Diethylene glycol monoethyl ether is a chemical compound from the group of glycol ethers .
Extraction and presentation
Diethylene glycol monoethyl ether can be made from ethyl glycol and ethylene oxide . More than 1000 tons are produced per year.
properties
Diethylene glycol monoethyl ether is a colorless liquid with a sweet, musty to fruity odor. It has a dynamic viscosity of 3.85 mPa · s at 25 ° C. The odor threshold of the compound is 1.2–6 mg · m −3 .
use
Diethylene glycol monoethyl ether is used as a solubilizer, non-volatile solvent , paint finisher. It is contained in non-aqueous wood stains, stamp inks, leather dyes, printing pastes and printing inks. The use for the production of food packaging items is prohibited in Germany. It has been replaced industrially by other similar solvents.
safety instructions
The vapors of diethylene glycol monoethyl ether can form an explosive mixture with air ( flash point 90 ° C, ignition temperature 190 ° C).
