The catalytic hydrogenation technology of m-dinitrobenzene in liquid phase is an attractive and elegant routine for the production of m-phenylenediamine, owing to the advantages such as high product yield, good product quality and much less pollution to environment.

Electrochemical and Spectroelectrochemical Study of m-Phenylenediamine;

Research on Synthesis of m-Aminophenol by Hydrolysis of m-Phenylenediamine;

The effect of La_2O_3 and K_2O introducing methods on the catalytic performance of Ni/SiO_2 catalyst for m-dinitrobenzene hydrogenation to m-phenylenediamine were investigated,and the physical and chemical properties of the catalysts were analyzed by the techniques of BET,X-ray diffraction(XRD) and temperature-programmed reduc.

The liquid phase hydrogenation of m dinitrobenzene to m phenylenediamine was studied over these catalysts in a stainless steel autoclave.

The chemical reduction techology of m dinitrobenzene to m phenylenediamine were briefly introduced, and the liquid phase catalytic hydrogenation technology were reviewed in detail.

The optimum condition is that the mole ratio of maleic anhydride and m-phenylene diamine is 2.

The N,N-m-phenylene dimalemide is synthesized from maleic anhydride and m-phenylene diamine with acetic anhydride for the retarder,and the method of azeotropic dehydration is used with toluene as soluents.

Reverse osmosis composite membrane was prepared by interfacial polymerization(IP)of metaphenylene diamine(MPD)with trimesoyl chloride(TMC)on the surface of polysulfone(PS)support.
