(GLP compliant study based on the OECD Guideline 112, 1981)
Author: Dr. Ir. E. Baltussen

Key value for chemical safety assessment

pKa at 20°C:
3.25

Additional information

The Dissociation constant of the isomer p-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline was determined based on the procedures indicated by the internationally accepted method from the OECD Guideline 112.

The pKa value was determined for p-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline using the spectrophotometric method. This pKa value determined for p-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline is 3.25 and corresponds to the dissociation of a basic group in the molecule. It is considered that the pKa value of

m-(2,3-epoxypropoxy)-N,N-bis(2,3-epoxypropyl)aniline is similar
