Diethylene glycol diethyl ether is a chemical compound from the group of glycol ethers .

Extraction and presentation

Diethylene glycol diethyl ether can be obtained by reacting ethylene glycol monoethyl ether with diethyl sulfate .

properties

Diethylene glycol diethyl ether is a slightly volatile, colorless, oily, hardly flammable liquid with a characteristic odor that is miscible with water. According to Antoine, the vapor pressure function results from ln (P) = A− (B / (T + C)) (P in kPa, T in K) with A = 17.5759, B = 5675.286 and C = −21.321 im Temperature range from 363 to 453 K. The enthalpy of vaporization at the boiling point is 48.3 kJ · mol −1 .

use

Diethylene glycol diethyl ether is used as a high boiling point solvent .

safety instructions

The vapors of diethylene glycol diethyl ether can form an explosive mixture ( flash point 70 ° C, ignition temperature 174 ° C) when heated with air .
