    Applications / Functions of Aminoethanol liquid

    Aminoethanol CAS 141-43-5 is used in the preparation of various pharmaceutical compounds and inhibitors. Aminoethanol liquid is used as a raw material for the synthesis of substituted carboxyl compounds with strong antitumor activity. It is also used to synthesize aminoquinolones with antiplasmodial activity.

    Aminoethanol Raw Materials is used as gas chromatography stationary liquid and solvent.

    GB 2760-96 stipulates that it is permitted to be used as processing aids for food industry.

    Aminoethanol Raw Materials are mainly used as plasticizers, vulcanizing agents, accelerators and foaming agents for synthetic resins and rubbers, as well as intermediates for pesticides, pharmaceuticals and dyes. It is also a raw material for synthetic detergents and emulsifiers for cosmetics. It is also used in the textile industry as a whitening agent for printing and dyeing, an antistatic agent, an antimoth-eaten agent, a detergent, etc. Aminoethanol liquid can also be used as a carbon dioxide absorber, an ink auxiliary, and a petroleum additive.Aminoethanol CAS 141-43-5 is widely used as a purifying liquid for the extraction of acidic components from a wide variety of gases (e.g., natural gas). Piperazine hexahydrate can be produced by cyclization and neutralization of monoethanolamine hydrochloride. By chlorination of monoethanolamine hydrochloride with sulfoxide chloride and substitution by sodium thiosulfate, β-aminoethyl thiosulfate can be produced. This is a dye intermediate, used in the production of condensed emerald blue 13 G. The reaction of monoethanolamine with carbon disulfide can produce thiothiazoline, an intermediate with applications in the rubber and pharmaceutical industries.

    Aminoethanol liquid

    Aminoethanol CAS 141-43-5 is also known as 2-aminoethanol, 2-hydroxyethylamine and monoethanolamine. Ethanolamine is an intermediate in the preparation of the carbamate insecticide diclofenac, and is also widely used as a purification fluid for the extraction of acidic components from a variety of gases (e.g., natural gas). Alkyl alcohol amides produced from ethanolamine and fatty acids are effective foam boosters.Aminoethanol Raw Materials is also an intermediate for emulsifiers and is used in the textile industry as an antistatic agent, mothproofing agent, and cleaning agent. Piperazine hexahydrate is produced by cyclization and neutralization of ethanolamine hydrochloride, which is used as an anthelmintic in its phosphate or citrate form.

    Aminoethanol Raw Materials is used to remove acid gas from natural gas and petroleum gas, and to manufacture nonionic detergent and emulsifier.

    Aminoethanol liquid is used to separate low carbon alcohols, pyridine and its derivatives.

    Physicochemical Property of Aminoethanol liquid

    Aminoethanol liquid is also called "aminoethanol". Chemical formula HOCH2CH2NH2, molecular weight 61.08, colorless viscous liquid. It is easy to absorb moisture and has the odor of ammonia. Specific gravity 1.0117(25/4℃). Melting point 10.3℃. Boiling point 170.8℃. Refractive index 1.4539. Mutually soluble in water, methanol, acetone, slightly soluble in benzene, ether, slightly soluble in n-pentane. Strong alkaline, dissociation constant K=3.39×10-10(25℃); 25% aqueous solution pH is 12.1, can absorb carbon dioxide in the air. Its hydrochloride is easy to hygroscopic crystals, melting point 75 ~ 77 ℃. Aminoethanol liquid is an important chemical raw material used in the manufacture of drugs, spices, surfactants, paints, emulsifiers, etc. It is also a softener for leather and a dispersant for pesticides; it can also be used in the purification of gases to remove carbon dioxide and hydrogen sulphide from the gases.

    Aminoethanol CAS 141-43-5

    Aminoethanol CAS 141-43-5 is a colorless transparent viscous liquid at room temperature, with hygroscopicity and ammonia odor. Miscible with water, ethanol and acetone, slightly soluble in ether and carbon tetrachloride.

    production methodprocess of Aminoethanol liquid

    • Aminoethanol CAS 141-43-5 can be produced by the reaction of ammonia and ethylene oxide. Ethylene oxide, aqueous ammonia solution and circulating ammonia together into the stainless steel reactor, equipped with a cooling device, the reaction temperature of 30 ~ 40 ℃, reaction pressure of 0.7 ~ 3MPa. reaction products into the de-ammonia tower, the ammonia returned to the ammonia absorber preparation of aqueous ammonia solution, the product of the bottom of the tower by evaporation, concentration and drying dehydration that is, the crude ethanolamine. Using decompression distillation will be a ethanolamine, diethanolamine and triethanolamine were evaporated, the purity can reach 98% to 99%, the conversion rate of ethylene oxide is close to 100%, the ethanol amine yield is about 95%. In addition, there are still a small amount of by-products of polyether generation, in the raw material with a small amount of carbon dioxide can reduce the generation of by-products.
    • Aminoethanol liquid often exists in phospholipids, and often coexist with choline, so it is also known as cholamine. Ethanolamine is also found in serum protein putrefactive fermentation broth. Industrially ethanolamine can be made by reacting ammonia with ethylene oxide. Ethylene oxide, ammonia into the reactor, at a reaction temperature of 30-40 ℃, the reaction pressure of 70.9-304kPa, the condensation reaction to generate one, two, three ethanolamine mixture, at 90-120 ℃ after dehydration and concentration, sent to three decompression distillation tower for decompression distillation, according to the different boiling points intercepted fractions, you can get up to 99% purity of one ethanolamine, diethanolamine and triethanolamine. Finished products. In the reaction process, such as increasing the proportion of ethylene oxide, the proportion of di- and triethanolamine generation increases, can improve the yield of di- and triethanolamine.
    • It is condensed from ethylene oxide and ammonia at 30~40℃ and 70.1~304kPa, and it is a mixture of mono-, di- and triethanolamine, dehydrated and concentrated at 90~120℃, and then distilled under reduced pressure in a distillation tower, and the Aminoethanol liquid is obtained by intercepting the fraction at 168~174℃.
