Diethyl Hydroxyl Amine N,N- DEHA
N,N-DIETHYLHYDROXYLAMINE DEHA, N-Ethyl-N-Hydroxy-Ethanamine
A colourless to pale yellow transparent liquid, available as 98% DEHA and also as 85% solution in water. Di Ethyl Hydroxyl Amine (DEHA) is versatile products use for Controlling the corrosion inhibitor, Photographic etc.
It is use for Water Treatment Chemical, Corrosion Inhibitor, Polymerization, Photographic Chemicals, Decolourisation, etc.
DEHA used as a volatile oxygen scavenger and reacts in a ratio of 2.8/1 DEHA/O2.
Application Area of DEHA :
Water Treatment , Polymerization, Photographic Chemicals, Decolourisation , Inhibitors, Silicon Rubber
Storage :
Can be stored and handled in equipment made of stainless steel of Type SS304 or SS316 or steel lined with glass, polypropylene or polyethylene. Storage in mild steel equipment or containers is not recommended. DEHA drums should be stored in a cool and well ventillated area, away from sources of ignition.
Packing :
25 Ltrs, 210 Ltrs. in new UN approved HMHDPE drums / In ISO Tanks of 20 Mt's capacity.
Health & Safety :
DEHA is irritating to skin,eyes and the mucous membrane. In case of contact,affected area to be washed with plenty of water for atleast 15 minutes. In case of inhalation,victim should be moved to fresh air and oxygen should be administered. In case of ingestion,victim should be made to consume copious quantity of milk and water. Medical advice should be sought at once. Personal protective equipment should always be used while handling.

Diethylhydroxylamine (DEHA) is an organic compound with the formula (C2H5)2NOH. 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. Due to its volatility, it acts as an oxygen scavenger throughout the entire boiler system due to steam carryover. DEHA also reacts with ferrous metals to form a passivized film of magnetite throughout the boiler system.
