ABSTRACT The invention relates to storage-stable solutions of mixtures of carbonated magnesium methylate of the formula Mg(CH3O)2 (CO2)n and carbonated magnesium ethylate of the formula Mg(C2H5O)2 (CO2)n and their carbonated mixed alkoxide of the formula Mg(CH3O)x (C2H5O)y (CO2)n in which 0 < x, y < 2 and x + y = 2, in a mixture of methanol and ethanol, and processes for their preparation. The magnesium content of the solution is 0.1 to 11% by weight, based on the total solution, and the CO2 content n is 1.2 to 2.2. The solutions according to the invention are used, inter alia, for the preservation of paper and for the preparation of catalysts for the polymerisation of olefins. They show an excellent storage stability, in that no discolouration, precipitation or gel formation occurs over long periods of time.
