I-acryloniThiTle yenziwa ngokusebenzisa i-propylene ne-ammonia njengezinto zokwakha, ngokusebenzisa i-oxidation reaction kanye nenqubo yokucwilisa. Kuyinto ehlanganisiwe ye-organic ngefomula yamakhemikhali C3H3N, uketshezi olungenamibala ngephunga elicasulayo, elivuthayo, umphunga walo nomoya angadala i-flome evulekile, futhi kusalokhu kudalulwe ngo-oxidizer, futhi kuphendula ngobudlova ngama-oxidizers, ama-acid aqinile, ama-anine aqinile.

Isetshenziswa ikakhulukazi njengento eluhlaza ye-acrylic ne-abs / san resin, futhi isetshenziswa kabanzi ekukhiqizweni kwe-acrylamide, unamathisele kanye ne-adiponitritri, irabha yokwenziwa, i-latex, njll.

Izicelo zemakethe ye-acrylonitrite

I-acryloniThiTile iyinto ebalulekile eluhlaza ebonakalayo yezinto zokwenziwa ezinkulu zokwenziwa (amapulasitiki, irabha yokwenziwa kanye nokusetshenziswa kwe-acryntuam), kanye nokusetshenziswa kwe-acryramite), okuyinto engaphezulu kuka-80% yokusetshenziswa okuphelele kwe-acrylonitritria. Eminyakeni yamuva nje, iChina selibe lilinye lamazwe akhula ngokushesha kakhulu emakethe ye-acrylonitrile yomhlaba ngokuthuthukiswa kwezinto zasekhaya nezimboni zemoto. Imikhiqizo eyehlayo isetshenziswa kabanzi emikhakheni ehlukahlukene yomnotho wezwe, njengemishini yasekhaya, izembatho, izimoto, kanye nemithi.

I-acryloniThile yenziwa kusuka ku-propelene nase-ammonia ngokusabela kwe-oxidation kanye nenqubo yokuhlanza, futhi isetshenziswa kabanzi ku-resin, ukukhiqizwa kwezimboni ze-acrylic, kanye ne-carbon fiber, kanye ne-carbon fiber izindawo ezinesidingo esisheshayo ngokuzayo.

I-Carbon fiber, njengomunye wokusetshenziswa okubalulekile kwehla kwe-acrylonitritrile, yinto entsha njengamanje egxile ocwaningweni nasekuthuthukisweni nasekukhiqizweni eChina. I-Carbon fiber isiphenduke ilungu elibalulekile lezinto zokwakha ezingasindi, futhi kancane kancane zithathe izinto zensimbi ezedlule, futhi ziye zaba yinto yohlelo lokusebenza olusemqoka ezinkambeni zomphakathi kanye nezempi.

Njengoba umnotho waseChina uyaqhubeka ukuthuthuka ngejubane elisheshayo, isidingo se-carbon fiber nezinto zaso ezinhlanganisela ziyaqhubeka nokuhlinzwa. Ngokusho kwezibalo ezifanele, isidingo se-carbon fiber eChina sifinyelela amathani angama-48,800 ngonyaka ka-2020, ukukhuphuka kwama-29% ngaphezulu konyaka we-2019.

Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, imakethe ye-acrylonitrile ikhombisa izitayela ezinkulu zentuthuko.
Okokuqala, indlela yokukhiqizwa kwe-acrylonitrile esebenzisa iPropane njengoba kukhuthazeka kancane kancane.
Okwesibili, ucwaningo lwama-catalysts amasha luyaqhubeka nokuba yisihloko sokucwaninga izazi ezifuywayo nakwamanye amazwe.
Okwesithathu, isilinganiso esikhulu sesitshalo.
Okwesine, ukonga amandla nokuncishiswa kokuphuma, ukusebenziseka kwenqubo kuya ngokuya kubaluleke kakhulu.
Ukwelashwa kwamanzi okuhlanu, owayengumdaka sekuphenduke okuqukethwe okubalulekile kocwaningo.

Ukukhiqizwa kwamandla acrylonitrile amakhulu

Izikhungo zokukhiqiza zaseChina acrylonitriterinte zasekhaya zigxile kakhulu kumabhizinisi aphethwe yiChina Petroleum & Chemical Corporation (Sinopec) kanye neChina National Petroleum Corporation (CNPC). Phakathi kwazo, inani eliphelele lokukhiqiza le-sinopec (kufaka phakathi ukungena okuhlanganyelwe) lingamathani angama-860,000, accounting ama-34.8% wamandla okukhiqiza aphelele; Umthamo wokukhiqiza we-petrochina amathani angama-700,000, afaka ama-28.3% wamandla okukhiqiza aphelele; Umthamo wokukhiqiza wamabhizinisi wangasese uJiangsu Searchemical, uShandong Haijiang Chemical Cons wamathani angama-520,000, amathani angama-130,000 namathani angama-260,000 ahlanganisiwe ngokulandelana okungu-36.8%.

