This invention relates to a process for the continuous manufacture of a salt solution, in particular for the manufacture of hexamethylenediamine adipate, and to an apparatus which can be operated by this process. According to the proposal of the present invention, the first step first converts less than the metered alkane diamine into alkane dicarbonate in water, and then the second step further adds the alkanediamine to carry out the reaction, wherein the relationship between the measurements is based on normal temperature. Depending on the pH measurement. |
