Extruded Metal-organic Framework Materials and Methods For Production Thereof

Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced in powder form. Extrusion of powder-form MOFs to produce shaped bodies has heretofore proven difficult due to loss of surface area and poor crush strength of MOF extrudates, in addition to phase transformations occurring during extrusion. The choice of mixing conditions and the mixing solvent when forming MOF extrudates can impact these factors. Extrudates comprising a MOF consolidated material may feature the MOF consolidated material having a BET surface area of about 50% or greater relative to that of a pre-crystallized MOF powder material used to form the extrudate. X-ray powder diffraction of the extrudate shows about 20% or less conversion of the MOF consolidated material into a phase differing from that of the pre-crystallized MOF powder material.

20220169663 · 2022-06-02 ·

Metal-organic framework materials (MOFs) are highly porous entities comprising a multidentate organic ligand coordinated to multiple metal centers, typically as a coordination polymer. MOFs may comprise a plurality of metal centers, and a multidentate organic ligand coordinated via at least two binding sites to the plurality of metal centers to define an at least partially crystalline network structure having a plurality of internal pores, and in which the multidentate organic ligand comprises first and second binding sites bridged together with a third binding site comprising a diimine moiety. The multidentate organic ligand may comprise a reaction product of a vicinal dicarbonyl compound and an amine-substituted salicylic acid to define the first, second and third binding sites. Particular MOFs may comprise 5,59′-(((1E,2E)-ethane-1,2-diylidene)bis-(azaneylylidene))bis(2-hydroxybenzoic acid) as a multidentate organic ligand.

A process for preparing an extrudable composition comprising a titanium-containing zeolitic material having framework type MWW, the process comprising providing a titanium-containing zeolitic material having framework type MWW, having a water absorption capacity of at least 11 weight-%, subjecting the titanium-containing zeolitic material having framework type MWW an acid treatment, optionally incorporating zinc in the acid-treated titanium-containing zeolitic material having framework type MWW; preparing a composition comprising the titanium-containing zeolitic material having framework type MWW obtained from (ii) or (iii), a precursor of a silica binder, water, and a kneading agent, wherein the composition does not comprise a polyethylene oxide.

Solid-State Synthesis Of Precursors Of Metal-Organic Frameworks
20220089618 · 2022-03-24 ·

Metal-organic frameworks (MOFs) are highly porous entities comprising a multidentate ligand coordinated to multiple metal atoms, typically as a coordination polymer. MOFs are usually produced from a solvent in powder form under hydrothermal or solvothermal synthesis conditions. Alternately, powder-form precursors of MOFs may be formed by milling or mulling a substantially solid mixture of a metal salt and a multidentate organic ligand, optionally in the presence of a small amount of a solvent. The powder-form precursors may then undergo heating, typically in the absence of applied shear, to produce the corresponding MOF. Mulling may be differentiated from milling at least in that mulling applies to the substantially solid mixture at a non-constant pressure and milling applies a constant pressure while forming the powder-form precursor. In some cases, mulling may promote more effective formation of the powder-form precursor compared to milling.
