1. Product Introduction & Main Application
Arnico’s Diethylene Glycol (DEG) is a clear, colorless, viscous, and sweet-tasting liquid used as a high-boiling point industrial solvent and humectant in petrochemical, gas processing, and resin production. This substance plays a critical role in the dehydration of natural gas and is a vital component in various chemical processes.

3. Features & Benefits
-
Ideal Boiling Point & Vapor Pressure: High thermal stability allows for use in natural gas absorption and distillation columns without solvent loss.
-
Exceptional Hygroscopic Power: Rapidly and effectively absorbs water from sour gas streams, preventing the formation of ice-like hydrates in pipelines.
-
Purity & Chemical Stability: Resistant to degradation and oxidation over long thermal cycles, reducing glycol replacement costs.
-
Effective Solvent: High dissolving power for industrial resins and dyes with a controlled evaporation rate.
4. Industrial Applications
-
Oil & Gas Industry: The primary process material for natural gas dehydration (Glycol Dehydration Units) in refineries and offshore platforms.
-
Antifreeze & Heat Transfer Fluids: Formulation of industrial antifreeze and compressor cooling fluids.
-
Resin & Polymer Industry: A raw material in the production of unsaturated polyester resins and polyurethane plasticizers.
-
Chemical Industry: A co-solvent in the production of paints, printing inks, and hydraulic fluids.
5. Safety & Handling
-
MSDS (Material Safety Data Sheet): This substance is toxic if ingested and can cause kidney damage (unlike MPG, which is safe). Skin and eye contact is irritating. A thorough study of the Arnico MSDS is mandatory before use.
-
Storage Conditions: Store in sealed carbon steel or stainless steel tanks, in a dry, cool place, and away from strong oxidizing agents and heat sources. Due to its hygroscopic nature, tanks must always be kept airtight.
-
Personal Protective Equipment (PPE): When decanting and handling, the use of chemical-resistant gloves and safety goggles is mandatory. In case of splashing or ingestion, seek medical attention immediately.
6. Quality Assurance & COA
All Arnico Diethylene Glycol shipments are accompanied by a complete COA, including a precise GC analysis of purity and the content of Ethylene and Triethylene Glycol impurities.
