Diethylene Glycol (DEG)

Diethylene glycol is a chemical compound with the formula C2H6O2. This colorless, odorless, and viscous liquid has a sweet taste. Primarily used as a solvent, it is also employed as a raw material for polyester production and as an effective agent in antifreeze, coolants, and other products. DEG is derived from ethylene, wherein ethylene is converted to ethylene oxide. This material possesses advantages such as high solubility in water and organic solvents, low freezing point, and low toxicity. However, it also has disadvantages including flammability, corrosiveness, and environmental impact.

Analysis of Diethylene Glycol from Marun Petrochemical Company

This material is referred to as a byproduct of the manufacturing of monoethylene glycol (MEG). Ethylene is oxidized at high temperatures with a silver oxide catalyst present to create this material. During this process, ethylene oxide is hydrated, producing diethylene glycol along with MEG and triethylene glycol as co-products. The result of this process is that diethylene glycol is produced less compared to MEG.

Diethylene glycol, on the other hand, is a highly practical chemical used in the chemical industry. In this procedure, the chemical companies aim to maximize the production of MEG.

Export Statistics:

Diethylene glycol is a chemical used in the production of polyester, antifreeze, and cosmetic and personal care products. In 1400 (2021-2022), Iran exported more than 200,000 tons of this chemical material worth over 100 million dollars to various countries. Iran’s DEG exports were primarily destined for China, India, Turkey, Pakistan, and Iraq. The global price of this chemical in various markets is what determines the price of DEG exported from Iran.

Diethylene glycol is one of the most well-known solvents in the industry. It is crucial for the production of many products, such as saturated and unsaturated polyester resins and antifreeze.

Despite its many uses, this product is primarily known as a solvent because of its high capacity to absorb moisture, which is important for products that are sensitive to moisture. Furthermore, because of its appropriate boiling and freezing points, DEG contributes to the manufacture of a product that is widely used, antifreeze, and it dissolves in solvents like alcohols, ethers, and ketones. Despite the numerous industrial applications introduced for this product, its primary function as a solvent comes from its remarkable solvency properties.

Ethylene oxide is used as the main raw material in the production of this material, which is then created via hydrolysis and several further processes. These reactions also produce a mixture of additional glycols in addition to Diethylene glycol. Under appropriate environmental conditions, diethylene glycol exists as a colorless and transparent liquid. Another sensitive characteristic of this product is its high flammability.

Applications of Diethylene Glycol (DEG):

– used to clean equipment, such as that used in the manufacturing of polyethylene terephthalate (PET), and to separate aromatics and paraffinic hydrocarbons.

– works as a freezing agent

– serve as a reactant in the manufacturing process of polyester resins, which are used to make upholstery, bags, automobile and airplane bodies, fabrics, drink bottles, and other items.

– by eliminating contaminants and absorbing water, it is utilized to dehydrate natural gas and other gasses, and it plays a vital part in the process of dehydrating and using natural gas.

– It acts as a solvent in natural and other gases to remove water and absorb moisture.

– It has been recognized for being a superior natural gas moisture absorbent.

– Employed as an intermediary ingredient in emulsifiers, lubricants, and morpholine; stabilizer in oil mixes; coupling agent and compatibilizer for inks and dyes.

Buyers of this product can be assured of the properties and reasonable price of the purchased this material.

This material should be kept under Nitrogen blanket and ambient temperature.


Points to consider when storing DEG:

  • It should be stored in a dry, cool place, away from direct sunlight.
  • Store it in tightly sealed containers to prevent evaporation and degradation.
  • Avoid contact of this material with calcium, humic compounds, and acids.
  • Keep it out of reach of pets and children, as ingestion can be toxic.
  • Store at temperatures below 40 degrees Celsius, as higher temperatures may cause it to lose its properties or convert to ammonia.

DEG packaging for export can be Bulk, IBC, Plastic Drummed.
