I-Adipic Acid Industry Chain
Adipic acid yi-acidic dicarboxylic ebalulekileyo kwezoshishino, ekwaziyo ezahlukeneyo reactions, kuquka ukwakheka ityuwa, esterification, amidation, etc. Yeyona nto iphambili ekrwada imveliso inayiloni 66 ifayibha kunye nenayiloni 66 resin, polyurethane kunye plasticizer, kwaye idlala indima ebalulekileyo kwimveliso yeekhemikhali, organic synthesis industry, amayeza, etc inkqubo yokwahlula-hlula imveliso ye-asidi ye-adipic. phenol, butadiene, cyclohexane kunye neenkqubo ze-cyclohexene. 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 (i-750,000 yeetoni, i-accounting ye-26.82%), i-Shenma Nylon (i-475,000 yeetoni, i-accounting ye-16.99%), i-Hualu Hensheng (i-326,000 yeetoni eziyi-6, i-accounting ye-11% ye-Jisuang, i-accounting ye-11%). (Iitoni ezingama-300,000, i-akhawunti ye-10.73%), i-Shandong Haili (iitoni ezingama-225,000, i-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 kwezigidi 1 iitoni, ukukhululwa adiponitrile umthamo wasekhaya ukukhawulezisa inayiloni yasekhaya 66 wangenisa kwixesha ukukhula ngokukhawuleza umthamo, adipic acid iya kuzisa umjikelo omtsha wokukhula.

Okwangoku phantsi kolwakhiwo kunye nokucwangcisa umthamo we-PBAT ongaphezu kwe-10 yezigidi zeetoni, apho i-4.32 yezigidi zeetoni kulindeleke ukuba ifakwe kwimveliso kwi-2022 kunye ne-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.
