General description

m-Phenylenediamine (MPD) is an aromatic diamine. It copolymerizes with iso- or terephthaloyl chloride and 3,5-diaminobenzoic acid or 2,4-diaminobenzene sulfonic acid (or sulfonate) to afford copolyamides by low temperature solution polymerization. MPD has been reported to be formed selectively during the hydrogenation of m-dinitrobenzene in the presence of bimetallic Ni-Pt catalysts supported on carbon. Cyclic voltammetric method has been proposed to study the electrochemical copolymerization of aniline with MPD in sulfuric acid solution.

Application

m-Phenylenediamine may be used in the synthesis of the following:
  • intrinsically electrically semiconducting microparticles of semiladder poly(m-phenylenediamine-co-2-hydroxy-5-sulfonic aniline) structures
  • extraction medium based on chitosan-poly(m-phenylenediamine) (CS-PPD) Fe3O4 nanocomposite, used as sorbent for the magnetic solid-phase extraction (MSPE) of polychlorinated biphenyls
  • series of terpolymers, via chemical oxidative polymerization
  • thin film composite (TFC) membranes based polyamide
  • TFC reverse osmosis (RO) membranes
