Monoethanolamine is a clear, colorless or pale yellow-colored, moderately viscous liquid with a mild, ammoniacal odor. Ethanolamines can be detected by odor as low as 2-3 ppm.
Monoethanolamine and triethanolamine are viscous, colorless, clear, hygroscopic liquids at room temperature; diethanolamine is a crystalline solid. All ethanolamines absorb water and carbon dioxide from the air and are infinitely miscible with water and alcohols. The freezing points of all ethanolamines can be lowered considerably by the addition of water.
Monoethanolamine is contained in many products,such as metalworking fluids. It is mainly an irritant.Traces may exist in other ethanolamine fluids.
When heated to decomposition it emits toxic fumes of /nitrogen oxides/.
Used for removing acidic gases from natural gas and petroleum gas, manufacturing non-ionic detergents, emulsifiers, etc;
Used as a gas chromatography stationary phase and solvent;
Ethanolamine is an intermediate used in the preparation of the carbamate insecticide hydrogen peroxide, and is also widely used as a purification solution for extracting acidic components from various gases, such as natural gas. Alkyl alcohol amide formed by ethanolamine and fatty acid is an effective foam synergist. Ethanolamine is also an intermediate of emulsifiers, used in the textile industry as an anti-static agent, anti moth agent, and cleaning agent. Hexahydrate piperazine can be prepared by cyclization and neutralization of ethanolamine hydrochloride, and piperazine can be used as a anthelmintic in the form of its phosphate or citrate salt.;
GB 2760-96 specifies that processing aids are allowed for use in the food industry.;
Monoethanolamine is mainly used as a plasticizer, vulcanizing agent, accelerator, and foaming agent for synthetic resins and rubber, as well as an intermediate for pesticides, pharmaceuticals, and dyes. It is also a raw material for synthetic detergents, emulsifiers in cosmetics, and other products. The textile industry uses it as a whitening agent, anti-static agent, anti moth agent, and cleaning agent for printing and dyeing. It can also be used as a carbon dioxide absorber, ink additive, and petroleum additive. Monoethanolamine is widely used as a purification solution for extracting acidic components from various gases, such as natural gas. Hexahydrate piperazine can be prepared by cyclization and neutralization of monoethanolamine hydrochloride. β - aminoethyl thiosulfate can be prepared by chlorination of monoethanolamine hydrochloride with sulfonyl chloride and substitution with sodium thiosulfate. This is a dye intermediate used in the production of condensed turquoise 13G. The reaction of monoethanolamine with carbon disulfide can produce the intermediate thiothiazoline, which has applications in the rubber and pharmaceutical industries.
Solvent. Organic synthesis involves removing carbon dioxide and hydrogen sulfide from gases. Gas chromatography stationary phase (maximum operating temperature 50 ºC, solvent ether), used for separating low-carbon alcohols, pyridine and its derivatives.
