Iyintoni inkqubo ye-Phthalic Anhydride By Product Maleic Anhydride?

Inkqubo yePhthalic Anhydride Byproduct
Xa kuveliswa i-anhydride ye-phthalic kwi-o-xylene, i-anhydride ye-maleic yimveliso ephumayo (~5% yemveliso ye-anhydride ye-phthalic). Ngexesha lokuveliswa kwe-anhydride ye-phthalic, igesi yomsila we-reaction iyahlanjwa ukuze kususwe izinto eziphilayo; ulwelo lokuhlamba (oluqulethe i-anhydride ye-maleic, ubungakanani obuncinci be-benzoic acid, kunye ne-phthalic acid) luyaxutywa, luhlanjululwe, kwaye KULUNGILEinyibilike ukuze ikhuphe amanzi emzimbeni—ivelisa iimveliso ze-anhydride ye-maleic.

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!
