Applications
1. Mainly used as an absorbent for acidic gases such as CO2, H2S, and SO2, nonionic surfactant, emulsifier, polishing agent, industrial gas purifier, lubricant. Iminodiethanol, also known as diethanolamine, is an intermediate for the herbicide glyphosate. Used as a gas purifying agent and as a raw material for organic synthesis.
2. Both morpholine and diethanolamine are intermediates in organic synthesis, for example, they can be used to produce certain optical bleaches in the textile industry. Fatty acid salts of morpholine can be used as preservatives, and morpholine can also be used in the production of intermediates or as a solvent. Diethanolamine is used as a reagent in analytical chemistry and as a stationary phase in gas chromatography, selectively retaining and separating alcohols, diols, amines, quinolines, thiols, thioethers, and water.
3. Diethanolamine is an important corrosion inhibitor, used in boiler water treatment, automotive engine coolants, drilling and cutting oils, and other types of lubricants for corrosion inhibition. It is also used as an absorbent for purifying acidic gases in gas streams. Used as an emulsifier in various cosmetics and pharmaceuticals. In the textile industry, it is used as a lubricant, as well as a wetting agent and softener, and as a raw material for other organic syntheses.
4. In adhesives, it is used as an acid absorbent, plasticizer, softener, emulsifier, etc. Also used as an absorbent for acidic gases (such as hydrogen sulfide, carbon dioxide, etc.) in petroleum gas and other gases. It is a raw material for the synthesis of pharmaceuticals, dye intermediates, and surfactants. Under acidic conditions, it is used as an emulsifier for oils and waxes, and as a softener for leather and synthetic fibers. In shampoos and light-duty detergents, it is used as a thickener and foam modifier. Also used in detergents, lubricants, brighteners, and engine piston descalers.
5. Used as a complexing agent for silver, cadmium, lead, and zinc plating.
6. Used as an analytical reagent, acid gas absorbent, softener and lubricant, and for organic synthesis
