Diethanolamine Product Code: LJ-036 Product Specifications； 99.9% Origin of the product: Dow in the United States (13,500 yuan/ton). Packaging of the product: 200 kg/barrel. Description of properties: See “Ethanolamine”. Its main physical properties are as follows: melting point 28.0°C, boiling point 269.1°C, 217°C (20 kPa), 154–155°C (1.33 kPa), 20°C (1.33 Pa); relative density 1.0828 (20/20°C); dynamic viscosity (40°C) 196.4 mPa·s; refractive index 1.4476; flash point 146°C. Soluble in water, methanol, propanone ； At 25°C, its solubility in benzene is 4.2%, in ether it is 0.8%, and in carbon tetrachloride it is less than 0.1%. It is a colorless to slightly yellowish viscous liquid when melted. It has an ammonia-like odor and is hygroscopic. It is alkaline. Its 0.1N aqueous solution has a pH of 11.0, and it can absorb carbon dioxide and hydrogen sulfide from the air. Production method: Diethanolamine is obtained by the reaction of ethylene oxide with ammonia; ethanolamine and triethanolamine are also produced as by-products. Ethylene oxide and ammonia are fed into the reactor, where a condensation reaction takes place at a reaction temperature of 30–40°C and a reaction pressure of 70.9–304 kPa to produce a mixture of mono-, di-, and triethanolamine. After dehydration and concentration at 90–120°C, this mixture is sent to three vacuum distillation columns for vacuum distillation; fractions with different boiling points are separated, thereby yielding monoethanolamine, diethanolamine, and triethanolamine products with a purity of 99%. During the reaction process, increasing the proportion of ethylene oxide leads to an increased yield of diethanolamine and triethanolamine, thereby improving their overall yield. Uses: Diethanolamine is primarily used as an absorbent for acidic gases such as CO2, H2S, and SO2, as a non-ionic surfactant, emulsifier, polishing agent, industrial gas purifier, and lubricant. It is used as a thickening agent and foam improver in shampoos and mild detergents, and as a softener in the production of synthetic fibers and leather. Diethanolamine reacts with 70% sulfuric acid to undergo dehydration and cyclization to form morpholine (i.e., 1,4-oxazacyclohexane). Both morpholine and diethanolamine are intermediates in organic synthesis; for example, they can be used to produce certain optical bleaching agents in the textile industry. The fatty acid salts of morpholine can be used as preservatives, and morpholine can also be used to manufacture the central nervous system depressant pholcodine or as a solvent. Diethanolamine is used in analytical chemistry as a reagent and as a stationary phase in gas chromatography, enabling the selective retention and separation of alcohols, diols, amines, pyridines, quinolines, piperazines, thioalcohols, thioethers, and water.
