Zingaphi iinkqubo zemveliso yemizi-mveliso ezikhoyo ze-anhydride ye-maleic?

Iindlela Zokulungiselela
Okwangoku, kukho iinkqubo ezimbini eziphambili zemveliso yemizi-mveliso I-Maleic Anhydride:
Inkqubo yokunyibilikisa i-benzene: Isebenzisa i-benzene njengezinto eziluhlaza, i-maleic anhydride iveliswa nge-air oxidation phantsi kokuba kukho i-catalyst. Le nkqubo yamkelwe kakhulu eTshayina.
Inkqubo yokuxovwa kwe-n-Butane: I-anhydride ye-Maleic iveliswa nge-oxidation yomoya ye-n-butane ene-catalyst. Le nkqubo yahlulwe ngokweteknoloji yebhedi esisigxina kunye neyebhedi enyibilikisiweyo ngokusekelwe kuhlobo lwe-reactor. Kwicandelo emva konyango, kusetyenziswa iindlela ezimbini zobugcisa: ukufunxwa kwamanzi kunye nokufunxwa kwe-solvent.

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!
