Diethylene Glycol (DEG)
Diethylene glycol (also known as DEG, 2,2-oxydiethanol and diglycol) is a clear, colourless, odourless liquid with the formula C4H10O3. It is soluble both in water and in many organic compounds and has hygroscopic properties which makes it a useful industrial chemical.
Diethylene glycol is similar in properties to MEG (mono ethylene glycol), but DEG has a higher boiling point, viscosity, and specific gravity. MEG is the raw material used in the production of polyester fiber, PET resins, alkyds, and unsaturated polyesters. Diethylene glycol is used in the manufacture of unsaturated polyester resins, polyurethanes and plasticizers. It is a water-soluble liquid; boiling point 245 C, and is soluble in many organic solvents.
Properties Of DEG

Benefits of DEG
- Antifreeze solutions, solvents, paints, polyester resin, lubricants, brake fluid, adhesives
- In Japan, it is mostly utilised as a cement grinding aid. It can also be used in petroleum solvent extraction and can be found in printing ink and drywall joint compounds.
- The compound is also used as a chemical intermediate in the manufacture of unsaturated polyester resins, plasticisers, acrylate and methacrylate resins, and urethanes.
