CASE PROJECTS

 

1. Continuous Hydrogenation of Benzene (Pyridine) Carboxylic Acid 

 

Products from hydrogenation of benzene (Pyridine)carboxylic Acid are widely used as active pharmaceutical ingredients (API).  Many producers use batch reactor hydrogenation because of the simplicity of the operation.  However, the batch mode needs very big volume of reactor, resulting very low volumetric yield.  In order to increase the reaction efficiency and to fit into an automatic operation in large scale production, continuous mode is desired.

 

For these reactions, the catalysts are usually chosen from Ni, Pt, Pd, and Rh supported on active carbon.  Also, the starting reactant is generally a high-melting point solid, a proper solvent is needed.  The solvent candidate could be from supercritical CO2, acetic acid, hexane, etc.  A batch reactor (autoclave) is used to obtain the kinetics of the reaction.  With the rate equation, a continuous reaction system is designed for process confirmation and engineering scale up  with a 2-liter continuous hydrogenation reactor-control system.  A proper catalyst and solvent for different reaction systems were chosen, Separation, purification of reactant-production for the hydrogenation of various starting materials were also determined for the production of products good for API specs.
