1,Ukukhuphuka kwentengo kukonke kuchungechunge lwemboni ye-phenolic ketone

Ngesonto eledlule, ukudluliswa kwezindleko zochungechunge lwemboni ye-phenolic ketone bekubushelelezi, futhi amanani entengo amaningi omkhiqizo akhombisa umkhuba okhuphukayo. Phakathi kwabo, ukwanda kwe-acetone kwakubaluleke kakhulu, kwafinyelela ku-2.79%. Lokhu kungenxa yokuncipha kokuhlinzekwa kwemakethe ye-propylene kanye nokusekelwa okuqinile kwezindleko, okuholela ekwandeni kwezingxoxo zemakethe. Umthwalo osebenzayo wamafekthri e-acetone asekhaya unomkhawulo, futhi imikhiqizo ibekwa phambili ekuhlinzekweni komfula. Ukusatshalaliswa kwezindawo eziqinile emakethe kuqhubeza nokwenyusa amanani.

2,Ukunikezwa okuqinile nokuguquguquka kwentengo emakethe ye-MMA

Ngokungafani neminye imikhiqizo echungechungeni lwemboni, intengo ejwayelekile ye-MMA iqhubekile nokwehla ngesonto eledlule, kodwa inkambiso yamanani yansuku zonke ibonise ukwehla kokuqala okulandelwa ukwanda. Lokhu kungenxa yokunakekelwa okungahleliwe kwamanye amadivaysi, okuholela ekwehleni kwezinga lokulayisha ukusebenza kwe-MMA kanye nokutholakala okuqinile kwezimpahla ezikhona emakethe. Ngokungeza ukusekelwa kwezindleko, amanani emakethe akhuphukile. Lesi simo sibonisa ukuthi nakuba izintengo ze-MMA zithintwa ukushoda kwempahla esikhathini esifushane, izici zezindleko zisasekela amanani emakethe.

3, Ukuhlaziywa Kokudluliselwa Kwezindleko Kwe-Pure Benzene Phenol Bisphenol A Chain

Ochungechungeni lwe-benzene phenol bisphenol A, ukudluliswa kwezindleko

umphumela usemuhle. Nakuba i-benzene emsulwa ibhekene nokulindelwe okungenathemba kokukhuphuka kokukhiqizwa e-Saudi Arabia, inani lempahla elilinganiselwe kanye nokufika okwalandela ethekwini elikhulu e-East China kuholele ekutholakaleni kwezimakethe okuqinile futhi kwakhuphula amanani. Ukuguqulwa kwentengo ye-phenol kanye ne-upstream pure benzene yehle kakhulu kulo nyaka, okunomphumela oqinile wokukhulisa izindleko. Ukusatshalaliswa kwendawo okunganele kwe-bisphenol A, okuhambisana nokucindezela kwezindleko, kwakha usekelo lwamanani avela kuzo zombili izinhlangothi zezindleko nezokuhlinzeka. Kodwa-ke, ukukhuphuka kwentengo ephansi komfula kungaphansi kwezinga lokukhula kwezinto zokusetshenziswa, okubonisa ukuthi ukudluliswa kwezindleko ukuya ezansi nomfula kubhekene nezithiyo ezithile.

3,Inzuzo isiyonke ye-phenolic ketone industry chain

Nakuba intengo iyonke ye-phenolic ketone industry chain iye yanda, isimo senzuzo sisonke asikabi nethemba. Ukulahlekelwa kwethiyori kokukhiqizwa kwe-phenol ketone co yi-925 yuan/ton, kodwa ubukhulu bokulahlekelwa behlile uma kuqhathaniswa nesonto eledlule. Lokhu kungenxa yokwenyuka kwamanani e-phenol ne-acetone, kanye nokwenyuka okukhulu uma kuqhathaniswa nezinto ezingavuthiwe ze-benzene ne-propylene, okuholela emalini yenzuzo eyandisiwe. Kodwa-ke, imikhiqizo engezansi efana ne-bisphenol A ayisebenzi kahle ngokwenzuzo, ngokulahleka kwethiyori okungu-964 yuan/ton, okuwukukhuphuka kobukhulu bokulahlekelwa uma kuqhathaniswa nesonto eledlule. Ngakho-ke, kuyadingeka ukunaka ukuthi kukhona yini izinhlelo zokunciphisa ukukhiqizwa nokuvala amayunithi e-phenol ketone kanye ne-bisphenol A esigabeni esilandelayo.

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

Emikhiqizweni ye-acetone ezansi nomfula, inzuzo ye-acetone hydrogenation isopropanol yehle kakhulu, ngesilinganiso senzuzo yengqikithi engu-260 yuan/ton ngesonto eledlule, inyanga ngenyanga yehle ngo-50.00%. Lokhu kungenxa yentengo ephezulu uma kuqhathaniswa ye-acetone eluhlaza kanye nokwenyuka okuncane uma kuqhathaniswa nezintengo ze-isopropanol ezansi nomfula. Ngokuphambene, nakuba inani lentengo nenzuzo ye-MMA yehlile, isalondoloza inzuzo eqinile. Ngesonto eledlule, isilinganiso senzuzo yetiyori yesilinganiso somkhakha sasingu-4603.11 yuan/ton, okuyinto enenzuzo ephezulu kakhulu ochungechungeni lwemboni ye-phenolic ketone.
