Acrylonitrile amapangidwa pogwiritsa ntchito propylene ndi ammonia monga zopangira, kudzera mukuchita kwa okosijeni ndi njira yoyenga.Ndi organic pawiri ndi mankhwala chilinganizo C3H3N, madzi opanda mtundu ndi fungo lopweteka, kuyaka, nthunzi yake ndi mpweya akhoza kupanga kuphulika osakaniza, ndipo n'zosavuta kuyambitsa kuyaka pamene lotseguka lawi ndi kutentha kwambiri, ndipo zimatulutsa mpweya wapoizoni. , ndipo amachitira mwachiwawa ndi okosijeni, asidi amphamvu, maziko amphamvu, amines ndi bromine.

Amagwiritsidwa ntchito ngati zopangira za acrylic ndi ABS / SAN resin, komanso amagwiritsidwa ntchito kwambiri popanga acrylamide, phala ndi adiponitrile, labala kupanga, Latex, etc.

Acrylonitrile Market Applications

Acrylonitrile ndi zofunika zopangira zinthu zitatu zikuluzikulu kupanga (pulasitiki, kupanga mphira ndi kupanga ulusi), ndi kumwa kunsi kwa madzi acrylonitrile ku China anaikira mu ABS, akiliriki ndi acrylamide, amene chifukwa oposa 80% ya mowa okwana acrylonitrile.M'zaka zaposachedwa, China yakhala imodzi mwamayiko omwe akukula mwachangu pamsika wapadziko lonse wa acrylonitrile ndi chitukuko cha mafakitale apanyumba ndi magalimoto.Zogulitsa zam'munsi zimagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana azachuma chadziko, monga zida zapakhomo, zovala, magalimoto, ndi mankhwala.

Acrylonitrile amapangidwa kuchokera ku propylene ndi ammonia ndi ma oxidation reaction ndi kuyenga, ndipo amagwiritsidwa ntchito kwambiri mu utomoni, kupanga ma acrylic mu mafakitale, ndi kaboni fiber ndi madera ogwiritsira ntchito omwe akukula mwachangu mtsogolo.

Mpweya wa carbon, monga imodzi mwazinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito kumunsi kwa acrylonitrile, ndi nkhani yatsopano yomwe ikuyang'ana pa kafukufuku ndi chitukuko ndi kupanga ku China.Mpweya wa kaboni wakhala membala wofunikira pazida zopepuka, ndipo pang'onopang'ono amatenga zida zachitsulo zam'mbuyo, ndipo wakhala chinthu chofunikira kwambiri pantchito zankhondo ndi zankhondo.

Pomwe chuma cha China chikupitilira kukula mwachangu, kufunikira kwa kaboni fiber ndi zida zake zophatikizika kukukulirakulira.Malinga ndi ziwerengero zoyenera, kufunikira kwa carbon fiber ku China kumafika matani 48,800 mu 2020, kuwonjezeka kwa 29% kuposa 2019.

Ndi chitukuko chosalekeza cha sayansi ndi zamakono, msika wa acrylonitrile umasonyeza zochitika zazikulu zachitukuko.
Choyamba, njira yopangira acrylonitrile pogwiritsa ntchito propane monga feedstock ikulimbikitsidwa pang'onopang'ono.
Chachiwiri, kufufuza kwa zoyambitsa zatsopano kukupitirizabe kukhala mutu wofufuza kwa akatswiri apakhomo ndi akunja.
Chachitatu, kukula kwakukulu kwa mbewu.
Chachinayi, kupulumutsa mphamvu ndi kuchepetsa umuna, kukhathamiritsa kwa ndondomeko ndikofunika kwambiri.
Chachisanu, chithandizo chamadzi onyansa chakhala chofunikira kwambiri pa kafukufuku.

Acrylonitrile Major Capacity Production

Malo opangira ma acrylonitrile aku China amakhala makamaka m'mabizinesi a China Petroleum & Chemical Corporation (Sinopec) ndi China National Petroleum Corporation (CNPC).Pakati pawo, mphamvu zonse zopanga za Sinopec (kuphatikizapo matani a 860,000), zomwe zimawerengera 34,8% ya mphamvu zonse zopangira;mphamvu yopanga PetroChina ndi matani 700,000, owerengera 28.3% ya mphamvu yonse yopanga;mphamvu yopanga mabizinezi payekha Jiangsu Searborn Petrochemical, Shandong Haijiang Chemical Co. Ltd. ndi mphamvu acrylonitrile kupanga matani 520,000, matani 130,000 ndi matani 260,000 motero, mlandu ophatikizana okwana kupanga mphamvu pafupifupi 36.8%.

