Abstract: The present invention discloses processes for oligomerizing an olefin feedstock containing C4 to C20 alpha olefins using a catalyst system containing a metallocene compound, an organoaluminum compound, and a suspension of a chemically-treated solid oxide. The liquid medium for the suspension of the chemically-treated solid oxide can be an alpha-olefin oligomer product formed by the oligomerization process.

Abstract: This disclosure provides for routes of synthesis of acrylic acid and other ?,?-unsaturated carboxylic acids and their salts, including catalytic methods. For example, there is provided a process for producing an ?,?-unsaturated carboxylic acid or a salt thereof, the process comprising: (1) contacting in any order, a group 8-11 transition metal precursor, an olefin, carbon dioxide, a diluent, and a polyaromatic resin with associated metal cations to provide a reaction mixture; and (2) applying conditions to the reaction mixture suitable to produce the ?,?-unsaturated carboxylic acid or a salt thereof. Methods of regenerating the polyaromatic resin with associated metal cations are described.

For example, there is provided a process for producing an ?,?-unsaturated carboxylic acid or its salt, comprising: (1) contacting in any order, a group 8-11 transition metal precursor, an olefin, carbon dioxide, a diluent, and a porous crosslinked polyphenoxide resin comprising associated metal cations to provide a mixture; and (2) applying reaction conditions to the mixture suitable to produce the ?,?-unsaturated carboxylic acid or a salt thereof. Methods of regenerating the polyphenoxide resin comprising associated metal cations are described.

Abstract: Disclosed is a continuous process for producing ?,?-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 (CO2), 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 ?,?-unsaturated carboxylic acid and form a reacted solid. Methods of regenerating the polyanionic solid are described.
