1,Ukwenyuswa kwamanani entengo ephelele ekhefini lemboni ye-phenone ye-phenone

Ngesonto eledlule, ukudluliswa kwezindleko ze-phenolic yetone imboni chain wawubushelelezi, futhi amanani amaningi omkhiqizo akhombisa ukuthambekela okuphezulu. Phakathi kwazo, ukwanda kwe-acetone kwakubaluleke kakhulu, kufinyelela ngo-2.79%. Lokhu kungenxa yokwehla kokuhlinzekwa kwemakethe ye-propenene kanye nokusekelwa kwezindleko eziqinile, okuholela ekwandeni kwezingxoxo zemakethe. Umthwalo wokusebenza wefektri yasekhaya acetone ulinganiselwe, futhi imikhiqizo ibeka phambili ngokuhlinzekwa okuphansi. Ukujikeleza kwendawo eqinile emakethe kuqhuba amanani.

2,Ukuguquguquka okuguquguqukayo kanye nokushintshana kwentengo emakethe ye-MMA

Ngokungafani neminye imikhiqizo esembonini, inani elijwayelekile le-MMA liyaqhubeka nokwehla ngeledlule, kepha umkhondo wentengo yansuku zonke wakhombisa ukwehla kokuqala okulandelwa ukwanda. Lokhu kungenxa yokugcinwa okungahleliwe kwamanye amadivaysi, okuholela ekwehleni kwesilinganiso sokusetshenziswa komthwalo we-MMA kanye nokuhlinzekwa kwezindawo eziqinile emakethe. Ngokungeza ukwesekwa kwezindleko, amanani emakethe akhuphukile. Le nto ibonisa ukuthi yize amanani entengo e-MMA athintwa ukushoda kokuphakelayo esikhathini esifushane, izici zezindleko zisasekele amanani emakethe.

3, ukuhlaziywa kokuhambisa izindleko kwe-Benzene ye-Benzene emsulwa iBisphenol

Ku-Benzene Phezene Bhenol Bisphenol I-Chain, Ukudluliselwa Kwezindleko

Umphumela usanele. Yize i-benzene ebumsulwa ibhekana nokulindelwe kokuncishiswa kokukhiqizwa kwe-saudi Arabia, ukusungula okukhawulelwe kanye nokufika okulandelayo echwebeni elikhulu e-East China kuholele ekuhlinzekeni kwamakethe kanye nezintengo eziqhutshwa. Intengo yokungenisa kwentengo ye-phenol kanye ne-upstream pure benzile ishaye entsha ephansi kulo nyaka, inomphumela wokukhulisa izindleko. Ukujikeleza kwendawo enganele ye-bisphenol a, kuhlanganiswe nengcindezi yezindleko, ukusekelwa kwamafomu amanani kusuka kuzo zombili izindleko nezinhlangothi zokuhambisa. Kodwa-ke, ukwanda kwentengo okuphansi kungaphansi kwezinga lokukhula kwezinto zokwakha, okukhombisa ukuthi lokho kudluliselwa kwezindleko ku-Downstream kubhekene nezithiyo ezithile.

3,Inzuzo ephelele ye-phenolic yetone imboni chain

Yize intengo ephelele ye-phenolic katone embonini embonini yanda, isimo senzuzo jikelele asisenathemba. Ukulahleka kwethiyori kwe-Phenol Ketone C COURDOR kuyinto 925 Yuan / Ton, kepha ubukhulu bokulahlekelwa sekwehlile kuqhathaniswa nesonto eledlule. Lokhu kungenxa yokwanda kwamanani entengo ye-phenol ne-acetone, kanye nokwanda okuphelele okuphelele kuqhathaniswa nezinto ezivuthiwe ze-benzeze emsulwa ne-propylene, okuholele emugqeni wenzuzo onwetshiwe. Kodwa-ke, imikhiqizo eyehlayo efana ne-bisphenol a yenziwe kabi ngokuya ngenzuzo, ngokulahleka kwethiyori ka-964 yuan / ton, ukwanda kobukhulu bokulahlekelwa kuqhathaniswa nesonto eledlule. Ngakho-ke, kuyadingeka ukunaka ukuthi kunezinhlelo zokunciphisa ukukhiqizwa futhi zivale phansi i-phenol ketone ne-bisphenol amayunithi esigabeni esizayo.

4,Ukuqhathaniswa kwenzuzo phakathi kwendlela ye-acetone hydrogenation ye-acetone ne-MMA

Emikhiqizweni eyehlayo ye-acetone, inzuzo ye-acetone hydrogenation shopropanol iyehlile kakhulu, inzuzo esezingeni eliphakeme kakhulu ye--260 yuan / ton ngeledlule ngesonto eledlule, inyanga ngenyanga yehla ngo-50,00%. Lokhu kungenxa yentengo ephakeme kakhulu ye-Acetone eluhlaza kanye nokwanda okuncane kwamanani entengo ephansi. Ngokuphambene nalokho, yize intengo ne-margin yenzuzo ye-MMA yehle, isalokhu igcina inzuzo eqinile. Ngesonto eledlule, isilinganiso semboni esembonini yezempi sasiyinzuzo enkulu ye-theoretical yayingu-4603.11 yuan / ton, okuyinto ephakeme kunazo zonke enenzuzo ekhasini lezinhlobo ze-phenolic yetone.
