Ekuqaleni kuka-Ephreli, ngesonto elilodwa nje kuphela, intengo yemakethe ye-cyclohexanone yeqa ngo-900 yuan/ton. Kunezizathu eziningi zalokhu kugxuma. Ukuthi ukubukeka kwemakethe kungaqhubeka nokukhuphuka kukhathazwa imakethe.

Kusukela ngomhlaka-30 Mashi, intengo yemakethe ye-cyclohexanone ikhuphuke kakhulu. Intengo yemakethe ye-cyclohexanone eMpumalanga China ihlangabezane namagagasi amathathu okwenyuka isuka ku-9,450 yuan/ton. Kusukela ekupheleni kuka-Ephreli 7, intengo yemakethe ye-cyclohexanone eMpumalanga China ikhuphuke yafinyelela ku-10,350 yuan/ton. . Ngakho-ke ake sihlaziye ama-node esikhathi amagagasi amathathu alandelayo okunyuka kwentengo: igagasi lokuqala, ngoMashi 30, lenyuke ngo-200 yuan/ton. Isizathu sibangelwa ikakhulukazi ukutholakala okuqinile kwezimpahla emakethe. Ukunciphisa okukhipha nsuku zonke kukaShandong Hualu Hengsheng; Isitshalo saseChongqing Huafeng sivalwe ukuze silungiswe; Isitshalo se-Shanxi Yangmei Fengxi cyclohexanone sivaliwe futhi izindaba zokunakekela ziyasetshenziswa, ukuhanjiswa kwemakethe kuqiniswa, ukunikezwa kwefekthri kuyanqikaza ukuthengisa, futhi intengo ye-cyclohexanone emakethe yase-East China inyuke ngo-200 yuan / Ton yaya ku-9,650 yuan / ton; igagasi lesibili, Ephreli 1, ngokusho kukaZhuo Chuang Ulwazi, ukuthengiswa kweSinopec kwamanani asohlwini lwe-benzene ahlanzekile kukhuphuke ngo-150 yuan / ton, ukuqaliswa kwe-6,500 yuan / ton, futhi i-Fengxi yaqala ukukhuphula izindleko zesondlo. I-Eastern China i-cyclohexanone ikhuphuke ngama-yuan angama-300/ton yaya ku-9950; igagasi lesithathu, ngomhla ka-6 Ephreli, intengo yokufakwa kuhlu yokuthengiswa kwe-Sinopec ye-benzene emsulwa yaphinde yaphakanyiswa ngo-200 yuan/ton, kanye nokusetshenziswa kwe-6,700 yuan/ton, isimo sokuqina kwemakethe ngeke sishintshe, futhi izindleko zizosiza i-Push, intengo yemakethe ye-cyclohexanone ikhuphuke futhi, futhi intengo yemakethe ye-cyclohexanone eMpumalanga China ikhuphuke ngo-400 yuan/ton yaya ku-10,350 yuan/ton. Mayelana nenzuzo, umkhawulo wenzuzo we-cyclohexanone nawo usubuyile kulandela intengo. Kafushane, ukwenyuka kwentengo yemakethe ye-cyclohexanone ngakolunye uhlangothi kuhlobene nokusekelwa kwemakethe ye-benzene emsulwa, futhi ngakolunye uhlangothi, akunakuhlukaniswa nokusekelwa kwesidingo semakethe yefayibha yamakhemikhali.

Imakethe eyinhloko ye-caprolactam esezansi nomfula ye-cyclohexanone ibisebenza ezingeni eliphezulu, futhi iqhubekile nokuzinza ngaphezu kwama-85%. Isidingo sezinto zokusetshenziswa besiphezulu. Kodwa-ke, ingxenye yezimboni ezinkulu zokuthumela ngaphandle ze-cyclohexanone yalungiswa kabusha, futhi nokuhlinzekwa kokujikeleza kwemakethe kwaqiniswa.

Uma ubheka isimo semakethe, ngokombono wezindleko, ukufika kwe-benzene ehlanzekile ethekwini elikhulu kusenomkhawulo. Kusukela embikweni wokuthunyelwa kwemikhumbi, ichweba elikhulu lisaya endaweni yokugcina impahla. Ngokukhula kokulungiswa nokulungiswa ngo-Ephreli, umthwalo oqala embonini kulindeleke ukuthi wehle futhi. Ngasohlangothini lwesidingo, umthwalo wokuqala womkhakha we-styrene kulindeleke ukuthi wehle, kodwa ngemuva kokuthi iSinochem Quanzhou ne-China Sea Shell zifakwe ekukhiqizeni, isidingo sisonke sinyukile. Ngakho-ke, i-benzene emsulwa isesebhalansi eqinile, futhi kufanele kuqashelwe umthelela wezitayela ze-styrene emakethe. Kusukela ohlangothini lokuhlinzeka, ukugcinwa kwe-Huafeng kulindeleke ukuthi kuphele esikhathini esizayo esiseduze, futhi ukugcinwa kwedivayisi ye-Yangmei Fengxi kulindeleke ukuthi kuhlale okungenani izinsuku ezingu-20, futhi kulindeleke ukuthi kuqale kabusha ukukhiqizwa komthwalo ogcwele ngemva kokuphela kukaMeyi; idivayisi ye-Hualu Hengsheng ilayishiwe futhi isikhathi sokutakula kufanele sinqunywe. Ngokwesidingo, isitshalo sesibili se-caprolactam sikaShandong Haili kuhlelelwe ukuthi siqale ngo-Ephreli 10 (esisekelayo). Kusukela ngomhlaka-15 Ephreli, i-Cangzhou Xuyang Chemical's caprolactam ihlelelwe ukuthi ilungiswe kabusha cishe izinsuku eziyi-10 (isekelwa), futhi ngo-April 20, iFujian Yongrong Technology, iNanjing Dongfang yama ngokulandelana ukuze ilungiswe kabusha, futhi yalungiswa kabusha izinsuku eziyi-7 nezinsuku ezingama-40 ngokulandelana. Ngaphezu kwalokho, cishe ngo-Ephreli 20, u-Yangmei Fengxi kulindeleke ukuthi aqale umthwalo ophansi ukuze agcwalise kabusha imakethe. Kulindeleke ukuthi ukunikezwa okuqinile kwe-cyclohexanone kuzoqhubeka okungenani kuze kube ngu-Ephreli 20 futhi kuqale ukudamba. Ngakho-ke, ngamafuphi, i-cyclohexanone Ukuthambekela okukhuphukayo kwamanani emakethe kuzohlala okungenani kuze kube sekupheleni kuka-April, futhi ulinde futhi ubone umthelela wezinguquko kumakethe ye-benzene ehlanzekile ku-cyclohexanone.
