TCC’s Diethylene Glycol (DEG) is a straight-chain dihydric alcohol which is aliphatic terminated on both ends by a hydroxyl group. It is a clear, water-white, practically odorless, hygroscopic liquid at room temperature. DEG is a water-soluble liquid with a boiling point of 245 C. It is also soluble in many organic solvents.
DEG is produced by the partial hydrolysis of ethylene oxide. It is derived as a co-product in the production of ethylene glycol.
Diethylene glycol is used as a dehydrating agent for natural gas, a raw material for the production of plasticizers and polyester resin, and a widely used solvent. It is also used as a humectant in the tobacco industry and in the treatment of corks, glue, paper and cellophane as well as in the synthesis of morpholine and 1,4-dioxane.
Availability of DEG depends on the demand for derivatives of the primary product, ethylene glycol, rather than on DEG market requirements.
