摘要:The present invention relates to a process for the preparation of α,β-unsaturated carboxylic acids or salts thereof, by reaction of an olefin which has 2 or 3 carbon atoms with carbon dioxide in the presence of a catalyst which has an element E of groups 4, 6, 7, 8, 9 or 10 of the Periodic Table of the Elements, optionally a solvent and a salt which has a halide anion, which is characterized in that the reaction takes place in the presence of a medium-strength base, with the proviso that the medium-strength base is different from the salts used and any solvents present.

摘要:Catalysts and catalytic processes for the synthesis of acrylic acid and other α,β-unsaturated carboxylic acids and their salts, which are carried out in a diluent or in the absence of a diluent. In an aspect, ethylene and CO2 can be contacted with a Group 8-11 transition metal precursor compound or a Group 8-11 transition metal metalalactone compound in the presence of a metal-treated chemically-modified solid oxide (MT-CMSO) or a metal-treated solid oxide (MT-SO), to form a metal acrylate. As the catalytic activity wanes in either the presence or absence of a diluent, pressure cycling—that is, pressurizing the reaction system with CO2 and an olefin such as ethylene for a time period, releasing the pressure, then re-pressurizing with CO2 and ethylene—can rejuvenate the catalyst and restore its declining catalytic activity.
