  • Patent number: 10994259
    Abstract: Novel crystalline porous materials known as metal-organic frameworks (MOFs) and methods for their synthesis are provided herein. The MOFs include a M6(?3-OH)8(OH)8(?2,?2-(O2C)2cyclam)8 cluster, and a metal atom coordinated to the one or more cyclam of the cluster, wherein M is Zr or Hf, and the metal atom is any one of Cu, Ni, Cr, Ru, Co, and Gd. The MOFs can be used as an adsorbent, alone or in a medium with other components, of CO2. The MOFs can also be used as a catalyst for the transformation of CO2 and epoxides to cyclic carbonates. The MOFs can also be used in the electrochemical catalytic reduction of CO2. The MOFs can also be used for photocatalytic CO2 reduction for the production of carbon-based fossil fuels. The MOFs can also be used for light-induced nitric oxide (NO) release. The MOFs can also be used as magnetic resonance imaging (MRI) agents.

  • Publication number: 20080119665
    Abstract: A process for the synthesis of zirconium tetra carboxylates is disclosed. To overcome the disadvantageous characteristics of the currently used production process, which include highly corrosive starting substances and products, and complex removal of HCl, ZrCI4 is suspended in an apolar solvent and reacted with the anhydride of an organic acid. The sole products of this reaction are slightly corrosive Zr tetra carboxylate and an organic acid chloride, which is a valuable basic chemical in the chemicals and pharmaceuticals industry. The reactors required for the synthesis need not necessarily consist of glass and/or enamel, but may instead be manufactured from stainless steel, which is cheaper. Apparatuses for the removal and treatment of hydrochloric acid are not necessary.