Kuyambira theka lachiwiri la 2021, gawo lachiwiri la ZPMC ndi matani 260,000 / chaka, gawo lachiwiri la Kruel ndi matani 130,000 / chaka, gawo lachiwiri la Lihua Yi ndi matani 260,000 / chaka ndi gawo lachitatu la Srbang ndi matani 260,000 / Chaka cha acrylonitrile chakhala chikugwiritsidwa ntchito chimodzi pambuyo pa chimzake, ndipo mphamvu yatsopano yafika matani 910,000 / chaka, ndipo mphamvu zonse zapakhomo za acrylonitrile zafika matani 3.419 miliyoni / chaka.

Kukula kwa mphamvu ya acrylonitrile sikuyima apa.Zikumveka kuti mu 2022, chomera chatsopano cha matani 260,000 / chaka cha acrylonitrile chidzayamba kugwira ntchito ku East China, chomera cha matani 130,000 / chaka ku Guangdong ndi chomera cha matani 200,000 / chaka ku Hainan.Kuthekera kwatsopano kwapakhomo sikulinso ku East China, koma kugawidwa m'madera angapo ku China, makamaka chomera chatsopano ku Hainan chidzagwiritsidwa ntchito kuti zinthuzo zikhale pafupi ndi misika ya South China ndi Southeast Asia, ndipo ndi yabwino kwambiri kutumiza kunja ndi nyanja.

Kuwonjezeka kwakukulu kwa kupanga kumabweretsa kukwera kwa kupanga.Ziwerengero za Jinlian zikuwonetsa kuti kupanga kwa acrylonitrile ku China kudapitilirabe kupitilira mu 2021. Pofika kumapeto kwa Disembala 2021, kupanga okwana m'banja la acrylonitrile kudaposa matani 2.317 miliyoni, mpaka 19% pachaka, pomwe kumwa pachaka kunali pafupifupi matani 2.6 miliyoni. , ndi zizindikiro zoyamba za kupitirira malire mu malonda.

Chitukuko chamtsogolo cha acrylonitrile

M'chaka cha 2021 posachedwapa, malonda a acrylonitrile adadutsa kunja kwa nthawi yoyamba.Zomwe zimatumizidwa kuzinthu za acrylonitrile chaka chatha zinali matani 203,800, pansi pa 33.55% kuchokera chaka chatha, pamene kutumiza kunja kunafika matani 210,200, kuwonjezeka kwa 188.69% kuchokera chaka chatha.

Izi sizingasiyane ndi kutulutsidwa kwakukulu kwa mphamvu zatsopano zopangira ku China ndipo bizinesi ili pakusintha kuchoka pamlingo wokhazikika kupita ku zochuluka.Kuphatikiza apo, mayunitsi angapo a ku Europe ndi America adayima m'gawo loyamba ndi lachiwiri, zomwe zidapangitsa kutsika kwadzidzidzi, pomwe mayunitsi aku Asia anali pakukonzekera kukonza, ndipo mitengo yaku China inali yotsika kuposa mitengo yaku Asia, Europe ndi America, yomwe. anathandiza China acrylonitrile kunja kukula, kuphatikizapo Taiwan Province la China, pafupi Korea, India ndi Turkey.

Kuwonjezeka kwa kuchuluka kwa katundu wotumizidwa kunja kunatsagana ndi kukwera kwa chiwerengero cha mayiko omwe akutumiza kunja.M'mbuyomu, zinthu zaku China za acrylonitrile zidatumizidwa makamaka ku South Korea ndi India.2021, ndi kuchepa kwa zinthu zakunja, kuchuluka kwa katundu wa acrylonitrile kunakula ndikutumizidwa nthawi ndi nthawi kumsika waku Europe, kuphatikiza mayiko asanu ndi awiri ndi zigawo monga Turkey ndi Belgium.

Zikuyembekezeredwa kuti kukula kwa mphamvu yopanga acrylonitrile ku China m'zaka zikubwerazi za 5 ndizokulirapo kuposa kukula kwa kufunikira kwa kutsika kwa madzi, zogulitsa kunja zidzacheperachepera, pamene zogulitsa kunja zidzapitirira kuwonjezeka, ndipo kutumizidwa kunja kwa acrylonitrile ku China kukuyembekezeka. kukhudza matani 300,000 mu 2022, motero kuchepetsa kupanikizika kwa msika waku China.

chemwin amagulitsa zakudya zapamwamba kwambiri, zotsika mtengo za acrylonitrile zomwe zili padziko lonse lapansi
