METHOD FOR PRODUCING AN AQUEOUS SOLUTION OF SALTS |
摘要 |
The invention relates to a method for continuously producing a solution of salts, in particular for producing hexamethylenediamine adipate, and to a device for carrying out such a method. According to the invention, in a first step a substoichiometric quantity of alkane diamine in relation to the alkane dicarboxylic acid is reacted in water, and in a subsequent second step an additional metered amount of alkane diamine is added, wherein the stoichiometric relationships are adjusted by means of a pH value measurement at a constant temperature. |
