wa benzene sukukweranso, ndipo mtengo ukutsika kwambiri.Panthawi imodzimodziyo, kufunikira kwa pansi kwa cyclohexanone kumakhala kofooka.Chifukwa cha kupezeka kokwanira, msika wa cyclohexanone wakhala ukugwa njira yonse, zomwe ndizovuta kulimbikitsa.Chifukwa cha kuchepa kwa mitengo, phindu lamakampani lidapitilirabe kutsika.Yangmei Fengxi, Shandong Haili, Jiangsu Haili, Luxi Oxidation Unit, Jining Bank of China ndi zigawo zina zamtengo wapatali zasiya kupanga kapena kuchepetsa kupanga.Kuchulukirachulukira kwa katundu wazinthu kunali kosakwana 50%, ndipo kupezeka kunachepa pang'onopang'ono.Pakufunidwa, caprolactam imakhala yokwanira, mankhwalawa atayika kwa nthawi yayitali, ndipo ntchito yonse yogwira ntchito ndi yotsika pafupifupi 65%.Inner Mongolia Qinghua, Heze Xuyang, Hubei Sanning, Zhejiang Juhua caprolactam magalimoto, Nanjing Dongfang, Baling Petrochemical, Tianchen ndi zipangizo zina sakhutitsidwa ndi chiyambi cha yomanga, ndi kunsi kwa mtsinje utoto, utoto, intermediates mankhwala ndi misika zina zosungunulira alinso mu. off-season.Kufunika kwa ulusi wamankhwala otsika ndi zosungunulira ndikotsika.Zida zina zokha za cyclohexanone oxidation zimawononga ndalama zambiri, ndipo cyclohexanone yaying'ono imakhala yovuta kukweza mtengo wamsika wa cyclohexanone.Kumapeto kwa Ogasiti, mtengo ku East China udatsika mpaka 9650 yuan/ton.
Mu Seputembala, msika wa cyclohexanone unakhazikika pang'onopang'ono ndikuwuka, makamaka chifukwa cha kukwera kwa msika wa benzene yaiwisi yaiwisi.Mtengo umathandizidwa bwino.The downstream self amide ikukwera pang'onopang'ono, ndipo ulusi wamankhwala umangofunika kutsatira.Mtengo wotsika wa cyclohexanone unagwa ndipo kuyang'ana kwa malonda kunakwera, motsogoleredwa ndi zinthu zabwino.Kuphatikiza apo, kufunikira kwa kuwonjezeredwa tsiku ladziko lisanachitike kunathandizira kukwera kwa msika.Pambuyo pa tchuthi cha National Day, idapitilira kuwuka.Chifukwa cha kukwera kwa misika yakunja, mitengo yamafuta amafuta ndi benzene yoyera idakwera.Mothandizidwa ndi mtengo wake, mtengo wa cyclohexanone unakwera pang'onopang'ono kufika pa 10850 yuan/ton.Komabe, pomwe zabwinozo zidachepa pang'onopang'ono, mitengo yamagetsi idatsika, miliri yapakhomo ndi yakumaloko idakulirakulira, kufunikira kwa msika kudatsika, ndipo msika udabwereranso.
Akuti mu 2023, ndi kukhathamiritsa kwa mfundo za mliri wapakhomo komanso chiyembekezo chabwino chachuma chambiri, kufunikira kwa msika wa cyclohexanone kukuyembekezeka kukwera.Komabe, m'zaka ziwiri zaposachedwa, pakhala pali mphamvu zambiri zopangira zatsopano, ndipo zida zambiri zatsopano zidzapangidwa m'tsogolomu, ndipo ntchito zambiri zothandizira caprolactam zidzapangidwa.Kachitidwe ka cyclohexanone caprolactam kagawo kaphatikizidwe kagawo kakuwoneka bwino kwambiri.Pankhani ya mtengo, popanda phindu lamphamvu kulimbikitsa kapena kusunga kachitidwe kosasunthika mumafuta amafuta akunja padziko lonse lapansi, benzene yoyera imakhalabe yovuta kubwezeretsanso, ndipo mtengo wa cyclohexanone umathandizidwa;Kuonjezera apo, kupanikizika kowonjezereka kwa makampani otsika a amide kudzawonekera pang'onopang'ono, ndipo mpikisano wamtengo wapatali wa msika wa cyclohexanone udzapitirira kuwonjezeka, ndipo udzakhala wochepa chifukwa cha kuwonongeka kwa nthawi yaitali kwa mafakitale.
