Removal of reaction by-products, including color bodies and metals, is a critical step in producing high quality pharmaceuticals and intermediates. Ecosorb® multi-functional adsorbents are a family of highly efficient adsorbents combining the rapid kinetics of fine particles with excellent filtration characteristics.
Ecosorb powders can be used in a stirred reactor, or as a precoat or deep bed operating mode, where the adsorbent is added directly to the filter, eliminating contamination of the reaction vessel. Formulations include moist versions, suitable for aqueous systems, as well as low-moisture versions suitable for organic solvents. Since each reaction/solvent system is unique, Graver provides a “sample kit” containing a broad range of adsorbent types for screening specific applications.
Ecosorb PAK® adsorbent cartridges are sold as a complete unit in Graver-supplied housings, or can be used in many commonly used filter housings with retrofit kits from Graver. Ecosorb PAK adsorbent cartridges eliminate reactor vessel and filter cleanup, and simplify the recovery of precious metals.
