Di ethylene glycol (DEG) is a colourless, odourless, stable liquid with a high boiling point and low viscosity. It is a member of a homologous series of dihydroxyalcohols. Its chemical properties are similar to those of mono ethylene glycol (MEG) and tri ethylene glycol (TEG) with some slight differences in viscosity, hygroscopicity and boiling point. It is produced by the hydration of ethylene oxide.
Synonyms: DEG, 2-(2-Hydroxyethoxy)ethanol; 2-(2-hydroxy-ethoxy)-ethanol; 2-(2-hydroxyethoxy)-ethanol; 2,2’-dihydroxyethylether; 2,2’-oxybis-ethano;2,2’-oxydi-ethano; 2,2’-oxyethanol; 2,2-Di(hydroxyethyl) ether
Applications of Di Ethylene Glycol Suppliers
Di ethylene glycol, like other glycols, is used widely in industry because of its high boiling point and its solvent and other useful properties including hygroscopicity, non-corrosiveness, freeze point depression, lubricating and plasticizing properties. It reacts readily, making it a popular intermediate for making a number of esters.
Specific applications of di ethylene glycol as distinct from other ethylene glycols include its use as an important chemical intermediate in the production of unsaturated polyester resins, polyurethanes and plasticizers. It is used as a dehydration agent in natural gas processing and in the treatment of corks, glue, paper and cellophane.
It is used in a number of industrial and consumer end products such as paints, coatings, surface treatment products, cleaning agents, lubricants, metal-working fluids, foams, adhesives, sealants, heat transfer and hydraulic fluids.
Storage and Handling
Ingestion of large amounts of di ethylene glycol may cause kidney and liver degeneration and even death. The liquid is a skin and eye irritant. Avoid contact with the skin, eyes and clothing by ensuring that appropriate measures are observed to avoid unnecessary exposure. This may include splash protection, the wearing of chemical-resistant boots, gloves and clothing, safety glasses or goggles, depending on the task being carried out. Inhalation of the vapour should be minimised with proper engineering controls and ventilation.
The product must not be stored near food, drugs or potable water supplies. Avoid contact with strong oxidizing agents and bases as di ethylene glycol is incompatible with these materials.
