Acrylonitrile amapangidwa pogwiritsa ntchito propylene ndi ammonia monga zopangira, kudzera mukuchita kwa okosijeni ndi njira yoyenga. Ndi organic pawiri ndi chilinganizo mankhwala C3H3N, madzi opanda colorless ndi fungo lopweteka, kuyaka, nthunzi yake ndi mpweya akhoza kupanga kuphulika osakaniza, ndipo n'zosavuta kuyambitsa kuyaka pamene poyera lawi lamoto ndi kutentha kwakukulu, ndi zimatulutsa mpweya wapoizoni, ndipo amachitira mwachiwawa ndi oxidizers, zidulo amphamvu, zolimba zapansi 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 ulusi kupanga), ndi kumwa kunsi kwa mtsinje wa acrylonitrile ku China anaikira mu ABS, acrylic 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, matani 260,000 akugwira ntchito pa chaka chimodzi. anafika matani 910,000/chaka, ndipo okwana zoweta acrylonitrile mphamvu yafika 3.419 miliyoni matani/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 130,000 matani / 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, komanso ndi yabwino kwambiri kutumiza kunja ndi nyanja.

Kuwonjezeka kwakukulu kwa kupanga kumabweretsa kukwera kwa kupanga. Ziwerengero za Jinlian zikuwonetsa kuti kupanga acrylonitrile ku China kudapitilirabe kukulitsa zatsopano mu 2021. Pofika kumapeto kwa Disembala 2021, kuchuluka kwa zoweta zamtundu wa acrylonitrile kudapitilira matani miliyoni 2.317, mpaka 19% pachaka, pomwe kugwiritsidwa ntchito kwapachaka kunali pafupifupi matani 2.6 miliyoni, ndi zizindikiro zoyambirira zamakampani.

Chitukuko chamtsogolo cha acrylonitrile

M'chaka cha 2021 posachedwapa, malonda a acrylonitrile adadutsa kunja kwa nthawi yoyamba. Chiwerengero chonse cha zinthu za acrylonitrile chaka chatha chinali 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. Komanso, angapo mayunitsi European ndi America anaima mu kotala woyamba ndi wachiwiri, chifukwa cha kugwa mwadzidzidzi mu kupereka, pamene mayunitsi Asian anali mu anakonza mkombero yokonza, ndi mitengo Chinese anali m'munsi kuposa Asia, European ndi America mitengo, amene anathandiza China acrylonitrile zogulitsa 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 mwa apo ndi apo kumsika waku Europe, kuphatikiza mayiko asanu ndi awiri ndi zigawo monga Turkey ndi Belgium.

Akunenedweratu kuti kukula kwa mphamvu yopanga acrylonitrile ku China m'zaka 5 zikubwerazi ndi yayikulu kuposa kukula kwa kufunikira kwa kunsi kwa mtsinje, zotuluka kunja zidzacheperachepera, pomwe zotumiza kunja zipitilira kuwonjezeka, ndipo tsogolo la acrylonitrile ku China likuyembekezeka kukhudza kwambiri matani 300,000 mu 2022, motero kuchepetsa kukakamiza kwa msika ku China.

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