Imakethe ye-isopropanol yawa kuleli sonto. NgoLwesine olwedlule, intengo emaphakathi ye-isopropanol e-China yayingu-7140 yuan/ton, intengo emaphakathi yangoLwesine yayingu-6890 yuan/ton, kanti intengo evamile yamasonto onke yayingu-3.5%.

Kuleli sonto, imakethe ye-isopropanol yasekhaya ithole ukwehla, okudonse ukunakwa kwemboni. Ukukhanya kwemakethe kuye kwakhula nakakhulu, futhi ukugxila kwemakethe yasekhaya ye-isopropanol kushintshe kakhulu phansi. Lokhu mkhuba okwehlayo kuthintwa kakhulu ukwehla kwezintengo ze-acetone ne-acrylic acid, okwenza buthaka ukusekela kwezindleko ze-isopropanol. Ngaleso sikhathi, umdlandla wokuthenga izinto ezingaphansi komfula uphansi uma kuqhathaniswa, ikakhulukazi ukwamukela ama-oda lapho kudingeka khona, okuholela emsebenzini ophansi wokuthenga wemakethe. Ama-opharetha ngokuvamile athatha isimo sengqondo sokulinda nokubona, ngesidingo esincishisiwe semibuzo kanye nokwehla kwesivinini sokuhambisa.
Ngokusho kwedatha yemakethe, kusukela manje, ikhotheshini ye-isopropanol esifundeni sase-Shandong cishe i-6600-6900 yuan/ton, kuyilapho ingcaphuno ye-isopropanol ezifundeni zase-Jiangsu ne-Zhejiang cishe i-6900-7400 yuan/ton. Lokhu kukhombisa ukuthi intengo yemakethe yehle ngezinga elithile, futhi ubudlelwano bokunikezela nokufunwa bubuthaka uma kuqhathaniswa.

Mayelana ne-acetone eluhlaza, imakethe ye-acetone nayo yehle kuleli sonto. Idatha ibonisa ukuthi intengo emaphakathi ye-acetone ngoLwesine olwedlule ibingu-6420 yuan/ton, kuyilapho intengo emaphakathi yangoLwesine ibingu-5987.5 yuan/ton, ukwehla ngo-6.74% uma kuqhathaniswa neviki eledlule. Izinyathelo zefekthri zokunciphisa amanani emakethe ngokusobala zibe nomthelela omubi emakethe. Nakuba izinga lokusebenza lezitshalo ze-phenolic ketone ezifuywayo lehlile, ingcindezi yokusungula yezimboni iphansi kakhulu. Kodwa-ke, ukuthengiselana kwemakethe kubuthakathaka futhi isidingo sokugcina asisebenzi, okuholela ekungeneni kwevolumu ye-oda langempela.

Imakethe ye-acrylic acid nayo ithintwa ukwehla, amanani akhombisa ukwehla. Ngokwezibalo, intengo emaphakathi ye-acrylic acid e-Shandong ngoLwesine olwedlule ibingu-6952.6 yuan/ton, kanti intengo emaphakathi yalo ngoLwesine ibingu-6450.75 yuan/ton, ukwehla ngo-7.22% uma kuqhathaniswa nesonto eledlule. Imakethe yesidingo esibuthakathaka iyisizathu esiyinhloko salokhu kwehla, ngokunyuka okukhulu kwempahla ekhuphuka nomfula. Ukuze kugqugquzelwe ukulethwa kwezimpahla, ifekthri kufanele yehlise amanani futhi ikhiphe ukukhishwa kwempahla. Kodwa-ke, ngenxa yokuthenga okucophelelayo kanye nomuzwa onamandla wokulinda nokubona izimakethe, ukukhula kwesidingo kunqunyelwe. Kulindeleke ukuthi isidingo esingaphansi komfula ngeke sithuthuke kakhulu esikhathini esifushane, futhi imakethe ye-acrylic acid izoqhubeka nokugcina umkhuba obuthakathaka.
Sekukonke, imakethe yamanje ye-isopropanol ngokuvamile ayinamandla, futhi ukwehla kwezintengo ze-acetone ne-acrylic acid kubangele ingcindezi enkulu emakethe ye-isopropanol. Ukwehla okukhulu kwezintengo ze-acetone kanye ne-acrylic acid kuholele ekusekelweni kwezimakethe okubuthakathaka, okuhambisana nesidingo esibuthakathaka somfula, okuholela ekuhwebeni kwemakethe okungekuhle. Abasebenzisi abashona phansi nabahwebi banomdlandla ophansi wokuthenga kanye nesimo sengqondo sokulinda bese ubona ngemakethe, okuholela ekungazethembini kwemakethe okwanele. Kulindeleke ukuthi imakethe ye-isopropanol iqhubeke nokuba buthakathaka esikhathini esifushane.
Kodwa-ke, ababukeli bezimboni bakholelwa ukuthi nakuba imakethe yamanje ye-isopropanol ibhekene nengcindezi ephansi, kunezici ezithile ezinhle. Okokuqala, ngokuthuthukiswa okuqhubekayo kwezidingo zemvelo kazwelonke, i-isopropanol, njenge-solvent enobungani bemvelo, isenamandla athile okukhula emikhakheni ethile. Okwesibili, ukubuyiswa kabusha kokukhiqizwa kwezimboni ngaphakathi nakwamanye amazwe, kanye nokuthuthukiswa kwezinkambu ezisafufusa ezifana nezingubo zokugqoka, uyinki, amapulasitiki nezinye izimboni, kulindeleke ukuthi kukhuphule imakethe ye-isopropanol. Ngaphezu kwalokho, abanye ohulumeni basekhaya bakhuthaza ngenkuthalo ukuthuthukiswa kwezimboni ezihlobene ne-isopropanol, bafaka amandla amasha emakethe ngokusekelwa kwenqubomgomo kanye nesiqondiso sokusungula.
Ngokombono wemakethe yamazwe ngamazwe, imakethe ye-isopropanol yomhlaba wonke nayo ibhekene nezinselelo namathuba athile. Ngakolunye uhlangothi, umthelela wezinto ezinjengokushintshashintsha kwamanani entengo kawoyela wamazwe ngamazwe, ubungozi bezwe, kanye nokungaqiniseki esimweni somnotho wangaphandle emakethe ye-isopropanol akunakunakwa. Ngakolunye uhlangothi, ukusayinwa kwezivumelwano zokuhwebelana zamazwe ngamazwe kanye nokukhuthazwa kokubambisana kwezomnotho kwesifunda kuye kwanikeza amathuba amasha kanye nendawo yokuthuthukiswa kwezimakethe zokuthunyelwa kwe-isopropanol.
Kulo mongo, amabhizinisi embonini ye-isopropanol adinga ukuphendula ngokuguquguqukayo ezinguqukweni zemakethe, aqinise ucwaningo lwezobuchwepheshe nentuthuko kanye nokusungulwa komkhiqizo, athuthukise ikhwalithi yomkhiqizo kanye nenani elingeziwe, futhi athole amaphuzu okukhula amasha. Ngesikhathi esifanayo, qinisa ucwaningo lwemakethe kanye nokuqoqwa kolwazi, ukuthambekela kwemakethe okubamba ngesikhathi, futhi ulungise ngokuguquguqukayo amasu okukhiqiza nawokuthengisa ukuze kuthuthukiswe ukuncintisana kwemakethe.
