Abstract:
Processes are disclosed for preparing a diamine/dicarboxylic acid salt, wherein the dicarboxylic acid includes an aromatic dicarboxylic acid and is provided in a powder form. The diamine is provided in a liquid form gradually dosed to the dicarboxylic acid powder, while keeping the dicarboxylic acid powder in constant movement; the processing temperature is above 0° C. and below the boiling temperature of the diamine and the melting temperature of the acid and the salt, and the reaction mixture comprises at most 5 wt. % of water. An anhydrous diamine/dicarboxylic acid salts obtained by the process are also provided.

Claim (Index 1):
A process for preparing a diamine/dicarboxylic acid salt comprising the steps of:\n (i) forming a reaction mixture by contacting a diamine liquid with a dicarboxylic acid powder comprising an aromatic dicarboxylic acid; and (ii) allowing the diamine and the aromatic dicarboxylic acid in the reaction mixture to react to form a diamine/dicarboxylic acid salt, wherein step (i) comprises the steps of: (a) gradually dosing the diamine liquid to the aromatic dicarboxylic acid powder, while keeping the aromatic dicarboxylic acid powder in constant movement, and thereafter (b) keeping the reaction mixture in constant movement for a time period directly following completion of the dosing; wherein steps of (a) and (b) are carried out at a temperature above 0\u00b0 C. and below all of the following: the boiling temperature of the diamine and the melting temperatures of the dicarboxylic acid, the diamine/dicarboxylic acid salt and any intermediate reaction product, and wherein the reaction mixture in steps (a) and (b) comprises at most 5 wt. % of water, relative to the total weight of the diamine and dicarboxylic acid; and wherein the diamine consists of a mixture of different diamines.
