The invention relates to a method for producing an alkali or earth alkali salt of an alpha,beta-ethylenically unsaturated carboxylic acid, wherein a) an alkene, carbon dioxide and a carboxylation catalyst is reacted to form an alkene/carbon dioxide/carboxylation catalyst adduct, b) using an auxiliary base, the adduct is decomposed into the auxiliary base salt of the alpha,beta-ethylenically unsaturated carboxylic acid releasing the carboxylation catalyst, c) using an alkali or earth alkali metal base, the auxiliary base salt of the alpha,beta-ethylenically unsaturated carboxylic acid is reacted to form the alkali or earth alkali salt of the alpha,beta-ethylenically unsaturated carboxylic acid releasing the auxiliary base. Salts of alpha,beta-ethylenically unsaturated carboxylic acids, such as in particular sodium acrylate, are required in large quantities, for example, for producing water-absorbing resins.
