Kusukela engxenyeni yesibili yonyaka, kube nokuphambuka okukhulu emvemeni we-N-Butanol nemikhiqizo yayo ehlobene, i-Octanol ne-Isobutanol. Ukufaka ikota yesine, le nto yaqhubeka futhi yaqamba uchungechunge lwemithelela elandelayo, izuze ngokungaqondile uhlangothi lwe-N-Butanol, ukuhlinzeka ngokusekelwa okuhle ngoguquko lwalo kusuka ekunciphiseni okungekho emqondweni.

Ocwaningweni lwethu lwansuku zonke kanye nokuhlaziywa kwe-N-Butanol, imikhiqizo ehlobene yizinkomba zesithenjwa ezibalulekile. Phakathi kwemikhiqizo ehlobene ekhona, i-Octanol ne-Isobutanol abanomthelela omkhulu ku-N-Butanol. Engxenyeni yesibili yonyaka, kwakukhona umehluko omkhulu wentengo phakathi kwe-Octanol ne-N-Butanol, kuyilapho i-IsoButanol yahlala iphakeme ngokungaguquki kune-N-Butanol. Lesi simo sibe nomthelela omkhulu ekuhlinzekweni kanye nesakhiwo se-N-Butanol, futhi sibe nomthelela ekuthambekeni kwe-N-Butanol kwikota yesine.

Kusukela ikota yesine, esekelwe ekubhekweni kwemininingwane esebenza phansi yomfula, sithole ukuthi izinga lokusebenza lomkhiqizo omkhulu we-townstream, i-acrylate enkulu, ukuncipha kakhulu, okuholela enkambisweni ephakeme ephansi ekufunweni kwe-N-Butanol. Kodwa-ke, ngokumelene ne-wackrop yokuhlinzekwa okwandayo, imakethe ilindele ukuthi i-N-Buthanol Ikhambo Ikata ukuze liqongelele ngokushesha ukusungula ngokuzayo, kubangele ukuvutshelwa kwemizwa yomugqa. Kulesi simo, imakethe ye-N-Butanol ithole ukwehla okungaphezulu kuka-2000 yuan / ton. Kodwa-ke, okulindelwe okubuthakathaka ngokweqiniso kuhlangane namaqiniso anamandla, futhi ukusebenza kwangempela kwemakethe ye-N-Butanol ngoNovemba kuphambuka kakhulu kusuka ekulindelweni kwangaphambilini. Eqinisweni, naphezu kokuntuleka kokuxhaswa okuphezulu okuphezulu kusuka ku-acrylate enkulu kakhulu ye-towstream acrylate, ukwanda kwamanani okusebenza kweminye imikhiqizo engezansi efana ne-BUTYL acetate ne-DBP kubaluleke kakhulu, okusekela ukwehla kwamanje kwe-N-Butanol kusuka emaceleni ukusebenza. Njengoba kusondele ngoNovemba 27, intengo kaShandong N-Butanol yayiphakathi kuka-7700-7800 yuan / ithoni, futhi ibilokhu ithengisa eceleni kwaleli zinga ngasemaviki amathathu alandelanayo.

Kunokutolika okuningi kwezinguquko ekusetshenzisweni kwe-Downstream ngemakethe, kepha ukwanda kwamanani okusebenza kwe-Dowstream Plistic Plistic DBP Industry kanye nesimo esiphikelelayo sokusungula siyaphikisana nokusebenza kwendabuko komkhakha ngesikhathi senduna. Sikholwa ukuthi ukwenzeka kwalesi simo esingenhla kuhlobene kakhulu hhayi kuphela ekugcwaliseni okugcwele kwe-Downstream, kodwa nakumikhiqizo ehlobene nemakethe ye-N-Butanol.

Umehluko wentengo ebanzi phakathi kwe-Octanol ne-N-Buthanol ngokungaqondile kwandisa ngokuqondile isidingo se-N-Butanol

Eminyakeni emihlanu edlule (2018-2022), umehluko wentengo ojwayelekile phakathi kwe-Octanol ne-N-Butanol kwakungu-1374 Yuan / Ton. Lapho umehluko wentengo umehluko weqa leli nani isikhathi eside, kungahle kuholele kumadivayisi aguqukayo akhetha ukukhulisa ukukhiqizwa kwe-octanol noma ukunciphisa ukukhiqizwa kwe-n-Butanol. Kodwa-ke, kusukela ngonyaka we-2023, umehluko wentengo uqhubeke nokunweba, ukufinyelela ku-3000-4000 yuan / ithoni endaweni yesithathu neyesine. Lo mehluko omkhulu wentengo ephezulu uhehe amadivaysi aguqukayo ukukhetha ukukhiqiza i-n-Butanol, ngaleyo ndlela ethinta uhlangothi lwe-N-Butanol.

Ngokwanda komehluko wentengo phakathi kwe-Octanol ne-N-Buthanol, izehlakalo ezibalulekile zokufaka esikhundleni sezivele ziqhamuke ensimini yezondlalishi ezansi. Yize ingxenye ye-DBP emkhakheni wamapulasitiki ayibalulekile, njengoba umehluko wentengo phakathi kwe-Octanol ne-N-Butanol enweba, umehluko wentengo phakathi kwe-DBP ne-Octanol Ngokusekelwe ekucabangeni kwezindleko, amanye amakhasimende okugcina akhuphule ngokulinganayo ukusetshenziswa kwe-DBP, ngokungaqondile ukusetshenziswa kokusetshenziswa kwe-N-Butanol, ngenkathi inani elihambisanayo lamapulasitiki e-octanol sehle.

I-Isobutanol iyaqhubeka nokuba ngaphezulu kwe-n-Butanol, ngesidingo esithile esiguqukayo ku-N-Butanol

Kusukela ikota yesithathu, umehluko wentengo phakathi kwe-N-Butanol ne-Isobutanol esenze ushintsho olukhulu. Ngokusekelwa kwayo okuyisisekelo okuqinile, i-isobaSol iguqukile kancane kancane ukusuka ngaphansi kwe-n-butanol ekubeni iphakeme kune-n-butanol njengenjwayelo, futhi umehluko wentengo phakathi kwalaba bobabili usufinyelele phezulu okusha eminyakeni yamuva. Lokhu kuguquguquka kwentengo sekube nomthelela omkhulu ekusetshenzisweni kwe-isobatol / n-Butanol. Njengoba inzuzo yezindleko zamapulasitiki e-isobutanol iyancipha, amanye amakhasimende aphansi alungisa amafomula abo okukhiqiza futhi aguqukele ku-DBP ngezinzuzo ezinkulu zezindleko. Kusukela ikota yesithathu, amafektri ambalwa e-Isobutanol Plastic enyakatho nasempumalanga yeChina ake abhekana namazinga ahlukahlukene okuncipha kwamanani okusebenza, amafektri athile aphenduke akhiqize i-N-Butanol.
