Polymerization of aniline derivatives by K₂ Cr₂ O₇ and production of Cr₂ O₃ nanoparticles

Oxidative polymerization of aniline, anthranilic acid, and aniline-co-anthranilic acid by potassium dichromate Cr(VI) as an oxidant in acidic medium was investigated. In this study, the polymerization process of aniline, o-anthranilic acid as well as aniline/o-anthranlic acid using K2Cr2O7 produced, coordinated Cr(III)/polyaniline (PANI), Cr(III)/polyanthranilic acid (PAA) and Cr(III)/poly aniline-co-anthranilic acid (PANAA). The mechanism of...
