    2,2'-Iminodiethanol Usage And Synthesis
    Chemical Propertiessolid or viscous liquid with an amine odour
    UsageDiethanolamine similar to triethanolamine (T775580) is used as a surfactant. It also has the potential to be a corrosion inhibitor by means of chemisorption.
    General DescriptionOily colorless liquid or solid white crystals. Slight rotten fish or ammonia odor. Denser than water.
    Air & Water ReactionsWater soluble.
    Reactivity Profile2,2'-Iminodiethanol is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. 2,2'-Iminodiethanol is hygroscopic. 2,2'-Iminodiethanol may be sensitive to exposure to air and light. 2,2'-Iminodiethanol can react with oxidizing materials, acids, CO2, copper alloys, aluminum, zinc, galvanized iron and copper.
    Health HazardIrritation of eyes and skin. Breathing vapors may cause coughing, a smothering sensation, nausea, headache.
    Fire HazardSpecial Hazards of Combustion Products: Irritating vapors are generated when heated.