Kusukela engxenyeni yesibili ka-2021, isigaba sesibili se-zpmc enamathani angama-260,000 / unyaka wesibili we-khrueli namathani we-acryonitrile / ngonyaka omusha we-acrylonitrile / ngonyaka we-acrylonitrile afakwe ku-910,000 amathani Umthamo we-acryloniturile ufinyelele amathani / ngonyaka wezigidi ezingama-3.419.

Ukwanda komthamo we-acrylonitile akuyeki lapha. Kuyaqondakala ukuthi ngo-2022, isitshalo esisha esingu-260,000 amathani / unyaka acrylonitrile sizofakwa ekusebenzeni e-East China, isitshalo seminyaka engu-130,000 / yonyaka eGuangdong kanye nesitshalo sonyaka ka-200,000 eHainan. Umthamo omusha wokukhiqiza wasekhaya awusekho okukhawulelwe e-East China, kepha uzosatshalaliswa ezifundeni eziningana eChina, ikakhulukazi isitshalo esisha eHainan sizofakwa ekusetshenzisweni ukuze imikhiqizo isondelene neSouth China naseSoutheast Asia izimakethe, futhi kulula kakhulu ukuthumela ngaphandle kolwandle.

Umthamo okhule kakhulu wokukhiqiza uletha ukukhuphuka ekukhiqizweni. Izibalo zeJinlia zibonisa ukuthi ukukhiqizwa kwe-acrylonitritrile yaseChina kwaqhubeka nokusetha okuphezulu ngo-2021. Ekupheleni kukaDisemba 2021, ukukhiqizwa okuphelele konyaka, ngenkathi ukusetshenziswa konyaka kube yiminyaka engu-2617.

Ukuqondiswa kwentuthuko yesikhathi esizayo kwe-acrylonitrile

Ngonyaka ka-2021 edlule, ukuthunyelwa kwamanye amazwe acrylonitrite kudlule okokuqala ngqa. Ukungenisa okuphelele kwemikhiqizo ye-acrylonitrile ngonyaka owedlule kwakungamathani angama-203,800, ezansi 33.55% kusukela ngonyaka owedlule, ngenkathi ukuthunyelwa kufinyelele kumathani angama-210,600, kwanda ngo-188.69% kusukela ngonyaka owedlule.

Lokhu akuhlukaniswa kusuka ekukhishweni okuhlangene kwamandla okukhiqiza amasha eChina kanye nemboni kusesimweni sokuguqulwa kusuka ekulinganiseni okuphezulu kokungaphezulu. Ngaphezu kwalokho, amayunithi amaningi ase-Europe kanye neMelika amise endaweni yokuqala neyesibili, okuholele ekuhlinzekeni okungazelelwe, ngenkathi amanani entengo e-Asia abephansi kunamanani e-Acryonitrile ahleliwe ukunwebeka, okubandakanya isifundazwe saseTaiwan saseChina, eduzane naseKorea, India naseTurkey.

Ukwanda kwevolumu yokuthumela ngaphandle kwahambisana nomkhuba ophakeme ngenani lamazwe athumela ngaphandle. Phambilini, imikhiqizo ye-ACRYLONITRILE Export Procers yathunyelwa ikakhulukazi eSouth Korea naseNdiya. 2021, ngokuncipha kokuhlinzekwa kwaphesheya kwezilwandle, ivolumu e-acrylonitriteriles export yanda futhi yathunyelwa emakethe yaseYurophu, okubandakanya amazwe ayisikhombisa nezifunda ezifana neTurkey neBelgium.

Kubikezelwa ukuthi izinga lokukhula le-acrylonitrile yokukhiqiza amandla e-China eminyakeni ezayo likhulu kunesibalo sokukhula esisezingeni eliphansi, kanti ukuthunyelwa kwamanye amazwe kuzoqhubeka nokukhulisa, kulindeleke ukuthi kuthunyelwe amathani aphezulu, ngakho-ke kuzoqhubeka nokucindezela ekusebenzeni kwemakethe yaseChina.

UChemWin uthengisa ikhwalithi ephezulu, ephansi ebiza i-acrylonitrite feedstock esitokweni emhlabeni jikelele
