Nanosecond pulse radiolysis of aqueous N, N-diethylhydroxylamine solution

The reaction mechanisms and rate constants of N, N-diethylhydroxylamine (DEHA) with · OH, CO 3 − · , e aq − and · H were studied. Results show that · OH radicals oxidize DEHA by hydrogen abstraction from DEHA’s hydroxyl group to form transient (C 2 H 5 ) 2 NO · , which has an absorption maximum at 395 nm. The transient intermediates for the reactions of DEHA with CO 3 − · and e aq − , as well as protonated DEHA with · H, show no absorption peak between 300 and 800 nm. The rate constants for the reactions of DEHA with · OH, CO 3 − · and e aq − , also protonated DEHA with · H, were measured.
