摘要:The present invention relates to a method for the in situ synthesis of of MOFs (metal organic frameworks), COFs (covalent organic frameworks), and ZIFs (Zeolitic imidazolate framework), onto and within different types of porous substrates, and their applications. The present invention provides a unique and easy to utilize method by which a number of MOFs, COFs and ZIFs can be synthesized directly onto and within a porous substrate with high performance efficiency ensuring higher grammage in formation of adsorbent product onto and within the substrate.

标题:Solid-State Synthesis Of Precursors Of Metal-Organic Frameworks
发明人：MAJANO GERARDO J; FALKOWSKI JOSEPH M

摘要: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.

发明人：ABNEY CARTER W; IVASHKO ANNA C
权利人:EXXONMOBIL RES & ENG CO
摘要:A method suitable for use in investigating synthesis conditions for metal-organic frameworks may include: identifying synthesis conditions that includes a first solvent system by which a metal-organic framework is successfully synthesized; and synthesizing the metal-organic framework under substantially the same synthesis conditions but with a second solvent system (or a comparable solvent system) having a difference (R a ) between Hansen solubility parameters of 5 MPa 0.5 or less as compared to the first solvent system.
