DGA

DGA is essentially colorless, slightly viscous liquid with a mild amine odor. DGA is miscible with water, alcohols, and aromatic hydrocarbons, but relatively immiscible with aliphatic hydrocarbons and ethyl ether. Isometric with diethanolamine; however, the primary H2N group makes it more reactive. C4H11NO2 APPLICATIONS ? Used for carbonyl sulfide (COS) removal from liquid hydrocarbon streams ? Used as a selective solvent for recovery of aromatics from refinery streams ? Removes carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural and refinery gas, aliphatic hydrocarbon liquids and other sour hydrocarbon steams. ?Preparation of foam stabilizers, wetting and emulsifying agents, condensation polymers, photoresist strippers, and amides for personal care and metalworking applications.

Chemical-type goggles with face shield must be worn during handling or use of the undiluted product or concentrated solutions. Contact lenses should not be worn. Protective clothing, and gloves resistant to chemicals and petroleum distillates, must be worn. Should accidental eye contact occur, flush eyes with large amounts of water for at least 15 minutes. Eyelids should be held apart to permit rinsing of entire surface of eyes and lids. Get medical attention immediately. For skin contact, immediately flush skin with large amounts of water for at least 15 minutes. Get medical attention immediately. Contaminated clothing should be laundered before reuse.
