2-ethoxyethanol, and ethyl glycol is a colorless, slightly smelling of diethyl ether, poisonous liquid, which counts both the alcohols, as well as to the ethers.
Preparation and Properties
Ethyl glycol is prepared by the reaction of ethylene with ethanol. The colorless liquid is miscible with water and many organic solvents. 2- ethoxy ethanol is an excellent solvent for many organic, and polymeric materials such as nitrocellulose or celluloid, cellulose ethers, resins (such as novolak and resole ), chlorinated rubber, polyvinyl acetate, polyvinyl butyral, polyacrylic acid esters, as well as vegetable oils such as castor oil and linseed oil. Therefore, it is industrially used in the production of coatings of cellulose nitrate and cellulose ethers, usually in a mixture with other organic solvents such as mineral spirits, ethanol or toluene.
2 -ethoxyethanol irritates eyes and mucous membranes, can be absorbed through the skin and is involved in many animal species toxic for reproduction which is why the use is currently restricted. In the presence of oxygen can form from Ethylglycol explosive peroxides; in contact with aluminum, this can be corroded by 2- ethoxy ethanol with evolution of hydrogen gas.
