    标题:Synthesis of certain bis(phthalic anhydrides)

    摘要:Monomeric high molecular weight dianhydrides or tetraacids can be produced by the nucleophilic coupling of a halo substituted phthalimides acid and an aliphatic or aromatic compound having polyfunctional groups capable of reacting with the halo moiety of the phthalinide followed by hydrolysis and dehydration. Specifically, 4-chlorophthalate sodium salt is converted to an imide to reduce side reactions with the carboxylic acid groups prior to reaction with 4,4'-disodiumdiphenylene oxide sulfone or 2,2-di (4-sodium phenoxide) propane. After the reaction of the imide and the sulfone or propane compounds, the diimide formed is converted to the corresponding dianhydride.
