1.Ukuhlaziywa komfulai-acetic acidumkhuba emakethe

Isilinganiso sentengo ye-acetic acid ekuqaleni kwenyanga yayingu-3235.00 yuan/ton, futhi intengo ekupheleni kwenyanga yayingu-3230.00 yuan/ton, ukukhuphuka ngo-1.62%, futhi intengo yayingaphansi ngo-63.91% kunonyaka odlule.

NgoSepthemba, imakethe ye-acetic acid yayibuswa uhla olubanzi lwe-oscillation, nezintengo zehla ngaphambi kokukhuphuka. Engxenyeni yokuqala yonyaka, imakethe ye-acetic acid yayihlanganiswe, nokutholakala okwanele, isidingo esilinganiselwe esiphansi somfula, ukunikezwa kwemakethe okubuthakathaka kanye nesidingo, amanani e-acetic acid aguquguquka; engxenyeni yesibili yonyaka, imakethe ye-acetic acid yayibuthakathaka futhi yehla, ikakhulukazi ngenxa yokuthi amabhizinisi okugcina i-acetic acid aphinde aqala ukusebenza okuvamile, ukunikezwa kwemakethe kwakwanele, ukuthengwa komfula kwaqhubeka nokuba buthaka, ukunikezwa kwakunamandla futhi kubuthakathaka, amanani e-acetic acid aqhubeka nokwehla; ekupheleni kwenyanga, iholidi Losuku Lukazwelonke lase lisondela, isidingo sokuthola isitokwe esingezansi komfula sakhula, futhi amabhizinisi ayenenhloso eqinile yokunyusa amanani. Ekupheleni kwenyanga, ukunikezwa kwenyukile, kulandelwa ukwenyuka kwentengo ye-methanol ekhuphuka nomfula, ukusekelwa kwempahla eluhlaza kuhle, ekupheleni kwenyanga amanani e-acetic acid akhuphuke cishe ekuqaleni kwenyanga.

2. Ukuhlaziywa kwemakethe ye-ethyl acetate

Ngo-September, i-ethyl acetate yasekhaya isebuthakathaka, imakethe isaqhubeka nenqubo yokuphuma. Ngokwezibalo zeBusiness News Service, ukwehla kule nyanga kwaba ngu-0.43%, futhi ngasekupheleni kwenyanga, intengo yemakethe ye-ethyl acetate yayingu-6700-7000 yuan/ton.

Kule nyanga, uhlangothi lwezindleko lwe-ethyl acetate alulungile kakhulu, i-acetic acid iningi lenyanga lihlehla libheke phansi, isonto lokugcina likaSepthemba liphinde lavuka, okuholela esikhathini esifushane se-ethyl acetate phezulu, ukuphela kwenyanga akukwazi ukusimama, amanani namanje awakabuyeli ekuqaleni kwezinga. Kube noshintsho oluncane ohlangothini lokuhlinzeka, izitshalo eziningi eMpumalanga yeShayina bezisebenza ngokujwayelekile, futhi amandla okuthunyelwa kwezinkampani awazange alethe isizini ephezulu ye-“Golden Nine”, futhi uhlu lwamagama lwahlala luphezulu. Ushintsho oluphelele lwentengo yokubhida yezitshalo ezinkulu eShandong alubalulekile. Ubuthakathaka bemakethe ephansi komfula kunzima ukuthuthukisa, futhi ukuthengwa kwempahla kusalokhu kuzinzile nje isidingo.

I-3.butyl acetate ukuhlaziywa kwemakethe yemakethe

I-Domestic butyl acetate iqhubekile nokucwiliswa ngoSepthemba, futhi imakethe yayisebuthakathaka. Ngokusho kweBusiness Newswire, ukwehla kwanyanga zonke kwe-butyl acetate kube ngu-2.37%. Ekupheleni kwenyanga, ububanzi bentengo ye-butyl acetate yasekhaya bekungu-7,200-7,500 yuan/ton.

Ngakolunye uhlangothi, uhlangothi lwezindleko luhlukanisiwe, nakuba i-acetic acid iphinde yagcwala ekupheleni kwenyanga, kodwa kusenzima ukukhipha i-acetate ye-butyl ephuma esigayegayeni, omunye umkhiqizo okhuphuka nomfula u-n-butanol ushaqeke phansi, wehle ngo-2.91% ngenyanga. Sekukonke, uhlangothi lwezindleko lusabuswa uhlangothi olufushane. Intengo efiphele yesikhathi eside ye-butyl acetate ikakhulukazi isuka ekucindezelweni kokuhlinzekwa nokufunwa: isimo sokuqalisa somshini, izinga lokuqalisa amabhizinisi e-butyl lishintsha kancane, izinga lokuqalisa kwezitshalo ezinkulu ukuze kugcinwe izinga eliphezulu neliphansi ngama-40%, kodwa ingcindezi yokusungula yezitshalo ezinkulu iyabonakala, ngaphansi kwethonya lesidingo esibuthakathaka, ukuthengiselana kwemakethe akukuhle. Itheminali igcina isidingo nje, futhi isimo sokuhweba jikelele silula.

4.Ukuhlaziywa kochungechunge lwemboni ye-acetic acid

Kusukela eshadini lokuqhathanisa lokukhuphuka nokuwa kweketango lemboni ye-acetic, singabona ukuthi uchungechunge lwemboni lubonisa ukuthambekela kokubandayo phezulu nokushisa phansi, ne-methanol (19.17%) ekugcineni komthombo ikhuphuka kakhulu, ibeka ingcindezi enkulu ku-acetic acid kanye nomfula ophansi. Ikakhulukazi, i-ethyl ester engezansi ne-butyl ester azikakhululeki emakethe engemihle. Inzuzo ephambene yamabhizinisi phakathi nenyanga iphinde yagcina izinga lokuqalisa lisezingeni eliphansi, ngokuqedwa okungekuhle kakhulukazi.

Esikhathini esifushane, uchungechunge lwezimboni ze-acetic acid luzogcina ukuqedwa okubuthakathaka, abakhiqizi be-acetic acid bangase baqongelele amasheya phakathi nenkathi yeholide, kodwa amasheya aphansi e-ethyl acetate, i-butyl acetate ne-PTA ayaqhubeka nokudliwa phakathi nomkhosi, futhi ukugcwaliswa kwemakethe ngemva komkhosi kuzoletha izinzuzo ku-acetic acid. Kodwa-ke, uma kucatshangelwa ukuthuthukiswa okuncane kwesidingo sokugcina. Izintengo ze-Ethyl ester ne-butyl ester zingahlala zibuthakathaka.
