The invention relates to a method for the preparation of aqueous solutions containing performic acid formed by reaction of formic acid and hydrogen peroxide in the presence of a catalyst, wherein the catalyst is a compound containing at least one ester group and/or group (a) differing from a carboxylic acid group and an alcoholic group, preferably a carboxylic acid ester. The invention also comprises aqueous solutions containing performic acid, formic acid, hydrogen peroxide, and a compound containing at least one ester group and/or group (a) differing from a carboxylic acid group, and the use of such solutions.
Procédé de préparation de solutions aqueuses renfermant de l'acide performique obtenu par mise en réaction d'acide formique et d'eau oxygénée en présence d'un catalyseur, le catalyseur étant un composé renfermant au moins un groupe ester et/ou un groupe (a) différent d'un groupe d'acide carboxylique et un groupe alcoolique, de préférence un ester d'acide carboxylique. On a également prévu des solutions aqueuses renfermant de l'acide performique, de l'acide formique, de l'eau oxygénée et un composé renfermant au moins un groupe ester et/ou un groupe (a) différent d'un groupe d'acide carboxylique, ainsi que l'utilisation de ces solutions.
