What is Monoethanolamine?

Monoethanolamine is the most important product among amino alcohols, accounting for more than 90% of the production. Ethanolamine includes monoethanolamine (MEA), diethanolamine (DEA), and triethanolamine (TEA). It is not only the core raw material of the metalworking fluid industry, but also used in shampoo, laundry detergent, hair dye and other products in daily life. Monoethanolamine is also used in the manufacturing process of textiles.

Monoethanolamine is also known as 2-aminoethanol, monoethanolamine, beta-aminoethanol, 2-hydroxyethylamine, beta-hydroxyethylamine, hydroxyethylamine and cholamine. There are three types of ethanolamine: -ethanolamine, diethanolamine and triethanolamine. Monoethanolamine is commonly known as ethanolamine. This article is monoethanolamine (see other articles). Monoethanolamine is present in phospholipids, coexisting with choline; it can also be found in fermentation broths of serum albumin. Colorless viscous liquid. Has a strong hygroscopicity. There is ammonia smell. The relative molecular mass is 61.01. The relative density is 1.0180. Melting point 10.3 ℃. Boiling point 170.8 ℃. 70~72℃(1.600×103Pa), 58℃(0.667×103Pa). Flash point 93 ℃. Refractive index 1.4541. Viscosity 18.95 mPa·s (25°C), 5.03 (60°C). Slightly soluble in benzene (1.4 at 25°C), ether (2.1), carbon tetrachloride (0.2) and n-hexane (0.1). Miscible with water, methanol, ethanol and acetone. Strongly alkaline, 25% aqueous solution pH=12.1. It can absorb acid gas, and after heating, it can release the absorbed gas, such as absorbing carbon dioxide from air, absorbing sulfur dioxide and carbon dioxide from mixed gas. Emulsifying and foaming. It can form salts with inorganic or organic acids, and esters with acid anhydrides. Its amino and hydroxyl groups can have corresponding effects, respectively. Oral LD5010200mg/kg for rats.

Monoethanolamine Uses

  1. Monoethanolamine is used in the preparation of various pharmaceutical compounds and also preventions. The replaced carboxyl compounds were manufactured with ethanolamine as resources, which had strong antitumor activity. It is likewise made use of to manufacture aminoquinolones with anti-plasma bloodsucker task.
  2. Monoethanolamine is utilized as gas chromatography fixative and solvent.
  3. Monoethanolamine is a handling help for food industry that is permitted to be used in GB 2760-96.
  4. Monoethanolamine is an intermediate for the preparation of carbamate pesticides, dioxycarb, and is likewise commonly made use of as a filtration liquid for extracting acidic components from various gases (such as gas). Alkyl alcohol amides created from ethanolamine as well as fatty acids work foam boosters. Monoethanolamine is additionally an intermediate of emulsifier, made use of in textile industry as antistatic agent, moth repellant, cleansing agent. Piperazine hexahydrate can be prepared by cyclization as well as neutralization of ethanolamine hydrochloride, and piperazine can be made use of as an anthelmintic in the form of its phosphate or citrate.
  5. Monoethanolamine is the solvent. Organic synthesis, elimination of co2 as well as hydrogen sulfide from gases. Gas chromatography fixed liquid (optimum temperature 50 ℃, solvent is ether), made use of to divide low-carbon alcohols, pyridine and its by-products.

Monoethanolamine Production Method

Monoethanolamine can be prepared by the reaction of ammonia as well as ethylene oxide.
Ethylene oxide, liquid ammonia service and also distributing ammonia enter the reactor made of stainless steel along with cooling down tool, the response temperature is 30 ~ 40 ℃, as well as the reaction pressure is 0.7 ~ 3MPa. The reaction item gets in the deamination tower, the removed ammonia is gone back to the ammonia absorber to prepare a liquid ammonia service, as well as the product at the end of the tower is vaporized, focused, dried out as well as dried out to acquire unrefined ethanolamine. The monoethanolamine, diethanolamine and also triethanolamine are respectively distilled by vacuum cleaner distillation, the purity can get to 98%-99%, the conversion rate of ethylene oxide is close to 100%, and the return of Monoethanolamine has to do with 95%. In addition, a percentage of by-product polyether is still generated, and a percentage of carbon dioxide is included in the raw product to decrease the generation of byproducts.

Monoethanolamine is commonly located in phospholipids as well as usually exists together with choline, so it is additionally called choline. Ethanolamine is likewise discovered in serum albumin putrefied fermentation brew. Industrial Monoethanolamine can be gotten by the response of ammonia as well as ethylene oxide. The ethylene oxide as well as ammonia water are sent into the activator, and at the reaction temperature level of 30-40 ° C and the reaction stress of 70.9-304kPa, the condensation reaction is accomplished to create a mixed remedy of mono-, di- and also triethanolamine, which is dried out as well as concentrated at 90-120 ° C. After that, it is sent out to 3 vacuum cleaner purification towers for vacuum distillation, as well as the fractions are removed according to different boiling points, and the completed items of monoethanolamine, diethanolamine and triethanolamine with a purity of 99% can be obtained. In the response procedure, if the percentage of ethylene oxide is enhanced, the proportion of di- and triethanolamine created boosts, which can enhance the return of di- and also triethanolamine.
