Abstract
A process for the production of organic acids having at least three carbon atoms comprises the steps of forming an amount of carbon monoxide and reacting the amount of carbon monoxide with an amount of an unsaturated hydrocarbon. The reaction is preferably carried out in the presence of a supported palladium catalyst, a strong acid, and a phosphine. In some embodiments, the unsaturated hydrocarbon is one of acetylene and methylacetylene, and the organic acid is one of acrylic acid and methyl acrylic acid. The reacting step is preferably performed with carbon monoxide produced from carbon dioxide.
