Abstract:
Disclosed is a continuous process for producing α,β-unsaturated carboxylic acids or salts thereof, comprising: 1) in a first stage, contacting (a) a transition metal precursor compound comprising at least one first ligand, (b) optionally, at least one second ligand, (c) an olefin, (d) carbon dioxide (CO 2 ), and (e) a diluent to form a first composition; 2) in a second stage, contacting a polyanionic solid with the first composition to form a second composition; and 3) in a third stage, (a) contacting the second composition with a polar solvent to release a metal salt of an α,β-unsaturated carboxylic acid and form a reacted solid. Methods of regenerating the polyanionic solid are described.

Claim (Index 1):
A continuous process for producing an \u03b1,\u03b2-unsaturated carboxylic acid or salt thereof, the process comprising\n 1) in a first stage, contacting (a) a transition metal precursor compound comprising at least one first ligand, (b) optionally, at least one second ligand, (c) an olefin, (d) carbon dioxide (CO 2 ), and (e) a diluent to form a first composition; and 2) in a second stage, contacting a polyanionic solid with the first composition to form a second composition; and 3) in a third stage, (a) contacting the second composition with a polar solvent to release a metal salt of an \u03b1,\u03b2-unsaturated carboxylic acid and form a reacted solid; and (b) contacting the reacted solid with a metal-containing base to produce a regenerated polyanionic solid.
