Key value for chemical safety assessment

Additional information

Ethanol, 2,2'-oxybis-, reaction products with ammonia, morpholine derivs. residues is a mixture of substances with a large number of different amine groups. For each of these groups a discret dissociation constant can be defined, but not determined by titration. The determination of the dissociation constant of an aqueous preparation of Ethanol, 2,2'-oxybis-, reaction products with ammonia, morpholine derivs. residues according to OECD Guideline 112 was not feasible.
