Diglycolamine® Agent (DGA® Agent)

• Huntsman is one of the largest global producers of specialty amines, with an annual capacity exceeding 90 million pounds. The DIGLYCOLAMINE® Agent (DGA®) can be reacted with fatty acids to form amides and amine salts for foam-boosting surfactants, stabilizers, detergents, and LAS emulsifying and wetting agents in shampoos, metalworking, paper treating and textile operations.
• The DIGLYCOLAMINE® (DGA®) brand of 2-(2- aminoethoxy) ethanol is a critical component in the removal of hydrogen sulfide and/or carbon dioxide from gas streams. In addition to supplying this market, Huntsman is a leader in supplying this proven technology in increasing quantities for paint strippers, photoresist strippers for electronic circuit boards, specialty surfactants, corrosion inhibitors, cutting fluids, amides, and other applications where primary amines are useful.
• Physically, DIGLYCOLAMINE® Agent is a clear, viscous liquid at room temperature and a white crystalline solid below its freezing point of 9.5°F (-12.5°C). DIGLYCOLAMINE® Agent has a relatively high boiling point and low vapor pressure.
• It is hygroscopic and miscible with water, most alcohols, and most polyols. Aqueous solutions of DIGLYCOLAMINE® Agent are alkaline. Being bifunctional, DIGLYCOLAMINE agent reacts with acids to form esters or salts. Most areas of use for DIGLYCOLAMINE® Agent are dependent to some degree on these features.
• The use of DIGLYCOLAMINE® Agent solution for gas treatment purposes holds great promise, both in new plants and in the conversion of existing amine facilities to obtain either lower treatment costs or an inexpensive means of debottlenecking existing treating facilities.

• DIGLYCOLAMINE® AGENT is used for carbonyl sulfide (COS) removal from liquid hydrocarbon streams.
• DIGLYCOLAMINE® AGENT is 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 streams.
• DIGLYCOLAMINE® AGENT is used in preparation of foam stabilizers, wetting and emulsifying agents, condensation polymers, photoresist strippers, and amides for personal care and metalworking applications.

• Delivery of DIGLYCOLAMINE® Agent can be made in 10,000 and 20,000-gallon tank cars. These cars are constructed of welded carbon steel and have bottom unloading fittings and steam coils.
• Deliveries can also be made in insulated, stainless steel, full or compartmented tank wagons with steam coils. If requested, tank wagons can be equipped with unloading pumps and hoses.
• Drums of DIGLYCOLAMINE® Agent can be shipped in truckload or less-than-truckload quantities. The net weight of a drum is 480 pounds; the gross weight is approximately 501 pounds per drum. Drums are UN1A1 or UN1H1, nonreturnable.
• Under U.S. Department of Transportation (DOT) and Canadian Transportation of Dangerous Goods (TDG) regulations, the proper shipping name for DIGLYCOLAMINE® Agent is “2-(2-aminoethoxy)ethanol,” identification number UN 3055. This product is considered a corrosive material (TDG hazard class 8) and requires a “CORROSIVE” label for shipping.

DGA® Agent is available in bulk, and in drums of 480 pounds (218 kilograms) net weight.

The product should retain its conformance to sales specifications for a period of at least two years after shipment if the product is stored at less than 100°F in its undamaged, unopened, factory packaged container. In general, the user should determine the suitability of any chemical compound, no matter what the shelf life or length of time of storage. Each user should conduct a sufficient investigation to establish the suitability of any product for his intended use.
