I-Maleic anhydride (MA) iyinhlanganisela ebalulekile yemvelo esetshenziswa kabanzi embonini yamakhemikhali. Izicelo zayo eziyinhloko zihlanganisa ukukhiqizwa kwama-polyester resins (UPR), abalulekile ekukhiqizeni amapulasitiki aqiniswe nge-fiberglass, okokuhlanganisa, nezingxenye zezimoto. Ukwengeza, i-MA isebenza njengesandulela se-1,4-butanediol (BDO), esetshenziswa kumapulasitiki abolayo, nokunye okuphuma kokunye okufana ne-fumaric acid namakhemikhali ezolimo36.
Eminyakeni yakamuva, imakethe ye-MA ibe nokuguquguquka okukhulu. Ngo-2024, amanani ehle ngo-17.05%, aqala ku-7,860 RMB/ton futhi agcina ku-6,520 RMB/ton ngenxa yokutholakala ngokweqile kanye nesidingo esibuthakathaka esivela emkhakheni wezindlu ezithengiswayo, umthengi omkhulu we-UPR36. Kodwa-ke, ukunyuka kwamanani esikhashana kwenzeke ngesikhathi sokumiswa kokukhiqiza, njengokuvalwa okungalindelekile kwe-Wanhua Chemical ngoDisemba 2024, okwenyusa izintengo kafushane ngo-1,000 RMB/ton3.
Kusukela ngo-Ephreli 2025, amanani e-MA ahlala eguquguquka, namakhotheshini asukela ku-6,100 kuya ku-7,200 RMB/ton e-China, athonywe izici ezifana nezindleko zempahla eluhlaza (n-butane) kanye noshintsho lwesidingo esingezansi27. Imakethe kulindeleke ukuthi ihlale ngaphansi kwengcindezi ngenxa yokwanda kwamandla okukhiqiza kanye nesidingo esehlisiwe esivela emikhakheni yendabuko, noma ukukhula kwezinto zezimoto nezinto ezibolayo kunganikeza ukwesekwa okuthile.
