Title:

低水分ジアミン/ジカルボン酸塩の製造

Document Type and Number:

Japanese Patent JP3939764

Kind Code:

B2

Abstract:

The invention provides a process for directly manufacturing a diamine/dicarboxylic acid salt with a low water content. The process includes reacting a diamine with a dicarboxylic acid to form a diamine/dicarboxylic acid salt. The reaction of the diamine and the dicarboxylic acid is carried out in the presence of about 0.5% to about 25% by weight water, based on the weight of the reaction mixture, while providing conditions in the reaction mixture such that the reaction mixture is in substantially solid particulate form.
