专利号:US-2022089618-A1 优先权日:2019-01-29 标题:Solid-State Synthesis Of Precursors Of Metal-Organic Frameworks 发明人:MAJANO GERARDO J; FALKOWSKI JOSEPH M 权利人:EXXONMOBIL RES & ENG CO 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.

The invention also relates to methods for preparing metal organic frameworks comprising chromium, titanium or iron ions and carboxylate ligands. The methods of the invention allow such metal organic frameworks to be prepared in monocrystalline or polycrystalline forms.
专利号:US-2016293932-A1 优先权日:2015-03-30 标题 :Synthetic methods for transition metal coordination compounds 发明人:MOTALLEBI SHAHROKH; RISSET OLIVIA NATHALIE; WESSELLS COLIN DEANE 权利人:ALVEO ENERGY INC 摘要:A system and method for controlling particle morphology of transition metal coordination compounds (TMCC). Synthesis of TMCC using one of several chelating agents having carboxylate chemical groups. These carboxylate groups bind to copper during the synthesis of the CuHCF TMCC materials, resulting in controlled particle growth, rather than rapid formation of many small nanoparticles as is the case without any chelating agent present. The materials produced using chelating agents of these embodiments such as these are composed of larger particles, making them easier to process into battery electrodes via standard methods such as slurry mixing and coating. The resulting electrodes retain the good electrochemical cycling performance of the control material synthesized without a chelating agent.

专利号:US-10487406-B2 优先权日:2013-12-27 标 题:Bis-imidazoline compounds as corrosion inhibitors and preparation thereof 发明人:GULABANI RITESH; KING STEPHEN W; DICHOLKAR DEEPAK; KU SUNG-YU 权利人:DOW GLOBAL TECHNOLOGIES LLC 摘要:The disclosure provides compositions and methods for inhibiting corrosion of a copper surface using a bis-imidazoline compound having an aromatic group, such as an aryl bis-imidazoline. The bis-imidazoline corrosion inhibitor can provide one or more advantage in use such as synergistic performance in aqueous and acidic media at low active dosages, resistance to decomposition or degradation in the presence of harsh reagents, ease of dispersion in an aqueous system, and improved thermal stability over conventional triazole based inhibitors. The disclosure also provides methods for the synthesis of bis-imidazoline compounds.
