Ixabiso lemarike yasekhaya yecyclohexanoneyehle kuguquko oluphezulu ngo-2022, ebonisa ipateni ephezulu ngaphambi naphantsi emva kwayo. Ukususela kwi-31 kaDisemba, ukuthatha ixabiso lokuhanjiswa kwimarike ye-East China njengomzekelo, uluhlu lwexabiso jikelele lwaluyi-8800-8900 yuan / ton, phantsi kwe-2700 yuan / ton okanye i-23.38% ukusuka kwi-11500-11600 yuan / ton ngexesha elifanayo kunyaka odlulileyo; Ixabiso eliphantsi lonyaka laliyi-8700 yuan / ton, ixabiso eliphezulu laliyi-12900 yuan / ton, kwaye ixabiso eliqhelekileyo lonyaka laliyi-11022.48 yuan / ton, ukuhla konyaka-ngonyaka kwe-3.68%. Ngokukodwa, imakethi ye-cyclohexanone iye yaguquguquka kakhulu kwisiqingatha sokuqala sonyaka. Kwikota yokuqala ye-2022, ixabiso le-cyclohexanone lenyuka lilonke kwaye emva koko lahlala kwinqanaba eliphezulu. Ngenxa yokunyuka kwe-benzene ecocekileyo, inkxaso yeendleko izinzile. Ukongeza, izixhobo ze-cyclohexanone ezixhasa amashishini ayo e-lactam kumazantsi omlambo aziqhelekanga. Iimveliso zilungiswa ngaphambi koMthendeleko weNtwasahlobo, kwaye imicu yeekhemikhali izaliswa ngamandla. Imarike ye-cyclohexanone iyonke ikwicala eliphezulu. Emva koMnyhadala weNtwasahlobo, phantsi kwesikhokelo se-oyile ekrwada yamazwe ngamazwe, i-benzene ecocekileyo yaqhubeka iphinda ibuyele, iimveliso ezisezantsi zebenzene ecocekileyo zonyuswa, kwaye ikhonkco leshishini liqhube kakuhle. Ukongezelela, ukunikezelwa kwe-cyclohexanone kunciphile, imarike inyuke ngokukhawuleza, kwaye kukho ukunyuka kwe-intraday kunye nokuwa. Ngo-Matshi, imarike ngokuthe ngcembe yadibana nokuchasana, kunye nokunyuka kunye nokuwa kweoli ekrwada. "Igolide, isilivere kunye neyesine" ebangelwa ngubhubhane "yayiphosa imfuno yemveli. Ngexesha elifutshane, ukuchasana phakathi" kwemveliso ezinzileyo "ye-cyclohexanone enyukayo kunye ne-caprolactam kunye" nemfuno ebuthathaka "yempahla ye-terminal iya kuba ngumxholo ophambili. NgoMeyi, kunye nolawulo lwemeko yobhubhane kunye nokulungiswa kwenqanaba lee-terminal ezifunwayo, inzuzo yokukhululwa kwe-terminal iphuculwe. imfuno kunye neempembelelo eziphezulu ze-benzene ecocekileyo, imarike ye-cyclohexanone ifike kwincopho ye-12750 yuan/ton ngonyaka.
