CA 2278455

A process is disclosed for the neutralization of amine or alkanolamine heat stable salts with aqueous KOH or with alkali metal base, such as potassium hydroxide, sodium hydroxide, sodium carbonate, potassium carbonate, sodium bicarbonate or potassium bicarbonate, formulated with amines or alkanolamines, resulting in less solids formation than commonly formed when alkali metal bases, such as aqueous sodium hydroxide or aqueous potassium carbonate.

L'invention a trait à un procédé permettant de neutraliser des sels d'amine ou d'alcanolamine thermostables à l'aide d'hydroxyde de potassium aqueux ou d'une base de métal alcalin, par exemple de l'hydroxyde de potassium, de l'hydroxyde de sodium, du carbonate de sodium, du carbonate de potassium, du bicarbonate de sodium ou du bicarbonate de potassium, en formulation avec des amines ou des alcanolamines, ce qui réduit la formation de matières solides en comparaison de ce qu'il en est lorsque l'on utilise des bases de métal alcalin telles que de l'hydroxyde de sodium aqueux ou du carbonate de potassium aqueux.
