Abstract[English]
A method to increase the stability of an aqueous composition comprising an alkanolamine, said method comprising the steps of: - providing a vessel; - adding a pre-determined amount of water into said vessel; - adding a pre-determined amount of an acid to said water; and - adding said alkanolamine to said vessel; and - mixing the blend until resulting mixture is homogeneous; wherein the resulting mixture of alkanolamine and said acid has a pH ranging from 7 to 11, is stable down to a temperature of -5°C and said resulting mixture comprises said alkanolamine and HCl in a molar ratio ranging from 1:1 to 1:0.1 of alkanolamine:acid.[French]
L'invention concerne un procédé permettant d'augmenter la stabilité d'une composition aqueuse comprenant une alcanolamine, ledit procédé comprenant les étapes consistant à : mettre à disposition un récipient ; ajouter une quantité prédéfinie d'eau dans ledit récipient ; ajouter une quantité prédéfinie d'un acide à ladite eau ; et ajouter ladite alcanolamine audit récipient ; et mélanger le mélange jusqu'à ce que le mélange résultant soit homogène ; le mélange résultant d'alcanolamine et dudit acide ayant un pH allant de 7 à 11, étant stable jusqu'à une température de -5 °C et ledit mélange résultant comprenant ladite alcanolamine et HCl dans un rapport molaire allant de 1 : 1 à 1 : 0,1 d'alcanolamine : acide.
