Overview	triethanolamine triethanolamine also known as trihydroxyethylamine, aminotriethanol. Colorless oily liquid, ammonia odor, easy to absorb water, open air and in the light to become brown. At low temperature, it is a colorless or light yellow cubic crystal. The melting point is 21.2 ℃, the boiling point is 335.4 ℃, 277 ℃(19.950kPa), 206~207 ℃(1.995kPa), the relative density is 1.1242, the refractive index is 1.4852. Kb = 2.5 x 10-10. 0.1mol/L aqueous solution pH was 10.5. Miscible with water, methanol and acetone. Soluble in benzene, ether, micro-soluble carbon tetrachloride, n-heptane. Strong bases, combined with protons, can be used for condensation reactions. In analytical chemistry, triethanolamine can be used as a stationary liquid for gas-liquid chromatography (the highest temperature is 75 ℃, and the solvent is methanol and ethanol) for separating pyridine and methyl substituents. In the analysis of Complexometric titration, can be used as a masking agent for interfering ions, such as in the solution of pH = 10, using EDTA titration of magnesium, zinc, cadmium, calcium, nickel plasma, the titanium, aluminum, iron, tin plasma can be masked with the reagent. In addition, with hydrochloric acid can also be prepared into a certain pH buffer solution. triethanolamine is mainly used in the manufacture of surfactants, liquid detergents, cosmetics, etc. It is one of the components of cutting fluid and antifreeze. In the polymerization of nitrile rubber as an activator, natural rubber and synthetic rubber vulcanization activator. Can also be used as oil, wax, pesticide and other emulsifiers, cosmetics moisturizing agent, stabilizer, textile softener, lubricating oil anti-corrosion additives. Triethanolamine can absorb gases such as carbon dioxide and hydrogen sulfide, and can remove acid gas in the purification of industrial gases such as coke oven gas. EDTA titration method is commonly used as a masking agent. The allowable concentration in air is 3 μg/g.
external use in dermatology	at present, the external use of biafen, a drug commonly used in dermatology departments of many hospitals to treat burns and skin wounds, is mainly composed of triethanolamine, triethanolamine can play a dual role of cleaning and drainage through the principle of penetration and capillary action, can increase the skin blood flow rate, help discharge exudate, and can also change the ratio between interleukin I and interleukin VI, stimulates fibroblast proliferation, increases collagen synthesis. Clinical for the treatment of radiation therapy caused by secondary erythema, I, II degree burn and not yet infected skin trauma. (1) skin damage caused by radiotherapy: it is recommended to apply 2~3 times a day, with equal intervals for each application, and gently massage to make skin absorption. (2) second degree burns and other skin wounds: after cleaning the wound, apply a thick layer of drug on the surface of the wound, and repeat the application to make the wound have a sufficient amount of drug. If necessary, please use wet compress. Do not use dry absorbent compress. (3) I Degree Burn: apply a thick layer until the skin no longer absorb the drug, and gently massage. 2-4 times a day.
Early strength agent	triethanolamine is a commonly used early strength agent in China's cement industry, the role of early strength agent is to accelerate the hydration process of cement in the presence of liquid phase in concrete, improve the early strength, although triethanolamine does not change the hydration products of cement, however, it can strengthen the activity of colloid generated by cement hydration, generate pressure on the surrounding, block the capillary channel, and intensify the adsorption, wetting and particle dispersion, to promote the formation of calcium sulphoaluminate hydrate reaction between C3A and gypsum, can improve the concrete density, impermeability and frost resistance, the role of early strength and improve the strength. When used in combination with inorganic salt materials, due to the hydration of cement itself and the reaction of inorganic salt and cement, it can play a catalytic role, so that the early strength effect is particularly significant.
Use	GB 2760-96 provides that the permitted use of food processing aids is limited to GMP. used as a detergent for removing carbon dioxide or hydrogen sulfide from a gas. Esters of triethanolamine and higher fatty acids are widely used as detergents, emulsifiers, humectants and lubricants, and also in the formulation of cosmetic balms. Triethanolamine is also used as a preservative and water repellent, Analytical reagents and solvents. As an activator in the polymerization of nitrile rubber, it can also be used as an emulsifier, stabilizer and softener for oils and waxes under acidic conditions. It is one of the components of synthetic fiber spinning finish. It is used as an additive in the polymerization of nitrile rubber, a concrete Accelerator, an oil emulsifier, and also used for cyanide-free electroplating gas chromatography stationary liquid (the highest temperature is 75 ℃, the solvent is methanol, ethanol), separation and analysis of oxygen-containing, nitrogen-containing compounds and aqueous samples.

production method	ethylene oxide and ammonia water are fed into the reactor at a reaction temperature of 30-40 ℃ and a reaction pressure of 70.9-304kPa, after dehydration and concentration at 90-120 ° C., the mixture of mono-, di-and triethanolamine is produced by condensation reaction and sent to three vacuum distillation columns for vacuum distillation, and fractions are cut off according to different boiling points, A final product of monoethanolamine, Diethanolamine and triethanolamine with a purity of 99% is obtained. In the reaction process, if the proportion of ethylene oxide is increased, the proportion of di-and triethanolamine is increased, and the yield of di-and triethanolamine can be increased. It is obtained by condensation reaction of ethylene oxide and ammonia water at 30-40 ° C. Under a pressure of 71-304 kPa, wherein the molar concentration ratio of ethylene oxide to ammonia is about 2.0. After the reaction, the reaction mixture was subjected to vacuum distillation in a rectification column, and a fraction in the vicinity of 360 ° C. Was obtained.
