Maleic anhydride (MA) yog ib qho tseem ceeb ntawm cov organic compound dav siv hauv kev lag luam tshuaj. Nws cov ntawv thov tseem ceeb suav nrog kev tsim cov khoom siv tsis zoo polyester resins (UPR), uas yog qhov tseem ceeb hauv kev tsim fiberglass-reinforced plastics, coatings, thiab automotive qhov chaw. Tsis tas li ntawd, MA ua haujlwm ua ntej rau 1,4-butanediol (BDO), siv hauv biodegradable plastics, thiab lwm yam derivatives xws li fumaric acid thiab tshuaj ua liaj ua teb36.
Nyob rau hauv xyoo tas los no, MA kev lag luam tau muaj kev hloov pauv loj. Xyoo 2024, cov nqi poob qis los ntawm 17.05%, pib ntawm 7,860 RMB / tuj thiab xaus ntawm 6,520 RMB / ton vim yog kev xa khoom ntau dhau thiab tsis muaj zog xav tau los ntawm kev lag luam vaj tsev, cov neeg siv khoom loj ntawm UPR36. Txawm li cas los xij, tus nqi nce ib ntus tau tshwm sim thaum lub sijhawm tsim khoom nres, xws li Wanhua Chemical qhov kev cia siab tsis tau kaw thaum Lub Kaum Ob Hlis 2024, uas luv luv nqa tus nqi los ntawm 1,000 RMB / ton3.
Raws li lub Plaub Hlis 2025, MA cov nqi tseem tsis hloov pauv, nrog cov lus hais los ntawm 6,100 txog 7,200 RMB / tuj hauv Suav teb, cuam tshuam los ntawm cov khoom xws li cov khoom siv raw (n-butane) cov nqi thiab cov nqi qis qis dua 27. Kev ua lag luam yuav tsum nyob twj ywm nyob rau hauv kev ntxhov siab vim muaj peev xwm ntau lawm thiab subdued xav tau los ntawm ib txwm sectors, txawm hais tias kev loj hlob ntawm tsheb thiab biodegradable cov ntaub ntawv yuav muab ib co kev txhawb nqa.
