| titleOfInvention | Method for producing diacid / diamine salt solution |
| abstract | The present invention relates to a process for producing a solution of a salt of diacid and diamine for the production of polyamide. More particularly, the present invention relates to an aqueous solution of a diacid and diamine salt obtained by mixing at least two diacids and at least one diamine at a salt concentration in the range of 40-70%. A process for preparing (A), wherein an aqueous solution of diacid and diamine is produced in the first step starting from the diacid and diamine and showing a diacid / diamine molar ratio of less than 1 and in the second step The salt concentration by weight is adjusted by adjusting the acid / diamine molar ratio to a value in the range of 0.9 to 1.1 and adding another diacid and optional make-up water and / or make-up diamine. It relates to said method comprising fixing. |
