Diethylhydroxylamine (DEHA) is an organic compound with the formula (C 2 H 5) 2 NOH. It is a colorless liquid, although it is usually encountered as a solution. It is mainly used as an oxygen scavenger in water treatment. It is a volatile oxygen scavenger and reacts in a ratio of 2.8/1 DEHA/O2. It is employed in high pressure (>70 bar) boiler systems due to a very low rate of reaction at low temperatures and pressures.
