Fractionally distil the amine twice, then fractionally crystallise it from its melt. Its solubility in H2O is 10% at 20o. [Perrin & Dempsey Buffers for pH and Metal Ion Control Chapman & Hall, London 1974, Beilstein 4 H 283, 4 II 729, 4 III 689, 4 IV 1514.]
To scrub gases as indicated under ethanolamine. Diethanolamine can be used with cracking gases and coal or oil gases which contain carbonyl sulfide that would react with monoethanolamine. As rubber chemicals intermediate. In the manufacture of surface active agents used in textile specialties, herbicides, petroleum demulsifiers. As emulsifier and dispersing agent in various agricultural chemicals, cosmetics, and pharmaceuticals. In the production of lubricants for the textile industry. As humectant and softening agent. In organic syntheses.
Irritation of eyes and skin. Breathing vapors may cause coughing, a smothering sensation, nausea, headache.
Oily colorless liquid or solid white crystals. Slight rotten fish or ammonia odor. Denser than water.
solid or viscous liquid with an amine odour
2,2'-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.
ChEBI: A member of the class of ethanolamines that is ethanolamine having a N-hydroxyethyl substituent.
Diethanolamine is contained in many products, as a
metalworking fuid. Traces may exist in other etha-
Air & Water Reactions
Diethanolamine similar to triethanolamine (T775580) is used as a surfactant. It also has the potential to be a corrosion inhibitor by means of chemisorption.
Special Hazards of Combustion Products: Irritating vapors are generated when heated.
