- Model NO.: CAS NO. 929-06-6
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.
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.
