Diethanolamine (DEA), with CAS No. 111-42-2 and molecular formula C\u2084H\u2081\u2081NO\u2082, is a multifunctional amino alcohol characterized by its dual hydroxyl (-OH) and amino (-NH) functional groups, strong polarity, and excellent chemical reactivity.<\/p>\n
Gas Treatment:<\/strong> Efficient absorbent for removing acidic gases (CO\u2082, H\u2082S) from natural gas, refinery gas, and flue gas; widely used in oil & gas processing and carbon capture systems (CCS) due to its high absorption capacity and low volatility (superior to monoethanolamine in corrosion resistance).<\/p>\n Chemical Synthesis:<\/strong> Intermediate for producing surfactants (e.g., alkylolamides, ethoxylates), plasticizers, and polyurethane foam (chain extenders); raw material for corrosion inhibitors, lubricant additives, and textile auxiliaries.<\/p>\n Cosmetics & Personal Care:<\/strong> pH adjuster, emulsifier, and humectant in shampoos, conditioners, lotions, and soaps; enhances product stability, foam quality, and skin\/hair compatibility.<\/p>\n Metalworking & Corrosion Inhibition:<\/strong> Component of metal cutting fluids, rust inhibitors, and cleaning agents; forms a protective chelate film on metal surfaces to prevent oxidation and corrosion, suitable for steel, aluminum, and copper processing.<\/p>\n Textiles & Dyes:<\/strong> Softener, leveling agent, and dye-fixing agent in textile printing and dyeing; improves fabric hand feel, color uniformity, and fastness to washing.<\/p>\n Agrochemicals & Pharmaceuticals:<\/strong> Intermediate for pesticide formulations (e.g., herbicides, fungicides) and pharmaceutical synthesis; enhances solubility and bioavailability of active ingredients.<\/p>\n Other Fields:<\/strong> Used in cement grinding aids to improve grinding efficiency; as a plasticizer for cellulose-based materials and a stabilizer for rubber products.<\/p>","protected":false},"excerpt":{"rendered":" Diethanolamine (DEA), with CAS No. 111-42-2 and molecular formula C\u2084H\u2081\u2081NO\u2082, is a multifunctional
