Abstract
The invention relates to the thechnology of preparation N-substituted naphthalimides. A process for the preparation of N-carboxyphenylimides of 4-dimethylaminonaphthalene-1,8-dicarboxylic acid is based on interaction of corresponding N-carboxyphenylimide of 4-halonaphthalene-1,8-dicarboxylic acid with amine in solvent medium at elevated temperature. N-carboxyphenylimide of 4-chloronaphthalene-1,8-carboxylic acid or sodium salt thereof is used as N-carboxyphenylimide of 4-halonaphthalene-1,8-dicarboxylic acid, dimethylamine is used as amine and water is used as a solvent.
