Ziziphi iinkqubo zokwenziwa kwe-anhydride ye-maleic kwamanye amazwe?

Iinkqubo zokwenziwa kweeNdawo zangaphandle
Imizi-mveliso yangoku I-Maleic Anhydride Iindlela zemveliso ikakhulu zisekelwe kwi-benzene, i-n-butane, i-C4 olefin, kunye ne-phthalic anhydride ephuma kwimveliso.
IBenzene ibisoloko iyinto eqhelekileyo yokwenza i-anhydride ye-maleic, kodwa izixhobo ezinqongopheleyo zebenzene ziye zaqhuba uphuhliso lweendlela ze-C4 olefin kunye ne-n-butane. Amazwe atyebileyo ngegesi yendalo kunye negesi enxulumene ne-oyile (ebonelela nge-n-butane eninzi) aye andisa ngokukhawuleza iinkqubo ze-n-butane—ngoku ezimalunga ne-80% yamandla emveliso yehlabathi.

Kutheni ukhetha iMaleic Anhydride? Yisiseko seeresini zepolyester ezingagcwaliyo eziphezulu, kwaye ivula iikhemikhali ezahlukeneyo ezisezantsi (i-BDO, i-THF, njl.njl.). Sithumelele umyalezo ngoku ukuze uhlole izisombululo ze-MA ezenzelwe ishishini lakho!
