I-Adipic Acid Industry Chain
Iasidi yeAdipic yi-asidi ye-dicarboxylic ebalulekileyo kwimizi-mveliso, ekwaziyo ukusabela ngeendlela ezahlukeneyo, kubandakanywa ukubunjwa kwetyuwa, i-esterification, i-amidation, njl njl. Yeyona nto iphambili yokuvelisa i-nayiloni 66 ifayibha kunye ne-nayiloni 66 resin, i-polyurethane kunye ne-plasticizer, kwaye idlala indima ebalulekileyo kwimveliso yeekhemikhali, imboni ye-organic synthesis, iyeza, ukuveliswa kwe-lubricant, njl. Inkqubo yokuvelisa i-adipic acid ihlulwe kakhulu kwi-phenol, i-butadiene, i-cyclohexane kunye ne-cyclohexene iinkqubo.Okwangoku, inkqubo ye-phenol iye yapheliswa kakhulu, kwaye inkqubo ye-butadiene isekho kwinqanaba lophando.Okwangoku, ishishini lilawulwa yi-cyclohexane kunye ne-cyclohexene iinkqubo, kunye ne-benzene, i-hydrogen kunye ne-nitric acid njengezinto eziluhlaza.

Ubume boShishino lweAdipic
Ukusuka kwicala lonikezelo lwe-asidi ye-adipic yasekhaya, umthamo wemveliso we-adipic acid e-China ukhula ngokucothayo kwaye imveliso iyanda ngokucotha unyaka nonyaka.Ngokwezibalo, ngo-2021, amandla okuvelisa i-adipic acid yi-2.796 yezigidi zeetoni / ngonyaka, imveliso ye-adipic acid yi-1.89 yezigidi zeetoni, ukwanda kwe-21.53% ngonyaka, kunye nokuguqulwa komthamo ngu-67.60%.

Ukusuka kwicala lemfuno, ukusetyenziswa okubonakalayo kwe-adipic acid kunyuka ngokuqhubekayo kwinqanaba eliphantsi lokukhula ngonyaka ukusuka kwi-2017-2020.Ngokwezibalo, ngo-2021, imfuno esezantsi ye-PU paste iphinda ibuye kwaye ukusetyenziswa okubonakalayo kwe-adipic acid kukhula ngokukhawuleza, ngokusetyenziswa okubonakalayo ngonyaka kwe-1.52 yezigidi zeetoni, ukunyuka kwe-30.08% unyaka nonyaka.

Ukususela kwisakhiwo semfuno yasekhaya ye-adipic acid, i-PU i-akhawunti yokunamathisela i-akhawunti malunga ne-38.20%, i-akhawunti ye-soles ye-raw eluhlaza malunga ne-20.71% yemfuno epheleleyo, kunye ne-nylon 66 i-akhawunti malunga ne-17.34%.Kwaye iasidi yeadipic yamazwe ngamazwe isetyenziswa ikakhulu ukuvelisa inayiloni engama-66 yetyuwa.

Ukungenisa kunye nokuthumela kwelinye ilizwe imeko ye-adipic acid

Ukusuka kwimo yokungenisa kunye nokuthumela ngaphandle, ukuthunyelwa ngaphandle kwe-China ngaphandle kwe-adipic acid kukhulu kakhulu kunokungenisa ngaphandle, kwaye isixa sokuthumela ngaphandle siye sanyuka njengoko ixabiso lemarike ye-adipic acid liqhubeka nokunyuka.Ngokwezibalo, ngo-2021, inani lokuthumela ngaphandle kwe-adipic acid e-China yayiziitoni ezingama-398,100, kwaye imali yokuthumela ngaphandle yayizizigidi ezingama-USD ezingama-600.

Ukusuka ekusasazweni kweendawo ezithunyelwa ngaphandle, i-Asiya neYurophu zibalelwa kwi-97.7% yempahla ethunyelwa ngaphandle.Abathathu abaphezulu yiTurkey kunye ne-14.0%, iSingapore kunye ne-12.9% kunye neNetherlands kunye ne-11.3%.

Ipateni yokhuphiswano kwishishini le-adipic acid

Ngokumalunga nepateni yokhuphiswano lwemarike (ngomthamo), umthamo wemveliso ye-adipic yasekhaya ugxile kakhulu, kunye nabavelisi abahlanu abaphezulu be-adipic abalelwa kwi-71% yomthamo wemveliso welizwe.Ngokwezibalo, imeko ye-CR5 ye-adipic acid e-China ngo-2021 yile: I-Huafeng Chemical (iitoni ezingama-750,000, i-26.82%), i-Shenma Nylon (i-475,000 yeetoni, i-akhawunti ye-16.99%), i-Hualu Hensheng (i-326,000 yeetoni eziyi-11, i-akhawunti ye-6% yeetoni. ), Jiangsu Haili (300,000 tons, accounting for 10.73%), Shandong Haili (225,000 tons, accounting for 8.05%).

Indlela yophuhliso lwexesha elizayo yoshishino lwe-adipic acid

1. Umahluko wexabiso ukwizinga eliphezulu

Ngo-2021, ixabiso le-adipic acid libonise ukunyuka okunyukayo ngenxa yokunyuka kwexabiso lezinto eziluhlaza, kwaye ngoFebruwari 5, 2022, ixabiso le-adipic acid laliyi-13,650 yuan / ton, eyayikwimbali ephezulu.Ukuphenjelelwa lixabiso elikhulayo le-benzene ecocekileyo, ukusasazeka kwe-adipic acid kwehle kwimbali esezantsi kwisiqingatha sokuqala sika-2021, kwaye ukusukela ngo-Okthobha ka-2021, amaxabiso ezinto ezikrwada aye abuya umva kwaye i-adipic acid yanda ngokufanelekileyo.Ukusasazeka kwe-asidi ye-adipic yayiyi-RMB5,373/ton ngoFebruwari 5, 2022, iphezulu kunomyinge wembali.

I-2.PBAT kunye ne-nylon 66 imveliso yokuvuselela imfuno

Ngokubhengezwa kothintelo lweplastiki, i-PBAT yasekhaya ifuna ukukhula, iiprojekthi ezininzi ezisakhiwayo;ukongeza, indawo adiponitrile ukusombulula ingxaki inayiloni 66 intamo impahla ekrwada, phantsi kolwakhiwo kunye nokucwangciswa adiponitrile umthamo ngaphezu kwe-1 yezigidi zeetoni, ukukhululwa adiponitrile umthamo wasekhaya ukukhawulezisa inayiloni yasekhaya 66 wangenisa kwixesha ukukhula ngokukhawuleza. kwisikhundla, i-adipic acid iya kuzisa umjikelo omtsha wokukhula kwemfuno.

Okwangoku phantsi kolwakhiwo kunye nokucwangcisa umthamo we-PBAT ongaphezu kweetoni zezigidi ezili-10, apho i-4.32 yezigidi zeetoni kulindeleke ukuba ifakwe kwimveliso ngo-2022 kunye no-2023, itoni ye-PBAT idla malunga ne-0.39 yeetoni ze-adipic acid, eyenza imfuno ye-adipic acid. malunga ne-1.68 yezigidi zeetoni;phantsi kolwakhiwo kunye nokucwangcisa inayiloni 66 umthamo 2.285 yezigidi zeetoni, itoni inayiloni 66 idla malunga 0.6 iitoni adipic acid, ukwenza imfuno adipic acid malunga 1.37 yezigidi zeetoni.
