Diethylene glycol
Chemical Name: Diethylene glycol
Trade Name: DEG
Introduction:
Diethylene glycol (DEG) is a clear liquid , which is produced from the reaction between water and ethylene oxide. In fact, it is the co-product of ethylene glycol alongside with TEG. It is miscible with water, alcohols, acetone, ether and has the chemical formula of C4H10O3.
In terms of chemicals properties, di ethylene glycol is similar to MEG (monoethylene glycol), but it has a higher specific gravity, viscosity and boiling point.
General Applications:
Diethylene glycol is used in the manufacture of unsaturated polyester resins, plasticizers and polyurethanes. It is also used as textile lubricant, solvent in textile dyeing and printing, humectant, selective solvent for aromatics in petroleum refining, plasticizer for paper, cork and synthetic sponges, raw material for the production of esters used as emulsifiers and demulsifiers, constituent of hydraulic fluids and solvent in printing inks.

Safety, Handling & Storage:
Full information on the safety, handling and storage of Diethylene glycol (DEG) is available in the corresponding Material Safety Data Sheet (MSDS).
Diethylene glycol (DEG) is an organic compound with the formula (HOCH2CH2)2O. It is a colorless, practically odorless, and hygroscopic liquid with a sweetish taste. It is a four carbondimer of ethylene glycol. It is miscible in water, alcohol, ether, acetone, and ethylene glycol.[2] DEG is a widely used solvent.[3] It can be a contaminant in consumer products; this has resulted in numerous epidemics of poisoning since the early 20th century.
