  • Patent number: 11813589
    Abstract: In an improved superabsorbent complexed with aluminum ions, the aluminum ions are applied in the form of an aqueous solution comprising aluminum ions, which has the feature that it comprises aluminum ions in a proportion within the range of 0.5%-15% by weight (converted if appropriate to Al3+), based on the total mass of the solution, and further comprises anions of lactic acid (lactate ions) and phosphoric acid (phosphate ions), where the molar proportion of the lactate ions is within the range of 0.01-2.99 times the molar amount of Al3+ and the molar proportion of the phosphate ions is within the range of 0.01-2.99 times the molar amount of Al3+.

  • Publication number: 20130299739
    Abstract: The invention relates to a process for producing surface postcrosslinked water-absorbing polymer particles, wherein the water-absorbing polymer particles are coated, before, during or after the surface postcrosslinking, with at least one basic salt of a trivalent metal cation and a monovalent carboxylic acid anion, wherein the basic salt is applied in the form of a solution that is stabilized by a vicinal diol and/or an amide of the formula R1—CO—NR2R3 where R1 is not H and in which R1 is not H2N— if both R2 and R3 are H. Further, the invention relates to solutions of at least one basic salt that are stabilized by a vicinal diol and/or an amide of the formula R1—CO—NR2R3 where R1 is not H and in which R1 is not H2N— if both R2 and R3 are H.
