Catalytic method for acrylate production

A method of acrylate salt production, comprising:

• reacting, in an autoclave, ethylene gas in the presence of a metal precursor solution comprising a base, an additive, a metal precursor, a solvent and a ligand to form a metal complex intermediate solution;
• reacting, in the autoclave, CO2 with the metal complex intermediate solution at a reaction temperature to form an ester intermediate solution;
• reacting the ester intermediate solution at a reaction temperature to form an acrylate salt product mixture;
• extracting an acrylate salt from the acrylate salt product mixture with water,
• wherein the reaction temperature is in a range from 100 to 200° C.,
• wherein the metal precursor is tetrakis(triphenylphosphine)palladium(0) and the concentration of tetrakis(triphenylphosphine)palladium(0) in the metal precursor solution is in a range from 0.0005M to 0.003M,
• wherein the additive is sodium formate,
• wherein the solvent is selected from the group consisting of N-cyclohexyl-2-pyrrolidone, tetrahydrofuran, and combinations thereof, and
• wherein a turnover number is greater than or equal to 100, wherein the turnover number is defined as the moles of acrylate salt formed per mole of catalyst.
