Amine production core technologies
Gas-phase reaction technologies
We utilize gas-phase reactions to produce pyridines from acetaldehyde, formaldehyde, and ammonia, and we are one of the world’s most competitive producers of pyridines.
We draw on our long expertise in gas-phase reactions to provide amine products tailored to mass production.

High pressure reaction technology
Our firm specializes in reductive amination, alkylation of alcohols, hydrogenation of nitrile compounds, and hydrogenation of heteroaromatic rings.
Our various amines are produced through hydrogen-reduction reactions using metals as catalysts under high pressure.
