Definitions

  • compositions in accordance with the invention a higher pH causes precipitation of the biocidal cation as a water insoluble basic salt. This problem can be avoided by the use of complexing agents which interact with the biocidal cation to form complexes and prevent insolubilisation of the cation at elevated pH.
  • Solution B(l) or B(2) may be applied to material still wet from treatment with Solution A either immediately or after a delay.
  • the pH was adjusted by varying the amount of sodium hydroxide in order to obtain compositions of pH 6.0,
  • Formulation 1 (Preferred composition in accordance with the invention) % W/W
  • R is a branched or straight-chain alkyl group.
  • the group R contains between 8 and 18 carbon atoms.

Abstract

L'invention se rapporte à une composition de conservation aqueuse, qui contient un cation biocide (qui peut être un cation libre ou peut être présent comme partie d'un complexe) et un ion de nitrite (qui peut être un anion libre ou peut être présent comme partie d'un complexe) et qui se caractérise par un pH supérieur à 6,5, à condition que lorsque le pH est supérieur à 9,25 et que la composition contient de l'ammoniac ou une amine, elle ne peut pas contenir un sel d'ammonium quaternaire. Des procédés de traitement du bois à l'aide de telles compositions sont également décrits.
