Abstract
Process for the production of carbonic acids, characterized in that the production thereof is made of olefins, preferably of branched olefins in the double bond and carbon dioxide in the presence of catalysts containing boric fluoride and inorganic acids, making the double decomposition in liquid phase first without addition of water in the presence of monooxyfluoride boric acid or its mixtures with phosphoric acid or sulfuric acid containing little or no water, only adding then the stoichiometric amount of water necessary for double decomposition.
