Synthesis and characterization of new aromatic hydroxy acid compounds

Abstract

Four novel aromatic hydroxy acid (HA) compounds N-(4-hydroxyphenyl)-4’-trimellitimide,              N-(3-hydroxyphenyl)-4’-trimellitimide,  N-(5-hydroxynaphthyl)-4’-trimellitimide and  N-{4’-[2-(4-hydroxyph- enyl) isopropyl phenyl]}-4’’-trimellitimide are synthesized through  nucleophilic substitution reaction of trimelitic dianhydrides with the corresponding aminophenol/aminonaphthol using polar aprotic solvents. The hydroxy acid compounds are characterized by FT-IR and ¹H-NMR spectroscopy.
