Production method

Feed the ethylene oxide and ammonia water are into the reactor; conduct the condensation reaction under a reaction temperature of 30-40 °C and a reaction pressure of 70.9-304 kPa to generate a mixture solution of mono-, di-and triethanolamine; after undergoing dehydration and concentration at 90-120 °Cand then send to three vacuum distillation tower for vacuum distillation; capture different fractions according to different boiling points, you can get over 99% purity of the finished product of ethanolamine, diethanolamine and triethanolamine. During the course of the reaction, if increase the proportion of ethylene oxide, the generation ratio of di-and tri-ethanolamine will increase so we can get higher di-and tri-ethanolamine yield.
It is manufactured through the condensation reaction between ethylene oxide and ammonia under 30~40 °C and the pressure 71~304 kPa, in which the molar concentration of ethylene oxide and ammonia ratio is about 2.0. After the reaction, perform vacuum distillation through the distillation column, cut off the fractions of about 360 °C.

Triethanolamine is a viscous, colourless/pale yellow liquid with a weak ammoniacal odour. Triethanolamine is incompatible with copper, copper alloys, galvanised iron, acids, and oxidisers. Reports indicate that in India itself, as many as six companies manufacture triethanolamine and it is manufactured by many different countries around the world. Global production and industrial application of triethanolamine is very extensive.
In industries, triethanolamine is used as a corrosion inhibitor in metal-cutting fluids; a curing agent for epoxy and rubber polymers; a copper–triethanolamine; in emulsifiers, thickeners, and wetting agents in the formulation of consumer products such as cosmetics, detergents, shampoos, and other personal products; and a neutraliser-dispersing agent in agricultural herbicide formulations. In brief, triethanolamine has wide applications as a corrosion inhibitor, a surface-active agent, and an intermediate in various products including metalworking fluids, oils, fuels, paints, inks, cement, cosmetic, and personal products and formulations of algicides and herbicides.

Dermatology drug for external use

At present, the dermatology of many hospitals commonly used the topical drug, Biafine for the treatment of burns and skin trauma with the main ingredient being triethanolamine. Triethanolamine can play a dual effect of cleaning and drainage through the principle of penetration and capillary action, being able to further increase the skin blood flow velocity and helping the discharge of exudate. It can also change the ratio between interleukin 1 and interleukin VI, stimulating the proliferation of fibroblast and increasing the collagen synthesis. It is clinically used for the treatment of secondary erythema caused by the radiation therapy as well as degree I, degree II burns and skin trauma that has not yet infected.
(1) radiation-induced skin damage: Recommended: application of 2 to 3 times with each administration within the same interval; gently massage to make the skin absorb it.
(2) Ⅱ-degree burns and other skin trauma: After cleaning the wounds, apply a thick layer of drug on the wound surface; repeat the application to make trauma be treated with a sufficient amount of drugs. If necessary, apply a moist wet dressing for wrapping. Do not use dry absorbent dressing.
(3) Ⅰ degree burns: Apply a thick layer until the skin doesn’t absorb the drug anymore and gently massage. Repeat 2 to 4 times a day.

Purification Methods

Shake the amine gently with Linde type 4A molecular sieves for 24hours, filter and fractionate it under a vacuum, and preferably in the presence of N2. Store it in dark stoppered bottles under N2 as it is hygroscopic, and turns brown in air and light. It has a strong ammoniacal odour (like diethanolamine). It is miscible with H2O, MeOH and Me2CO, and its solubilities at 25o in n-heptane, Et2O and *C6H6 are 0.4%, 1.6% and 4.2%, respectively. [See diethanolamine above, Beilstein 4 IV 1524.]

Early strength agent

Triethanolamine is currently a commonly used early strength agent used in China's cement industry with the effect of early strength agent being accelerating hydration process of the cement in the presence of liquid phase in the concrete to improve the early strength. Although triethanolamine does not change the hydration product of cement, it can enhance the activity of the colloid generated through the hydration of cement, producing pressure to surrounding regions, blocking the capillary channel, exacerbating the effect of the adsorption, wetting and dispersion of particles and so on, promoting the reaction of the formation of hydrated calcium sulfoaluminate between the C3A and gypsum. This can improve the density of concrete, anti-permeability and antifreeze property, playing the role of early strength and enhancing the strength.
When used in combination with inorganic salts, it can play a catalytic role due to the hydration of cement itself and the reaction between inorganic salts and cement, so that the effect of early strength is particularly significant in the case.

General description

Triethanolamine appears as colorless oily liquid with the smell of ammonia. It is easy to absorb water and will turn into brown color when being exposed to the air and the light. At low temperature, it will become colorless or pale yellow cubic crystal. It has a melting point of 21.2 ℃, boiling point of 335.4 ℃, 277 ℃ (19.950kPa), 206~207 ℃ (1.995kPa), relative density of 1.1242, the refractive index of 1.4852. Its Kb is 2.5 × 10-10 with the pH of its 1.0 mol/L aqueous solution being 10.5. It is miscible with water, methanol and acetone. It is soluble in benzene, ether, slightly soluble in carbon tetrachloride, n-heptane. It is a kind of strong alkaline, combining with protons, can be used for condensation reaction.
In analytical chemistry, triethanolamine can be used as the stationary phase for the gas liquid chromatography (the maximum temperature is 75 ℃ with the solvent being methanol and ethanol), used for the separation of pyridine and methyl substitutes. In the complexometric titration and other analysis, it can be used as a masking agent for interfering ions. For example, in a solution of pH = 10, when we apply EDTA for titration of magnesium, zinc, cadmium, calcium, nickel and other ions, the reagent can be used for masking titanium, aluminum, iron, tin and some other ions. In addition, it can also be dubbed with hydrochloric acid into a buffer solution of a certain pH value.
Triethanolamine is mainly used in the manufacture of surfactants, liquid detergents, cosmetics and so on. It is one of the components of cutting fluid and antifreeze fluid. During the nitrile rubber polymerization, it can be used as an activator, being the vulcanization activator of natural rubber and synthetic rubber. It can also be used as the emulsifiers of oil, wax and pesticides, the moisturizer and stabilizer of cosmetics, textile softeners as well as the anti-corrosion additives of lubricants. Triethanolamine is also capable of absorbing carbon dioxide and hydrogen sulfide and other gases. During the cleaning of the coke oven gas and other industrial gases, it can be used for removal of acid gases. It is also a commonly used masking agent in the EDTA titration assay.
