Diethanolamine, chemical agent, Chinese name 2, 2 '- dihydroxydiethylamine, diethanolamine; Dihydroxyethylamine; 2,2 ` - iminodiethanol. Colorless viscous liquid or crystal. CAS:111-42-2.It is alkaline and can absorb gases such as carbon dioxide and hydrogen sulfide in the air.
1. Mainly used as an absorbent for acidic gases such as CO2, H2S, and SO2, non-ionic surfactants, emulsifiers, polishing agents, industrial gas purifiers, and lubricants. Diaminodiethanolamine, also known as diethanolamine, is an intermediate of the herbicide glyphosate. Used as a gas purifier, as well as a raw material for synthetic drugs and organic synthesis.
2. It is used as thickener foam improver in shampoo and light detergent, and as softener in synthetic fiber and leather production. Diethanolamine reacts with 70% sulfuric acid to dehydrate and cyclize to form morpholine (i.e. 1,4-oxazetidine). Morpholine and diethanolamine are both intermediates in organic synthesis, which can be used to produce certain optical bleaching agents in the textile industry. Morpholine's fatty acid salts can be used as preservatives, and Morpholine can also be used to produce the central inhibitory drug Forcodeine or as a solvent. Diethanolamine is used as a reagent and gas chromatography stationary liquid in analytical chemistry, selectively retaining and separating alcohols, diols, amines, pyridines, quinolines, piperazines, thiols, sulfides, and water.
3. Diethanolamine is an important corrosion inhibitor that can be used in boiler water treatment, automotive engine coolant, drilling and cutting oil, and other types of lubricating oils to play a corrosion inhibiting role. Still used as an absorbent for purifying acidic gases in natural gas. Used as an emulsifier in various cosmetics and drugs. In the textile industry, it can be used as a lubricant, wetting agent, softener, and other organic synthesis materials.
4. Used as an acid absorbent, plasticizer, softener, emulsifier, etc. in adhesives. It is also used as an absorbent for acidic gases (such as hydrogen sulfide, carbon dioxide, etc.) in petroleum gas, natural gas, and other gases. It is a raw material for synthesizing pharmaceuticals, pesticides, dye intermediates, and surfactants. Used as an emulsifier for oils and waxes under acidic conditions, and as a softener for leather and synthetic fibers. Used as thickener and foam improver in shampoo and light detergent. It is also used as a detergent, lubricant, brightener, and engine piston dust remover.
5. Used as a complexing agent for silver plating, cadmium plating, lead plating, zinc plating, etc.
6. Used as analytical reagents, acidic gas absorbers, softeners and lubricants, as well as for organic synthesis.
