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.

专利号:US-10913702-B2 优先权日:2018-01-15 标 题:Method for cycloaddition of dimethyl muconate 发明人:PARK JAE KYUN; PARK JEONG HO; CHAE HEE-IL 权利人:SK CHEMICALS CO LTD 摘要:A method for cycloaddition of dimethyl muconate is disclosed. According to the method, a direct transferring of a solid phase trans,trans-dimehtyl muconate into a reactor pre-filled with ethylene gas increases the efficiency of the reaction and suppress side reactions resulting an improvements in yield and purity. Furthermore, the method is capable of obtaining a high yield of dimethylcyclohex-2-en-1,4-dicarboxylate at a lower cost, and therefore is also useful for the mass synthesis of dimethyl terephthalate.
