m-phenylenediamine (m-PDA)

Amino-Chem adopts the world-class processes and equipment to achieve the continuous, automatic (100% DCS), safe and clean production.

Through the production of m-PDA, Amino-Chem has built a product portfolio with core technologies of continuous nitration, low-pressure liquid phase hydrogenation, rectification, etc. With the optimized design and the application of DCS, the company achieves the intrinsic safety of equipment.

Change of capacity of m-Phenylenediamine (m-PDA) from 2003 to 2015.

p-phenylenediamine (p-PDA)

Amino-Chem has two p-PDA production lines, in which benzene and p-nitroaniline are used as raw materials respectively. Both processes are based on the liquid-phase hydrogenation to obtain the final product of high quality and diverse grades.

Change of capacity of p-Phenylenediamine (p-PDA) from 2004 to 2015.


Amino-Chem developed a novel process, hydrolysis of m-PDA, to produce resorcinol by group R&D center.

Change of capacity of resorcinol from 2008 to 2015.
