Processes for producing an α,β-unsaturated carboxylic acid, such as acrylic acid, or a salt thereof, using solid promoters are disclosed. The starting material either is a metallalactone or comprises an olefin and carbon dioxide. The solid promoters can be certain solid oxides, mixed oxides, and clays, illustrative examples of which can include alumina, zirconia, magnesia, magnesium aluminate, sepiolite, and similar materials. |
