Diethylene glycol:

Diethylene glycol is abbreviated. This is an organic compound. Its appearance is a colorless liquid, which is practically odorless, toxic and moisturizing with a sweet taste. It can be mixed in water, alcohol, ether, acetone and ethylene glycol. Diethylene glycol is a widely used solvent that can be contaminated in consumer products. Diethylene glycol is a type of glycol and a subset of chemicals. A viscous, colorless, colorless, dehumidifying hydroscopic liquid commonly used in the commercial manufacture of antifreeze, brake fluid, cigarettes, and some paints. It is an excellent solvent for many relatively insoluble materials. Diethylene glycol is also commonly used in human drugs such as acetaminophen and sulfanilamide.

Diethylene glycol production:

Diethylene glycol is produced by partial hydrolysis of ethylene oxide. Depending on the conditions, different amounts of DEG and related glycols are produced. The product is two molecules of ethylene glycol, which are joined together by an ether bond. Diethylene glycol is obtained as a joint product with monoethylene glycol (MEG) and triethylene glycol. The industry generally works to maximize MEG production. Ethylene glycol is by far the largest volume of glycol products in various applications

Diethylene glycol is one of the most commonly used organic solvents, covering a wide range of industrial applications. This compound can dissolve many organic solvents. Chemical properties and special applications (DEG) have been of interest to scientists since the 20th century.

Diethylene glycol is produced during a series of hydrolysis reactions in several steps. In these reactions, ethylene oxide is the raw material and diethylene glycol is produced as a final product along with a mixture of other glycols. Compounds such as ethylene diglycol, monoethylene glycol and triethylene glycol are produced in these reactions.


 Diethylene glycol applications:

  • Diethylene glycol is used in the manufacture of saturated and unsaturated polyester resins.
  • Used to produce a variety of polyurethanes and emollients.
  • Approved as a constituent element in organic synthesis. For example: to produce morpholine and dioxane.
  • This solvent is used to produce nitrocellulose, resins, dyes, oils and other organic compounds.
  • Also used as emollient, antifreeze, liquid fuel.
  • Used as a moisturizer for tobacco, cork, printing ink and glue.
  • Used in the production of brake fluid.
  • Used to make wallpaper strippers.
  • In the manufacture and production of solutions of fog and artificial fog.
  • In personal care products (eg skin creams and lotions, deodorants), diethylene glycol is often replaced by diethylene glycol ethers.
  • A dilute solution of diethylene glycol can be used as a cryoprotectant.
  • Most ethylene glycol antifreezes contain a few percent of diethylene glycol, which is present as a by-product in the production of ethylene glycol.

The role of diethylene glycol in the environment:

Diethylene glycol has been identified in drinking water, groundwater, surface water and indoor air due to its release to the environment from its production and use. When diethylene glycol is released into the soil or water, it is highly mobile. Absorption into soil and sediment is very low. Escape is not expected to be important. On the soil surface it is not sensitive to photolysis, but is expected to degrade rapidly in soil and water. The bioaccumulation of diethylene glycol in aquatic organisms is expected to be low due to the estimated concentration coefficient of 0.05.

When diethylene glycol is released into the atmosphere, the vapor phase is destroyed by the reaction of photochemically produced hydroxyl radicals with a half-life of 13 hours. Diethylene glycol in the air in the particle phase may be destroyed by wet precipitation.

diethylene glycol producers:

The raw material of diethylene glycol is produced in Shazand, Morvarid, Farsashimi and Maroon petrochemicals.
