A radiation-induced chain decomposition of aqueous triethanolamine into acetaldehyde and diethanolamine is reported.Chain length over 1000 have been observed, depending on pH, concentration, and radiation intensity.The chain propagation steps include OH group migration in the 2-hydroxy-1-(diethanolamino)ethyl radical and NR2 migration in 1-hydroxy-2-(diethanolamine)ethyl radical, each producing a 2-hydroxy-2-(diethanolamine)ethyl radical.Free-radical spectra and rate constants are given.Studies of diethanolamine and diethylethanolamine solutions gave similar free-radical spectra but much shorter chains.
