WERKWIJZE VOOR HET BEREIDEN VAN AROMATISCHE ETHERIMIDEN.

摘要

A method for making aromatic ether imides is provided by effecting the displacement of reactive radicals on a phthalimide nucleus with a mono- or bis-alkali metal phenoxide in the presence of a nonpolar solvent and a phase transfer catalyst, such as a tetra-ammonia salt. The aromatic ether imides made by the present invention are useful intermediates for making aromatic ether anhydrides and aromatic bis(ether anhydrides).
