Abstract
A method of acrylate salt production includes reacting ethylene gas in the presence of a metal precursor solution including a base, an additive, a metal precursor, a solvent and a ligand, in an autoclave, to form a metal complex intermediate solution. Further, COreacts with the metal complex intermediate solution to form an ester intermediate solution, which is reacted to form an acrylate salt product mixture. The acrylate salt is extracted thereafter. The COis reacted at a temperature in a range from 100° C. to 200° C., where 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. The additive is sodium formate and the solvent is selected from the group consisting of N-cyclohexyl-2-pyrrolidone, tetrahydrofuran, and combinations thereof. The turnover number is greater than or equal to 100.
