    摘要: The invention relates to a method for the continuous production of a solution of salts, in particular for the production of hexamethylenediamine adipate and a device for implementing such a method. According to the invention, it is proposed to convert, in a first step, a substoichiometric quantity of alkane diamine in a ratio to the alkane dicarboxylic acid in water and, in a subsequent second step, to implement making-up with alkane diamine, adjustment of the stoichiometric ratios being effected via a pH value measurement at a constant temperature.
