Description

AH Salt, formally known as hexamethylenediammonium adipate, is the ionic compound formed by the reaction of adipic acid (a dicarboxylic acid) and hexamethylenediamine (a diamine) with the chemical formula C6H16N2.C6H10O4. This salt is the essential intermediate for the production of polyamide 6,6 (PA 6,6, or nylon 6,6), a high-performance engineering polymer widely used in automotive, electrical, textile, and industrial applications.

AH Salt is typically prepared and handled as an aqueous solution. Both adipic acid and hexamethylenediamine are dissolved in water—often at elevated temperatures—to ensure complete reaction and dissolution. The resulting solution is usually concentrated to a specified solids content, often between 50% and 60% by weight, and is colorless and viscous at room temperature.
