METHOD FOR THE PREPARATION OF AN ALUMINIUM TRIFORMATE SOLUTION CONTAINING ALKALI METALS AND/OR ALKALINE-EARTH METALS, HIGHLY CONCENTRATED ALUMINIUM TRIFORMATE SOLUTIONS CONTAINING ALKALI METALS AND/OR ALKALINE-EARTH METALS, AND THE USE OF SUCH SOLUTIONS

摘要

The invention concerns a method of preparing preferably highly concentrated aluminium triformate solutions containing alkali metals and/or alkaline-earth metals by the neutralization of an alkaline aluminate solution containing alkali metals and/or alkaline-earth metals by adding formic acid and subsequently heating the solid precipitated to give a clear, stable aluminium triformate solution. The invention also concerns highly concentrated aluminium triformate solutions containing alkali metals and/or alkaline-earth metals and the use of such solutions to impregnate textiles, in disinfectant and cleaning agents, as a coagulant for paints or as a setting agent in leather processing.
