High pressure reaction technology
We utilize high pressure hydrogenation, such as reductive amination, alkylation of amines, amination of alcohol, nitrile hydrogenation, and nitrogen-containing aromatic compound hydrogenation, to synthesize wide variety of amines and nitrogen-containing heterocyclic compounds.
