ABSTRACT:
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. The process results in less solid formation than commonly used alkali metal bases such as aqueous sodium hydroxide or aqueous potassium carbonate.
