AQUEOUS SOLUTIONS CONTAINING A COMPLEXING AGENT IN HIGH CONCENTRATION |
| 摘要 |
Aqueous solution comprising (A) in the range of from 30 to 60% by weight of a complexing agent, selected from the alkali metal salts of methylglycine diacetic acid and the alkali metal salts of glutamic acid diacetic acid, (B) in the range of from 700 ppm to 7% by weight of a polymer being selected from polyamines, the N atoms being partially or fully substituted with CH2COOH groups, partially or fully neutralized with alkali metal cations, ppm and percentages referring to the total respective aqueous solution |

1. An aqueous solution comprising:
a complexing agent in a range of 30% to 60% by weight, wherein the complexing agent is at least one selected from the group consisting of an alkali metal salt of methylglycine diacetic acid and an alkali metal salt of glutamic acid diacetic acid, a polymer in a range of 700 ppm to 7% by weight, wherein the polymer is a polyamine with N atoms being partially or fully substituted with CH2COOH groups, which are partially or fully neutralized with alkali metal cations, wherein ppm and percentages are based on the total weight of the aqueous solution. |
