Description

Diethylene glycol

Physical properties of diethylene glycol and ethylene glycol are close. Diethylene glycol differs from ethylene glycol in the best solubility, smaller volatility, more high temperature of boiling and viscosity. Temperature of freezing of aqueous solution is slightly higher than at ethylene glycol, though is insignificant. The product represents viscous, transparent liquid almost not having smell and also as well as ethylene glycol, possessing very high hygroscopicity. Boiling temperature with atmospheric pressure 245C. Density at the room temperature is equal to 1,116 g/cm3., viscosity of-35,6 SPZ (MPa C), specific heat is 2,09 J / gk.

Use of diethylene glycol

Diethylene glycol is less often used as antifreeze in comparison with ethylene glycol. However rather it is connected not with the fact that it has properties, less suitable for this purpose (temperature of freezing of aqueous solutions and other characteristics differ not so considerably) and with the fact that ethylene glycol is more usual and available product and the volume of its production more. At the same time in certain cases use of diethylene glycol in mix ethylene glycol allows to receive antifreezes with higher operational properties.

Diethylene glycol is used as selective (selection) solvent for the purpose of extraction of different substances from oil and oil products, such as the xylol, toluene, benzene since well dissolves aromatic hydrocarbons and is not capable to dissolution of paraffinic and naphthenic type hydrocarbons. Thanks to more high solubility diethylene glycol is more preferable than ethylene glycol to these purposes. At the same time products of high degree of purity turn out.

Thanks to high hygroscopicity diethylene glycol is widely used for removal of water vapors from the gases which are pumped over on pipelines. It is necessary to delete water vapors for the purpose of prevention of education in pipelines of condensate and ice traffic jams. Also by means of diethylene glycol it is possible to purify gases and of other impurity, for example hydrogen sulfide and carbon dioxide gas.

Diglycol is applied as raw materials at synthesis of different polymeric materials: unsaturated polyester resinss, alkaliproof alkyd resins, heat-resistant and fire-resistant polyurethane, and also it is used at synthesis of the different modifying components for polymeric materials: plasticizers, stabilizers, antioxidants, polymerization activators, hardeners of epoxies.

Danger of diethylene glycol

Toxicity of diethylene glycol is lower than ethylene glycol. Couples do not constitute high danger at inhalation. However intake is also extremely dangerous.
