Additional information

AH-salt is a salt which does not sublime. Therefore, degradation of AH-salt by photolytic mechanisms in the atmosphere is not expected to be of relevance. For the two components of AH-salt: Adipic acid, CAS-No 124-04-9 and 1,6-Hexametylenediamine, CAS-No 124-09 -4, the estimated half lifes for photodegradation are t1/2 = 69 hours and 5,6 hours, respectively.
