Continuous Production of Active Pharmaceutical Ingredients
The present invention is directed to a method of producing active pharmaceutical ingredients (APIs). The method includes subjecting a reaction mixture with an API precursor to solvent extraction to produce a reactant stream with the API precursor. The method includes concentrating the API precursor in the reactant stream using at least one membrane. The method includes carrying out a reaction in a membrane reactor. The method includes separating the API precursor from the reaction stream using a separator. The method includes crystallizing the API precursor using a crystallizer to produce APIs.

Catalyst in which metal is carried on inorganic porous body having hierarchical porous structure, and method for manufacturing said catalyst
A catalyst includes a carrier, and a metal obtained by reducing a metal ion supported on the carrier 1) in a supercritical state or 2) in a polar organic solvent, wherein the carrier is an inorganic porous body having a hierarchical porous structure. By employing the catalyst, it is possible to exhibit better catalytic activity than a conventional catalyst. Heat generation and spontaneous ignition are prevented because no organic porous body is used.
