NgoDisemba, imarike ye-acetate ye-butyl yayikhokelwa yindleko. Ixabiso le-acetate ye-butyl e-Jiangsu kunye ne-Shandong yayahlukile, kwaye umahluko wexabiso phakathi kwezi zibini zehla kakhulu. Ngomhla we-2 kaDisemba, umahluko wexabiso phakathi kwezi zibini wawuyi-yuan eyi-100 kuphela. Ngexesha elifutshane, phantsi kwesikhokelo sezinto ezisisiseko kunye nezinye izinto, kulindeleke ukuba umehluko wexabiso phakathi kwezi zibini unokubuyela kuluhlu olufanelekileyo.

Njengenye yezona ndawo ziphambili zemveliso ye-butyl acetate e-China, i-Shandong inokuhamba okubanzi kwempahla. Ukongeza ekuzisebenziseni kwendawo, i-30% - 40% yemveliso iphinda igeleze ukuya eJiangsu. Umahluko ophakathi wexabiso phakathi kweJiangsu kunye neShandong ngo-2022 uya kugcina isithuba se-arbitrage se-200-300 yuan/ton.

Ukusukela ngo-Okthobha, ingeniso yethiyori yemveliso ye-acetate ye-butyl e-Shandong nase-Jiangsu ngokusisiseko ayidlulanga kwi-400 yuan/ton, apho i-Shandong iphantsi kakhulu. NgoDisemba, inzuzo yokuvelisa i-butyl acetate yehla, kubandakanywa malunga ne-220 yuan / toni e-Jiangsu kunye ne-150 yuan / ton e-Shandong.

Umahluko kwinzuzo ikakhulu ngenxa yokwahlukana kwexabiso le-n-butanol ekubunjweni kweendleko zeendawo ezimbini. Ukuveliswa kwetoni enye ye-acetate ye-butyl idinga iitoni ze-0.52 ze-acetic acid kunye ne-0.64 yeetoni ze-n-butanol, kwaye ixabiso le-n-butanol liphezulu kakhulu kune-acetic acid, ngoko ke i-n-butanol inomlinganiselo obalulekileyo kwiindleko zokuvelisa. i-butyl acetate.

Njenge butyl acetate, umahluko wexabiso le-n-butanol phakathi kweJiangsu kunye neShandong uzinzile ixesha elide. Kwiminyaka yakutshanje, ngenxa yokuguquguquka kwezinye izityalo ze-n-butanol kwiPhondo laseShandong kunye nezinye izinto, uluhlu lwezityalo kule ndawo luyaqhubeka luphantsi kwaye ixabiso liphezulu, nto leyo eyenza imveliso yethiyori inzuzo ye-butyl acetate kwiPhondo laseShandong. iphantsi ngokubanzi, kwaye ukuzimisela kwabavelisi abaphambili ukuqhubeka nokwenza iingeniso kunye nokuthumela ngenqanawa kuphantsi kwaye ixabiso liphezulu ngokwentelekiso.

Ngenxa yomahluko kwiingeniso, imveliso yeShandong kunye neJiangsu nayo yahlukile. NgoNovemba, inani elipheleleyo le-butyl acetate laliyi-53300 tons, ukunyuka kwe-8.6% ngenyanga ngenyanga kunye ne-16.1% ngonyaka.

Emantla eTshayina, imveliso yancitshiswa kakhulu ngenxa yeendleko. Isiphumo senyanga sisonke sasimalunga neetoni ezingama-8500, phantsi kwe-34% ngenyanga,

Imveliso eMpuma yeChina yayimalunga neetoni ze-27000, i-58% ngenyanga ngenyanga.

Ngokusekwe kwisikhewu esicacileyo kwicala lonikezelo, umdla weefektri ezimbini zothutho nawo awuhambelani.

Kwixesha elizayo, utshintsho olupheleleyo lwe-n-butanol alubalulekanga phantsi kwemvelaphi ye-inventory ephantsi, ixabiso le-acetic acid lingaqhubeka nokuhla, uxinzelelo lweendleko ze-acetate ye-butyl lunokuthi lube buthathaka kancinci, kwaye ukunikezelwa kwe-Shandong kulindeleke ukuba Nyusa. I-Jiangsu kulindeleke ukuba inciphise ukubonelela kwayo ngenxa yomthwalo ophezulu wokwakha kwinqanaba lokuqala kunye nokugaya okukhulu kwixesha elizayo. Ngaphantsi kwemvelaphi engentla, kulindeleke ukuba umehluko wexabiso phakathi kweendawo ezimbini uya kubuyela ngokuthe ngcembe kwinqanaba eliqhelekileyo.
