Abstract
A method is disclosed for the preparation of salts of monoesters of the carbonic acid, the improvement consisting in that the alcohols corresponding to the esters are reacted with carbon dioxide and a compound of an alkali metal or an alkaline earth metal. A distinct advantage over the use of the alcoholates is obtained inasmuch as the reaction is less violent, side-reactions are put aside and the costs are lowered.
