Definition and Usage Areas of Diethylene Glycol

Diethylene Glycol is a colorless, low volatility, low viscosity, hygroscopic liquid. Under normal conditions, diethylene glycol has no odor; However, under high vapor concentrations, a slightly sweet odor can be detected. It is completely miscible with water and many organic liquids.

Because of its high molecular weight, diethylene glycol is significantly less volatile than ethylene glycol and is sufficiently diverse for its specific uses. The reactivity and solubility of HOCH2CH2)2O form the basis for many applications.

Diethylene glycol is incompatible with strong oxidizing agents. HOCH2CH2)2O is also incompatible with strong bases. HOCH2CH2)2O reacts with sulfuric acid and other dehydrating agents, nitric acid, oxygen, hydrogen peroxide, perchloric acid and strong acids. Mixtures with sodium hydroxide decompose exothermically when heated to 446°F.

Usage areas

• HOCH2CH2)2O is used in the manufacture of unsaturated polyester resins, polyurethanes and plasticizers.
• As dye ink and solvent in textile dyeing;
• As a humectant in the tobacco industry;
• As a snow spray in Aircraft and Railways;
• It is used as a thinner in the glue industry.
• It is used as a selective solvent for aromatics in petroleum refining.
• It is used as a solvent in printing in the textile industry and as an auxiliary agent in the content of textile dyes.

HOCH2CH2)2O is used in the manufacture of unsaturated polyester resins, polyurethanes, and plasticizers. It is a solvent for nitrocellulose, resins, dyes, oils, and other organic compounds. It is also a component in brake fluid, lubricants and heating/cooking fuel. It is also used In personal care products (e.g. skin cream and lotions, deodorants).
