Ukususela kwisiqingatha sesibini sonyaka, kuye kwakho ukuphambuka okukhulu kwimo ye-N-butanol kunye neemveliso ezinxulumene noko, i-octanol kunye nesobutanol. Ukungena kwikota yesine, le phethonon yaqhubeka kwaye yabangela uthotho lweempembelelo ezilandelayo, ukuzuza ngokungathanga ngqo kwi-N-B-Butanol, ukubonelela ngenkxaso elungileyo kuhlaselo lwayo lokungasebenzi.

Kuphando lwethu lwemihla ngemihla kunye nohlalutyo lwe-N-Butanol, iimveliso ezinxulumene noko ziyimpawu eziphambili zereferensi. Phakathi kweemveliso ezinxulumene noko, i-octanol kwaye isobutanol inefuthe elibalulekileyo kwi-N-Butanol. Kwisiqingatha sesibini sonyaka, kukho umahluko obalulekileyo wexabiso phakathi kwe-octanol kunye ne-N-B-butanol, ngelixa isobutanol bahlala bephezulu ngakumbi kuno-N-Butanol. Le phengnomenon inefuthe elibonakalayo kulwakhiwo kunye ne-akhawunti ye-N-butanol, kwaye inefuthe kwimo ye-N-butanol kwikota yesine.

Ukusukela kwikota yesine, esekwe ekujongasweni kwedatha yokusebenza esezantsi, sifumanise ukuba inqanaba lokusebenza kwemveliso enkulu ye-Dowstream, i-Byyl Acrylate, ekhokelela ekubalekeni kwe-N-Butanol. Nangona kunjalo, ngokuchasene ne-backdrop yokwanda kokunikezelwa, imarike ilindele ukuba i-N-B-Bhaanol yeShishini le-N-B-Bsheonol yeShishini ukuze iqokelele ngokukhawuleza i-inventri kwixesha elizayo, ininzi ukubongoza ukubonakala kwengqondo. Kule meko, imakethi ye-N-B-Butanol ivele ukuhla kwe-2000 yuan / ton. Nangona kunjalo, ukulindela okubuthathaka kwenyani kuye kwahlangabezana nenyaniso eyomeleleyo, kwaye eyona ntsebenzo yemakethi ye-N-B-B-butanol ngo-Novemba yaphanziswa kakhulu kulindelo lwangaphambili. Ngapha koko, ngaphandle kokunqongophala kwenkxaso ephezulu yokusebenza evela kwelona lungelo liphezulu le-Bywl Acrylate, ukunyuka kwamaxabiso e-Dowl Lowream efana ne-N-BOCANoL ye-N-BOANOL YOKUGQIBELA YOKUGQIBELA ukusebenza. Njengakulo hlobo nge-27 kaNovemba, ixabiso le-Shandong N-Bhananol laliphakathi kwe-7700-7800 Yuan / Ton, kwaye yayithengiwe ecaleni kweeveki ezintathu ezilandelelanayo.

Kukho ukutolikwa okuninzi kotshintsho kwi-dowstream putoting Putuxtream Piector, kodwa ukunyuka kwamaxabiso okusebenza kwe-Dowplerlizer i-DOWP ye-DOWP ye-DOWP ye-DOWP kunye nendawo eqhubekayo ye-onventri. Sikholelwa ukuba ukuvela kwento engasentla inxulumene ngokusondeleyo kuphela kwi-Downkhash yoPhezulu, kodwa nakwiimveliso ezinxulumene noko, kwaye inefuthe elizinzileyo kwimarike ye-N-B-Bsheanol.

Umahluko wamaxabiso awongezelekileyo phakathi kwe-octanol kunye ne-N-B-Butanol ngokungathanga ngqo kwimfuno ye-N-butanol

Kule minyaka mihlanu idlulileyo (2018-2022), umahluko wamaxabiso ophakathi phakathi kwe-octanol kunye ne-N-Bhananol yayingu-1374 Yuan / Ton. Xa lo mahluko amaxabiso angaphezulu kwexabiso ixesha elide, kunokukhokelela kwizixhobo eziguqukayo ukukhetha ukwandisa imveliso ye-octanol okanye inciphise imveliso ye-N-B-blanol. Nangona kunjalo, ukusukela ngonyaka wama-2023, lo mahluko amaxabiso uqhubekile, efikelela kwi-3000-4000 yuan / ton kwikota yesithathu neyesine. Lo mahluko uphela ugqithisileyo unomdla kwizixhobo eziguqukayo ezinokukhetha ukuvelisa i-N-Butanol, ngaloo ndlela ichaphazela icala le-N-butanol.

Ngokwandiswa komahluko wamaxabiso phakathi kwe-octanol kunye ne-N-B-butanol, i-phenomenation ye-phenomena ivele kwintsimi yeplastiki esezantsi. Nangona i-DBP ye-DBP kwicandelo leplastiki alibalulekanga, njengoko umahluko wamaxabiso phakathi kwe-Octanol iyanda, umahluko wamaxabiso phakathi kwe-DBP kunye ne-Octanol Phambili ikwandisa rhoqo. Ngokusekwe kwiintelekelelo zeendleko, abanye abaThengi banyuse ngokulinganayo ukusetyenziswa kwe-DBP, ngokungathanga ngqo ukuselwa kwe-N-butanol, ngelixa inani elihambelanayo le-octanol linciphile.

Isobutanol iyaqhubeka nokuba iphezulu kune-N-Butanol, kunye nemfuno ethile eguqukayo kwi-N-butanol

Ukusukela kwikota yesithathu, umahluko wamaxabiso phakathi kwe-N-Butanol kwaye isobutanol iphumelele utshintsho olubalulekileyo. Ngenkxaso yayo esisiseko, isobutanol itshintshwe ngokuthe ngcembe ekubeni ingaphantsi kwe-N-Butanol ukuba ingaphezulu kwe-N-Butanol njengesiqhelo, kwaye umahluko wamaxabiso phakathi kweminyaka emibini sele ifikile kwiminyaka entsha. Esi siqinisekiso sexabiso sinefuthe elibonakalayo ekusetyenzisweni kwesobutanol / n-butanol. Njengoko indleko zexabiso le-isobutanol incipha, abanye abathengi abaphantsi bahlengahlengisa iifomula zabo zemveliso kwaye baguqukele kwi-DBP enezinto ezinkulu zexabiso. Ukusukela kwikota yesithathu, iifektri ze-isobutanol ze-isobutanol e-North naseMpuma ye-China zinamava ahlukeneyo kwi-capritings esebenzayo, kunye neefektri ze-b-bheanol, ngokungathanga ngqo kwi-N-Bhananol.
