Diethylene glycol (DEG) is an odorless and colorless organic compound with the chemical formula C4H10O3 and soluble in water and many organic compounds. This combination is used in many chemical industries due to its proper dehumidification ability. This compound is widely used as a reactive solvent in the production of plastic and other products. DEG is miscible in water, alcohol, ether, acetone and ethylene glycol, and of course it is widely used as a solvent. This product is relatively viscous and colorless liquid that has a mild smell. Due to the lower toxicity of triethylene glycol compared to diethylene glycol, this substance has been replaced by diethylene glycol in some industries and uses. \r\n Diethylene glycol is very similar to monoethylene glycol in terms of properties and characteristics, but diethylene glycol has a higher boiling point, viscosity and density. MEG is the raw material for the production of polyester fibers, PET resins, alkyds and unsaturated polyesters, but diethylene glycol is used in the production of unsaturated polyester resins, polyurethanes and plasticizers.