Kwisiqingatha sesibini sonyaka, imarike ye-cyclohexanone yaqhubeka iyancipha. NgoJuni ka-Agasti, ixabiso lendawo ye-benzene ecocekileyo yehle kakhulu. Kwisiqingatha sokuqala sonyaka, ngenxa yokukhula okukhawulezayo komthamo omtsha wemveliso yebenzene esulungekileyo kunye nenkxaso encomekayo yokwehla kweoli ekrwada yamazwe ngamazwe kunye noluhlu lwe-benzene port ecocekileyo, ixabiso le-benzene ecocekileyo lenyuka yonke indlela. Nangona kunjalo, kwisiqingatha sesibini sonyaka, esichatshazelwe kukuhla okuphezulu kwe-oyile ekrwada kumazwe ngamazwe kunye nemfuno esezantsi yomlambo kunye nokuqala, ukufika kwe-benzene ecocekileyo e-East China kwanda. Imarike ye-benzene ecocekileyo ayisakhuphuki, kwaye ixabiso lehla ngokukhawuleza. Ngexesha elifanayo, imfuno esezantsi ye-cyclohexanone ibuthathaka. Ngenxa yobonelelo olwaneleyo, imakethi ye-cyclohexanone iye yawa yonke indlela, ekunzima ukuyinyusa. Ngokuhla kwamaxabiso, iingeniso zenkampani ziqhubekile nokuhla. Yangmei Fengxi, Shandong Haili, Jiangsu Haili, Luxi Oxidation Unit, Jining Bank of China kunye nezinye iiyunithi umthamo mveliso ziyeka imveliso okanye ukunciphisa imveliso. Umthamo wokusebenza uwonke womthamo wempahla yorhwebo ubungaphantsi kwama-50%, kwaye unikezelo lwehla ngokuthe ngcembe. Ngokwemfuno, i-caprolactam inokubonelela ngokwaneleyo, imveliso ilahlekelwe yilahleko yexesha elide, kwaye umthwalo wokusebenza jikelele uphantsi malunga ne-65%. I-Inner Mongolia Qinghua, Heze Xuyang, Hubei Sanning, Zhejiang Juhua caprolactam parking, Nanjing Dongfang, Baling Petrochemical, Tianchen kunye nezinye izixhobo abanelisekanga ngokuqalwa kokwakhiwa, kunye nepeyinti esezantsi, ipeyinti, i-pharmaceutical intermediates kunye nezinye iimarike zokunyibilikisa nazo kwi-off-season. Imfuno yefiber yeekhemikhali esezantsi kunye ne-solvent imbi kakhulu. Kuphela ezinye izixhobo ze-cyclohexanone oxidation zibiza ngaphezulu, kwaye inani elincinci le-cyclohexanone kusenzima ukunyusa ixabiso lemarike ye-cyclohexanone. Ekupheleni kuka-Agasti, ixabiso eMpuma yeChina lawela kwi-9650 yuan / ton.
NgoSeptemba, imakethi ye-cyclohexanone yazinza kwaye yavuka, ikakhulu ngenxa yokunyuka kwentengiso ye-benzene ecocekileyo. Iindleko zixhaswa kakuhle. I-self amide esezantsi inyuka ngokuthe ngcembe, kwaye ifayibha yemichiza ifuna ukulandelwa kuphela. Ixabiso eliphantsi le-cyclohexanone lawa kwaye ukugxila kokuthengiselana kwaphakama, kuqhutywe yimeko efanelekileyo. Ukongezelela, imfuno yokuzaliswa kwakhona ngaphambi koSuku lweSizwe luxhase ukunyuka kokugxila kwimarike. Emva kweholide yoSuku lweSizwe, yaqhubeka inyuka. Ngenxa yokunyuka ngokubanzi kweemarike zaphesheya, amaxabiso eoyile ekrwada kunye nebenzene esulungekileyo enyuke. Ixhaswa yindleko, ixabiso le-cyclohexanone ngokuthe ngcembe lanyuka ukuya kwi-10850 yuan/ton. Nangona kunjalo, njengoko i-positive isiya ngokuthe ngcembe, amaxabiso amandla ehla, ubhubhani wasekhaya nowasekhaya waphinda wanda, imfuno yentengiso yehla, kunye nentengiso yabuyela umva.
Kuqikelelwa ukuba ngo-2023, ngokulungiswa komgaqo-nkqubo wobhubhane wasekhaya kunye nolindelo oluhle lwe-macro-economy, imfuno yemarike ye-cyclohexanone kulindeleke ukuba inyuke. Nangona kunjalo, kwiminyaka emibini yakutshanje, kukho amandla amaninzi okuvelisa amatsha, kwaye inani elikhulu lezixhobo ezitsha ziya kufakwa kwimveliso kwixesha elizayo, kwaye ezininzi iiprojekthi ze-caprolactam ezixhasayo ziya kufakwa kwimveliso. Umkhwa wokudityaniswa kwesilayi se-cyclohexanone caprolactam uya ucaca ngakumbi. Ngokwendleko, ngaphandle kweengeniso eziqinileyo zokukhuthaza okanye ukugcina i-trend eguquguqukayo kwi-oyile ekrwada yamazwe ngamazwe, i-benzene ecocekileyo kusenzima ukuyibuyisela, kwaye ixabiso le-cyclohexanone lixhaswa ngokubanzi; Ukongezelela, uxinzelelo olugqithisileyo lwe-industrial amide esezantsi luya kubonakala ngokuthe ngcembe, kwaye uxinzelelo lwexabiso lokhuphiswano lwe-cyclohexanone lwemarike luya kuqhubeka nokunyuka, kwaye luya kunqunyulwa ngokulahleka kwexesha elide kwishishini.
