Hexamethylene diamine adipate is the reaction product of adipic acid and hexamethylene diamine and is an intermediate in the manufacture of nylon 6,6. The common name AH salt is derived from the initial letters of the starting substances.

The AH salt method for the production of polyamide 6.6 is a reaction of the salt under pressure (approx. 15 bar) and temperature (approx. 250 ° C) by splitting off water.

Since the end of 2012, the BASF company in Ludwigshafen am Rhein has had a plant with an annual capacity of 24,000 t of AH salt per year. Hexamethylenediamine adipate is one of the chemical substances that are produced in large quantities (" High Production Volume Chemical ", HPVC) and for which the Organization for Economic Cooperation and Development (OECD) collects data on possible dangers (" Screening Information Dataset ", SIDS).
