| Bis[2-(2-hydroxyethoxy)ethyl] ether Usage And Synthesis |
| Chemical Properties | liquid |
| General Description | Colorless to straw-colored liquid with a mild odor. Sinks and mixes with water. |
| Air & Water Reactions | Water soluble. |
| Reactivity Profile | Bis[2-(2-hydroxyethoxy)ethyl] ether is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides. May attack some forms of plastics [USCG, 1999]. |
| Health Hazard | Compound is nonirritating. No symptoms observed by any exposure route. |
