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.
Application Area :
Water Treatment :
DEHA is used in Water Treatment Chemical Formulations for controlling corrosion in boiler very effectively due to its property of oxygen scavenging.It scoresover conventional hydrazine hydrate since it is far less toxic and meets the standard for disposal of blow offs without any difficulty giving a good protection against corrosion at the same time.
Polymerization:
DEHA's powerful free radical scavenging ability coupled with its moderate volatility and relatively low order of acute toxicity makes it an ideal "popcorn Polymer "/ vapour phase inhibitor for olefins or styrene monomer storage & recovery system.Because of its capability of inhibiting polymerization in the gas phase, DEHA is finding use as an in-process inhibitor for the production of styrene, divinylbenzene, butadiene, isoprene and other monomers containing a reactive double bond.
Photographic Chemicals:
DEHA has reducing property, so it is used as an auxiliary chemical photographic developer for instant colour photos. Also, DEHA is effective in stabilization of image and in the prevention of discolouration.
Decolourisation : Phenol and Phenolic antioxidants can be decolourised with DEHA.
Inhibitors: DEHA can be used as a colour stabiliser of monoalkyl phenol.
Silicon Rubber: DEHA can be used as a raw material for the hardener of the Silicon Sealant and coating agent.
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.
