| abstract |
The present invention relates to nonaqueous liquid formulations of aminoalkylenephosphonic acids and their corresponding salts, and to a process for the preparation thereof and their use for the preparation of homogeneous solutions in low molecular weight mono- and / or dihydric alcohols, the liquid formulation containing at least the following components: a) an aminoalkylenephosphonic acid or its corresponding alkali metal salt, having a content in the range from 5 to 35% by mass, b) a polyhydric alcohol having a C 2 to C 6 carbon skeleton, c) a solubilizer, wherein the mass ratio of polyhydric alcohol to solubilizer in the range of 80: 2 to 60:20 and process for producing them, wherein particularly advantageously the remaining amount of water in the liquid formulation is below a concentration limit, which is disadvantageous for further technical application Impact. |
