2. Ukuhlaziywa kwendlela yemakethe ye-ethyl acetate
Kule nyanga, i-ethyl acetate yasekhaya yayisesimweni esibuthakathaka, futhi izimboni ezinkulu eShandong zaqala ukusebenza, futhi ukunikezwa kwanda uma kuqhathaniswa nalokho.I-ethyl acetate yacindezelwa ukunikezwa nokufunwa okuxekethile, ikakhulukazi ezinsukwini eziyishumi zokuqala, engazange ibone izinzuzo zezindleko ezikhuphukayo ze-acetic acid.Ngokwezibalo zeBusiness News Agency, ukwehla kwale nyanga kube ngu-0.24%.Ngasekupheleni kwenyanga, intengo yemakethe ye-ethyl acetate yayingu-6750-6900 yuan/ton.
Ukucacisa, isimo sokuhweba semakethe ye-ethyl acetate kule nyanga sibonakala sibanda, futhi ukuthengwa komfula ongezansi kuncane, futhi uhla lokuhweba lwe-ethyl acetate lungaphakathi kwebanga lama-yuan angu-50.Maphakathi nenyanga, nakuba amafekthri amakhulu eshintshile, ububanzi bokuguquguquka bulinganiselwe, futhi iningi lazo lilawulwa ngaphakathi kwama-yuan angu-100.Izingcaphuno zabakhiqizi abaningi abakhulu zizinzile, futhi izintengo zabanye abakhiqizi e-Jiangsu zehliswe kancane maphakathi nenyanga ngenxa yomthelela wengcindezi yokusungula.Abakhiqizi abakhulu be-Shandong bafuna ukuthunyelwa.Ukubhida kusabonisa ukuzethemba okunganele.Nakuba kunesivumelwano se-premium, intengo ayikadluli izinga lenyanga edlule.Intengo yezinto ezingavuthiwe ne-acetic acid yehle phakathi nezigaba zakamuva zemakethe, futhi imakethe ingase ibhekane nezindleko ezingezinhle.
3. Ukuhlaziywa kwethrendi yemakethe ye-butyl acetate
Kule nyanga, i-butyl acetate yasekhaya iphinde yagcwala ngenxa yokutholakala okuqinile.Ngokokuqapha kweBusiness News Agency, i-butyl acetate ikhuphuke ngo-1.36% nyanga zonke.Ekupheleni kwenyanga, ububanzi bentengo ye-butyl ester yasekhaya bekungu-7400-7600 yuan/ton.
Ngokukhethekile, ukusebenza kwe-acetic acid eluhlaza kwakubuthakathaka, futhi i-n-butanol yehle kakhulu, ngokwehla ngo-12% ngoFebhuwari, okwakungekuhle emakethe ye-butyl ester.Isizathu esiyinhloko esenza intengo ye-butyl ester ingalandeli ukwehla ukuthi ohlangothini lokuhlinzeka, izinga lokusebenza kwamabhizinisi lahlala liphansi, lisuka ku-40% ngoJanuwari laya ku-35%.Ukunikezwa kwahlala kuqinile.Umuzwa wokulinda bese ubona umfula uphansi uma kuqhathaniswa, imakethe ayinasenzo, futhi ukuthengiselana kwama-oda amaningi kuyivelakancane, futhi inkambiso ezinsukwini eziyishumi ezedlule imile.Amanye amabhizinisi aphoqeleka ukuthi alungise ngaphansi kwesimo sezindleko eziphezulu, futhi ukutholakala kwemakethe kanye nesidingo kwakungaqhubeki.
4. Amathemba esikhathi esizayo ochungechunge lwemboni ye-acetic acid

Esikhathini esifushane, imakethe ixubene nesikhathi eside nesifushane, kuyilapho izindleko zimbi, isidingo singase sithuthuke.Ngakolunye uhlangothi, kusenengcindezi ephansi ezindlekweni ezikhuphuka nomfula, okuzoletha izindaba ezimbi ochungechungeni lwemboni ye-acetic acid engezansi.Kodwa-ke, izinga lokusebenza lakho kokubili i-acetic acid ephezulu kanye namabhizinisi e-ethyl ephansi kanye ne-butyl ester ngokuvamile liphansi.I-inventory yomphakathi nayo ngokuvamile iphansi.Ngokuthuthuka okuqhubekayo kwesidingo setheminali esigabeni sakamuva, intengo ye-ethyl ester ezansi nomfula, i-butyl ester neminye imikhiqizo kungenzeka inyuke kancane.
