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.

A novel method of synthesizing m phenylene diamine from m dinitrobenzene and iron powder was introduced in this paper.

Selenium-Catalyzed Reduction of m-Dinitrobenzene to m-Nitroaniline With Hydrazine Hydrate;

Phase transfer catalysis for the fluorodenitration of m-dinitrobenzene with spray-dried KF(SD-KF) in the presence of phthaloyl chloride(PDC) was reported.

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 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.
