The present invention relates to a process for the preparation of a solution comprising a first peroxy acid comprising performic acid and a second peroxy acid, said process comprising forming a carboxylic acid solution comprising a first carboxylic acid comprising formic acid, a second carboxylic acid and hydrogen peroxide, wherein the amount of formic acid is from 0.5 to 20 % by weight of the amount of the second carboxylic acid, and allowing the components to react to form a solution comprising performic acid and said second peroxy acid, the amount of peroxy acids being at least 5 % by weight. The invention also relates to a storable solution comprising performic acid and said second peroxy acid. The solution can be used as a disinfecting agent for controlling micro-organisms.
L'invention concerne un procédé de préparation d'une solution contenant un premier peroxyacide contenant de l'acide performique et un second peroxyacide. Ce procédé consiste à former une solution d'acide carboxylique contenant un premier acide carboxylique contenant de l'acide formique, un second acide carboxylique et du peroxyde d'hydrogène, la quantité d'acide formique est comprise entre 0,5 et 20 % en poids de la quantité du second acide carboxylique. Ce procédé consiste ensuite à laisser réagir les composants de façon à obtenir une solution contenant de l'acide performique et le second peroxyacide, la quantité de peroxyacides étant d'au moins 5 % en poids. L'invention concerne également une solution stockable contenant de l'acide performique et le second peroxyacide. Cette solution peut être utilisée comme un désinfectant afin de lutter contre les micro-organismes.
