Ts'ebetso ea Phthalic Anhydride ka Sehlahisoa sa Maleic Anhydride ke efe?

Mokhoa oa Phepelo ea Phthalic Anhydride
Ha ho hlahisoa anhydride ea phthalic ho tsoa ho o-xylene, anhydride ea maleic ke sehlahisoa se latelang (~5% ea tlhahiso ea anhydride ea phthalic). Nakong ea tlhahiso ea anhydride ea phthalic, khase ea mohatla oa karabelo e hlatsuoa ho tlosa lintho tse phelang; mokelikeli oa ho hlatsoa (o nang le anhydride ea maleic, bongata bo bonyenyane ba benzoic acid, le phthalic acid) oa teteana, oa hloekisoa, 'me MOLEMOe qhibilihisoa ho omisa metsi—e leng se hlahisang dihlahiswa tsa maleic anhydride.
