ABSTRACT:
A method is provided for making alkali metal bis-phenoxide salts by refluxing a heterogenous mixture of a non-polar organic solvent and an aqueous solution of an alkali metal bisphenoxide. These bisphenoxide salts can be used thereafter to make aromatic bis(ether phthalimides) by reaction with nuclear ring substituted N-organo phthalimides.
