NgoDisemba, imakethe ye-butyl acetate yayiqondiswa izindleko. Umkhuba wamanani we-butyl acetate e-Jiangsu naseShandong wawuhlukile, futhi umehluko wentengo phakathi kwakho kokubili wehle kakhulu. Ngomhla zi-2 kuZibandlela, umehluko wentengo phakathi kwalokhu kokubili ubungamayuan ayi-100/ton. Esikhathini esifushane, ngaphansi kokuqondiswa kwezinto eziyisisekelo nezinye izici, kulindeleke ukuthi umehluko wentengo phakathi kwakho kokubili ungabuyela ebangeni elinengqondo.

Njengenye yezindawo eziyinhloko zokukhiqiza ze-butyl acetate e-China, i-Shandong inokugeleza okubanzi kwezimpahla. Ngokungeziwe ekuzisebenziseni kwendawo, u-30% - 40% womkhiqizo nawo ugelezela eJiangsu. Umehluko omaphakathi wamanani phakathi kwe-Jiangsu ne-Shandong ngo-2022 ngokuyisisekelo uzogcina isikhala se-arbitrage esingu-200-300 yuan/ton.

Kusukela ngo-Okthoba, inzuzo yokukhiqizwa kwethiyori ye-butyl acetate e-Shandong nase-Jiangsu ngokuyisisekelo ayikadluli ku-400 yuan/ton, lapho i-Shandong iphansi kakhulu. NgoDisemba, yonke inzuzo yokukhiqiza ye-butyl acetate yehla, okuhlanganisa cishe ama-yuan/ton angama-220 e-Jiangsu kanye no-150 yuan/ton e-Shandong.

Umehluko enzuzweni ikakhulukazi ngenxa yomehluko wentengo ye-n-butanol ekubunjweni kwezindleko zalezi zindawo ezimbili. Ukukhiqizwa kwethani elilodwa le-acetate ye-butyl kudinga amathani angu-0.52 e-acetic acid namathani angu-0.64 we-n-butanol, futhi intengo ye-n-butanol iphakeme kakhulu kune-acetic acid, ngakho-ke i-n-butanol inengxenye ebalulekile ezindlekweni zokukhiqiza. i-butyl acetate.

Njenge-butyl acetate, umehluko wentengo we-n-butanol phakathi kwe-Jiangsu ne-Shandong uzinzile uma kuqhathaniswa isikhathi eside. Eminyakeni yamuva, ngenxa yokuguquguquka kwezinye izitshalo ze-n-butanol esifundazweni saseShandong nezinye izici, uhlu lwezitshalo kule ndawo luyaqhubeka luphansi futhi intengo iphezulu, okwenza inzuzo yokukhiqiza i-butyl acetate esifundazweni saseShandong. ngokuvamile iphansi, futhi ukuzimisela kwabakhiqizi abakhulu ukuqhubeka nokwenza inzuzo nokuthunyelwa kwemikhumbi kuphansi futhi intengo iphakeme kakhulu.

Ngenxa yomehluko enzuzweni, ukukhishwa kweShandong neJiangsu nakho kuhlukile. NgoNovemba, inani eliphelele le-butyl acetate lalingamathani angu-53300, okuwukukhuphuka ngo-8.6% ngenyanga kanye no-16.1% unyaka nonyaka.

ENyakatho neChina, umphumela wehliswa kakhulu ngenxa yezinkinga zezindleko. Isamba esiphuma nyanga zonke sasicishe sibe ngamathani angama-8500, sehle ngo-34% ngenyanga,

Umphumela eMpumalanga China wawucishe ube ngamathani angama-27000, ukhuphuke ngo-58% ngenyanga.

Ngokusekelwe esikhaleni esisobala ngasohlangothini lwempahla, isasasa lamafekthri amabili okuthumela impahla nawo akuhambisani.

Esikhathini sakamuva, ukuguqulwa okuphelele kwe-n-butanol akubalulekile ngaphansi kwesizinda sokusungula okuphansi, intengo ye-acetic acid ingase iqhubeke nokwehla, ukucindezela kwezindleko ze-butyl acetate kungase kube buthaka kancane kancane, futhi ukunikezwa kwe-Shandong kulindeleke ukuthi ukwanda. I-Jiangsu kulindeleke ukuthi inciphise ukunikezwa kwayo ngenxa yomthwalo omkhulu wokwakha ekuqaleni kanye nokugaya okukhulu esikhathini esizayo esiseduze. Ngaphansi kwesizinda esingenhla, kulindeleke ukuthi umehluko wentengo phakathi kwalezi zindawo ezimbili uzobuyela kancane kancane ezingeni elivamile.
