Product Information

DIGLYCOLAMINE® Agent (DGA®) is an essentially colorless, slightly viscous liquid. The product is a non-volatile primary amine with a low tendency to leach cobalt, aluminum, or copper. It is 2-(2-Aminoethoxy)Ethanol.

DGA® is a versatile amine used across a range of applications. It is used in gas treating as an amine solvent for the bulk removal of hydrogen sulfide, carbon dioxide and carbonyl sulfide. Other major applications include electronics and metalworking, and it is an intermediate for products in end-use applications ranging from agrochemicals to polyurethane foam insulation.

Features of DIGLYCOLAMINE® Agent (DGA®)

• Primary Amine
• Isomeric with DEA
• Inventory listed (TSCA, EINECS, MITI, DSL, AICS)
• Used commercially in U.S. and Europe as DEA replacement
• Low toxicity profile
• Non-mutagenic
• Non-dermal sensitizer
• Lower volatility, higher boiling and flash points than other DEA substitutes
• Lower freezing points than other DEA substitutes
• Provides buffering and corrosion protection
• Lime-tolerant
• Readily forms amides

Benefits of DGA®

• DEA free
• Reacts readily with acids to form amides and salts
• Stoichiometrically equivalent to DEA
• Minimal disposal problems
• Reduced volatility and respiratory concerns; Good cold weather handling
• Similar to DEA in providing buffering capacity
• Amides provide lubricity, emulsification, hard water stability

Applications of DIGLYCOLAMINE® Agent

• 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.
