It is a colorless, practically odorless, poisonous, and hygroscopic liquid with a sweetish taste. It is miscible in water, alcohol, ether, acetone, and ethylene glycol.[1] DEG is a widely used solvent. It can be a contaminant in consumer products; this has resulted in numerous epidemics of poisoning since the early 20th century.Diethylene glycol is used in the manufacture of unsaturated polyester resins, polyurethanes, and plasticizers.[1] DEG is used as a building block in organic synthesis, e.g. of morpholine and 1,4-dioxane. It is a solvent for nitrocellulose, resins, dyes, oils, and other organic compounds. It is a humectant for tobacco, cork, printing ink, and glue.[5] It is also a component in brake fluid, lubricants, wallpaper strippers, artificial fog solutions, and heating/cooking fuel.[1] In personal care products (e.g. skin cream and lotions, deodorants), DEG is often replaced by selected diethylene glycol ethers. A dilute solution of diethylene glycol can also be used as a coolant; however, ethylene glycol is much more commonly used. Most ethylene glycol antifreeze contains a few percent diethylene glycol, present as an inadvertent byproduct of ethylene glycol production. Diethylene glycol (DEG) is a valuable chemical intermediate used in the production of unsaturated polyester resins (UPR), plasticizers, acrylate and methacrylate resins and urethanes. Applications for Diethylene Glycol: Polyester Resins Antifreeze and Coolants Gas Dehydration and Treating Chemical Intermediates Heat Transfer Fluids Solvents Other Applications Polyester Resins Ethylene glycols are used as a reactant in the manufacture of polyester resins. Dow produces ethylene glycols for use in polyester fiber, films and polyethylene terephthalate (PET) resin production, as well as alkyd resins used in paints. The uses for polyester resins are extremely varied, and include boat and marine, construction materials, automotive and aircraft bodies, luggage, furnishings, appliances, textiles and packaging.Polyester fibers are commonly found in textile applications including clothing and carpets.Polyester films are frequently used in packaging and wraps for consumer goods, as well as video, audio and computer tapes. PET is widely used in the manufacturing of beverage bottles and containers, and other consumer goods packaging. Antifreeze and Coolants Ethylene glycols remain viscous at low temperatures; they have a low freezing point and high boiling point. Ethylene glycols are frequently used to make automobile antifreeze and coolants, aircraft anti-icing and deicing materials. Gas Dehydration & Treating Ethylene glycols are commonly used in natural gas hydration and treating applications to remove water and impurities. Diethylene glycol (DEG), Triethylene glycol (TEG) and Tetraethylene glycol (TETRA EG) have excellent hygroscopicity and low volatility. Because of these characteristics, DEG, TEG and TETRA EG are in high demand in the natural gas drying market. Chemical Intermediates Ethylene glycols including monoethylene glycol (MEG), diethylene glycol (DEG), triethylene glycol (TEG) and tetraethylene glycol (TETRA EG), are versatile chemical intermediates used to produce a variety of products for commercial and industrial use: Adhesives and coatings Emulsifiers Lubricants Plasticizers Polyurethane foams Solvents Silicone compounds Thermoplastics Unsaturated polyester resins Heat Transfer Fluids Monoethylene glycol (MEG), diethleyene glycol (DEG), triethylene glycol (TEG) and tetraethylene glycol (TETRA EG), due to their low freezing point, freezing point depressant and high boiling point are predominantly used in heat transfer fluids. Solvents Diethylene glycol (DEG), triethylene glycol (TEG) and tetraethylene glycol (TETRA EG) have excellent solvent properties. TEG and TETRA EG are used as solvents in several applications: Aromatic and paraffinic hydrocarbons separations Cleaning compounds Cyanoacrylate and polyacrylonitrile Polyethylene terephthalate (PET) production equipment cleaning Steam-set printing inks Other Applications Triethylene glycol (TEG) and tetraethylene glycol (TETRA EG) may be used directly as a plasticizer or modified by esterification. As a plasticizer, TEG and TETRA EG are used in the manufacture of: Safety glass Separation membranes (silicone rubber, polyvinyl acetate, cellulose triacetate) Ceramic materials (resistant refractory plastics, molded ceramics) Demand for tetraethylene glycol is strong in the area of BTX (benzene, toluene, xylene) extraction to separate aromatic hydrocarbons from non-aromatic hydrocarbons. Monoethylene glycol (MEG), diethylene glycol (DEG) are often used in water-based paints, dry-wall compounds, glass cleaners, dyes, waxes and adhesives as a freezing point depressor to avoid damage by low-temperature extremes. In addition, monethylene glycol and diethylene glycol are also used as binders for foundry sand molding, and a lubricant for glass- and cement-grinding. In addition, both homologs are also used as humectants in textile fiber, paper, leather, adhesive and glue applications.
