Information about diethylene glycol

Production of diethylene glycol

This substance is produced from ethylene by an intermediate called ethylene oxide. In this process, EO and water react together and ethylene glycols including MEG, DEG and TEG (triethylene glycol) are produced. One of the interesting points about this reaction is that the reaction can be performed in environments with different pH, but to achieve higher efficiencies, it is recommended to perform the reaction in an acidic or neutral environment with excessive amounts of water.

Application of diethylene glycol

Diethylene glycol as a solvent in the oil and gas industry. Diethylene glycol for dehydration of natural gases and other gases. This material is widely used in hydrating natural gas and making it usable by removing impurities and absorbing water.
Application of this organic compound as an intermediate in the production of unsaturated polyester resins, polyurethane foam, emollients
As a solvent, for dehydration and dehumidification of natural gases and other gases due to special properties such as dehumidification, resistance to heat and chemical decomposition, low vapor pressure and reasonable price of diethylene glycol As a dehumidifier, it is known as a natural gas dehumidifier due to its water absorption properties, excellent heat and chemical decomposition, low vapor pressure and reasonable price. Can be replaced with some diethyl glycol esters It is used as a stabilizer in mixtures of soluble oils, a coupling agent and an adapter for inks and paints, chemical intermediates in emulsifiers, lubricants and morpholines. Solvents of materials such as nitrocellulose, resins, dyes, oils and other organic compounds TEG production
Production of personal care products including creams, lotions and solvent deodorants
It can act as a reactant in the manufacture of polyester resins
These polyester resins have a variety of uses in everyday consumables. These include applications in furniture, luggage, car and aircraft fuselages, fabrics, beverage bottles, and more.
DEG-produced polyester fibers are widely used in the textile industry, including textiles and carpets.
They are also antifreeze. This material can remain at low viscous temperatures. DEG can be used as an antifreeze and coolant in cars due to its low freezing point and high boiling point. Of course, in industry, EG is mostly used as antifreeze and cooling, not its derivatives. They are also used in the heat transfer of liquids because of this important property in DEG
