Abstract: The potential hazards of acraldhyde make its direct handling for combatting microbial, vegetable and animal pests in the water and ground difficult. According to the invention, use is made of a composition releasing acraldhyde in contact with water at the point of use. The composition of the invention contains an acraldhyde acetal, preferably 2-vinyl-2, 3-dioxolane, and a compound hydrolysable to an acid with a pK S of lower than 4, especially one from the range of organic acid anhydrides, organic acid halides and inorganic halogen compounds forming hydrogen halides on hydrolysis.

Abstract: The present invention relates to a process for producing postcrosslinked water-absorbing polymeric formations, comprising the steps of contacting water-absorbing polymeric formations P1 obtained by polymerization of ethylenically unsaturated acid-functional monomers or salts thereof in the presence of a crosslinker with a fluid F1 comprising a postcrosslinker, heating the water-absorbing polymeric formations in contact with the fluid F1 to a temperature in a range from 40 to 300° C. to obtain postcrosslinked water-absorbing polymeric formations P2, the water-absorbing polymeric formations P1 having a thermal stability, as determined in accordance with the test method described herein, of less than 3.0%. The invention also relates to water-absorbing polymeric formations, to the water-absorbing polymeric formations obtainable by this process, to water-absorbing polymeric formations based on crosslinked carboxyl-bearing monomers, to a composite comprising water-absorbing polymeric formations and a substrate, to a process for producing a composite, to a composite obtainable by this process, to chemical products comprising water-absorbing polymeric formations or a composite, to the use of water-absorbing polymeric formations or of a composite in chemical products and also to the use of triallyl isocyanurate as an internal crosslinker in the production of water-absorbing polymeric formations based on crosslinked carboxyl-bearing monomers.

Abstract: The agent contains an aqueous percarboxylic acid with 1 to 6 carbon atoms as peroxygen compound, to which ballast is added water in an amount corresponding to 0.1 to 200 mg percarboxylic acid per liter. Process for avoiding contamination of navigatable body of water with organisms selected from plankton, e.g. epifauna and photo plankton including cystenes, comprises adding reagent containing peroxygen compound to the ballast water, allowing the reagent to react until the organisms are destroyed and feeding the treated water back into the body of water.
