Monoethanolamine

GB 2760-96 specifies it as an approved processing aid for the food industry. Monoethanolamine is primarily 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 and cosmetic emulsifiers. In the textile industry, it serves as a dyeing whitening agent, antistatic agent, mothproofing agent, and cleaning agent. It can also be used as a carbon dioxide absorbent, ink additive, and petroleum additive. Monoethanolamine is widely used as a purification solution for extracting acidic components from various gases (such as natural gas). Piperazine hexahydrate can be produced by cyclization and neutralization of monoethanolamine hydrochloride. Chlorination of monoethanolamine hydrochloride with thionyl chloride, followed by substitution with sodium thiosulfate, yields β-aminoethyl thiosulfate. This is a dye intermediate used in the production of Polycondensation Turquoise Blue 13G. The reaction of monoethanolamine with carbon disulfide produces mercaptothiazoline, an intermediate used in the rubber and pharmaceutical industries.
