Ukulungiswa kunye noKwahlulwa
Emva kokwenziwa kwe-ester, ukulungiswa kuyadingeka ukuze kwahlulwe i-anhydride ye-maleic kwimveliso eziphuma kuyo. Le nkqubo ifuna izixhobo ezizinzileyo kunye nokusebenza okusemgangathweni. I-anhydride ye-maleic ehlukanisiweyo emva koko iyancipha ngakumbi, iguqulwe umbala, kwaye isuswe ukungcola ukuze kuphuculwe ubunyulu bayo kunye nomgangatho wayo.
Unyango lwegesi yenkunkuma
Ukuveliswa kwe-anhydride ye-maleic kuvelisa igesi eninzi engcolileyo (equlethe izinto eziphilayo ezifana ne-benzene kunye ne-carbon dioxide). Unyango kufuneka luhlangabezane nemigangatho yokusingqongileyo: izixhobo ezifanelekileyo kunye nemilinganiselo (umz., izinto ezifunxayo, ukutsha kwe-catalytic, okanye ii-adsorption towers) kufuneka zisetyenziswe ukususa izinto ezinobuthi, ukukhusela okusingqongileyo kunye nokhuseleko lwabasebenzi.
Ngamafutshane, iimfuno zobugcisa zokuveliswa kwe-anhydride ye-maleic zigubungela ukukhethwa kwezinto eziluhlaza, ukukhethwa kwe-catalyst, ulawulo lwemeko yokusabela, ulawulo lwe-esterification, ukulungiswa/ukwahlulwahlulwa, kunye nonyango lwegesi emdaka. Ulawulo lwenzululwazi nolwengqiqo lwale miba lwenza kube lula ukuvelisa ngempumelelo ngelixa kuqinisekiswa umgangatho wemveliso kunye nokhuseleko lokusingqongileyo.

Iminyaka Engamashumi Amabini Ikhokela Ukuthunyelwa KweeAnhydride ZeMaleic! Imveliso yeShandong Puli Chemical enokwandiswa, ulawulo oluqinileyo lomgangatho, kunye nezisombululo eziqala ekupheleni ukuya ekupheleni zigcina abathengi bephambili kwihlabathi liphela.
