Patent

CA 2166480

Sodium perborate is mixed with a mixture, preferably a 1:1 mixture, of a rapid acetylating agent, e.g. TAED, and a slow acetylating agent, e.g. acetylsalicylic acid, in water to form a biocidally effective peracetic acid solution. When sodium perborate and TAED alone react in water, peracetic acid is produced quickly but has relatively little stability and a short useful life (curve 10). When sodium perborate and acetylsalicylic acid are mixed in water, the peracetic acid solution takes an extended duration to reach maximum efficacy, but is stable for an extended duration (curve 12). The mixture of rapid and slow acetylating agents quickly produces a stable peracetic acid concentration (curve 14).

On introduit dans l'eau du perborate de sodium et un mélange, de préférence dans un rapport de 1:1, d'un agent d'acétylation rapide tel que le TAED et d'un agent d'acétylation lente tel que l'acide acétylsalicylique. On obtient ainsi une solution biocide efficace d'acide peracétique. Lorsque le perborate de sodium réagit avec le seul TAED dans l'eau, l'acide peracétique est produit rapidement mais il est relativement peu stable et la durée de vie du composé actif est courte (courbe 10). Quand le perborate de sodium et l'acide acétylsalicylique sont mélangés dans de l'eau, la solution d'acide peracétique nécessite un certain temps pour atteindre son efficacité maximale mais elle reste stable pendant plus longtemps (courbe 12). Le mélange d'agents d'acétylation rapide et lente fournit rapidement une concentration stable d'acide paracétique (courbe 14).
