Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Photodegradation in air

In the atmosphere a half-life of 2.9 days for adipic acid is estimated due to indirect photolysis with hydroxyl radicals, considering an OH-concentration of 500,000 radicals/cm³ as a 24-h average.


Hydrolysis of adipic acid is not expected, as the substance does not contain hydrolysable functional groups.

Photodegradation in water

A liquid phase kinetic study on the ozonolysis and on the UV-induced ozonolysis of selected dicarboxylic acids, including adipic acid was performed, resulting in an ozone-dependent life time of about 13,000 years.
