Diethylene glycol (DEG) is a clear, colourless, and odourless liquid with the chemical formula C4H10O3. DEG is similar in properties to MEG (mono ethylene glycol), but DEG has a higher boiling point, viscosity, and specific gravity. DEG is produced by the partial hydrolysis of ethylene oxide.
Diethylene glycol is a widely used solvent. It is used as a dehydrating agent for natural gas. Plus, it is used as a raw material for the production of plasticizers and polyester resins.
Characterization of Diethylene glycol (DEG)
Diethylene glycol is an organic compound which is soluble in water and many organic solvents. Some properties of this substance include:
- Its molar mass is 12 g. mol-1.
- Its melting point is -8 °C.
- Its boiling point is 245 °C.
- Its density is 1.12 gcm–3
Applications of Diethylene glycol (DEG)
Diethylene glycol has different applications in various industries. Some uses of Diethylene glycol include:
As a humectant
Diethylene glycol due to the hygroscopic properties, can be used in the tobacco industry to control the moisture of the tobacco filler. Plus, it is used in the treatment of paper, cork, and glue.
As a chemical intermediate
Diethylene glycol as a chemical intermediate, is used in the manufacture of unsaturated polyester resins, plasticizers, acrylate and methacrylate resins, and urethanes.
As a solvent
Diethylene glycol is used as a solvent for nitrocellulose, resins, dyes, oils, and other organic compounds.
As a constituent
Diethylene glycol is used as a constituent in the manufacture of hydraulic fluids. Plus, it is used for the production of esters used as emulsifiers, demulsifiers, and lubricants.
Diethylene glycol production
Diethylene Glycol (DEG) is a compound in which two molecules of Monoethylene Glycol (MEG) are dehydrated and condensed in ether form.
DEG is produced by the partial hydrolysis of ethylene oxide. The process involves the oxidation of ethylene at a high temperature in the presence of a silver oxide catalyst. The ethylene oxide is then hydrated to yield diethylene glycol along with monoethylene glycol and triethylene glycol as co-products.
Diethylene glycol storage
Diethylene glycol should be stored in stainless steel or aluminum drums. Recommended storage temperature for this product is 15 – 25 °C. DEG should be kept away from incompatible materials such as zinc. Some precautions for safe handling include:
- Wash hands with mild soap and water before eating, drinking, and when leaving work.
- Provide good ventilation in process area.
- Avoid breathing dust, fumes, and vapors.
Diethylene glycol health hazards
