This invention relates to modified MOF materials, methods of preparing them and processes using them. A modified MOF of the invention is modified by impregnating a MOF with an inorganic metal salt. The starting MOF contains at least one linker or ligand which contains an aryl amino group as part of its structure. These modified MOFs are able to adsorb either basic or acidic toxic industrial compounds (TIC). The modified MOFs can be used to remove TICs from various gaseous streams such as air.

Modified metal-organic framework (MOF) compositions, process of making and process of use thereof

This invention relates to a method of using MOF adsorbents to remove elemental impurities from feed streams comprising active pharmaceutical ingredients (API). The process involves contacting the feed stream comprising API and elemental impurities with the MOF at purification conditions to obtain a purified stream with provides an API which has a concentration of the elemental impurity below its permitted daily exposure. The process can be carried in a batch mode where the MOF and feed stream are admixed in a vessel for a given amount of time or continuously by flowing the feed stream through a column or adsorbent bed containing the MOF adsorbent.

Metal organic frameworks for removal of elemental impurities in pharmaceutical products

A drive wheel has a generally cylindrical exterior surface with a circumferential groove. A block has a cylindrical working surface in sliding contact with the drive wheel, an operational face with an opening there through. A die is located in the opening and has an interior surface constituting a continuation of the working surface of the block. The die has an exit opening. A diverter is secured to the die and extends into the recess with a leading abutment edge positioned in operative proximity to the exit opening.
