MEA Monoethanolamine CAS NO 141-43-5

  

Product Application: 
Ethanolamine is also known as "aminoethanol". Chemical formula HOCH2CH2NH2. Molecular weight 61.08. Colorless viscous liquid. Easy to absorb moisture and smell of ammonia. Specific gravity 1.0117 (25/4℃). Melting point 10.3℃. Boiling point 170.8℃. Refractive index 1.4539. It is miscible with water, methanol and acetone, slightly soluble in benzene and ether, and slightly soluble in n-pentane. It is strongly alkaline, with a dissociation constant K=3.39×10-10 (25℃); the pH of 25% aqueous solution is 12.1, and it can absorb carbon dioxide in the air.

Monoethanolamine is mainly used as a plasticizer, vulcanizer, accelerator and foaming agent for synthetic resins and rubbers, as well as an intermediate for pesticides, medicines and dyes. It is also a raw material for synthetic detergents and emulsifiers for cosmetics. In the textile industry, it is used as a whitening agent, antistatic agent, anti-moth agent and detergent for printing and dyeing. It can also be used as carbon dioxide absorbent, ink additive, and petroleum additive. Monoethanolamine is widely used as a purification liquid to extract acidic components from various gases (such as natural gas). Piperazine hexahydrate can be obtained by cyclization and neutralization of monoethanolamine hydrochloride. Monoethanolamine hydrochloride is chlorinated with thionyl chloride and then replaced by sodium thiosulfate to produce β-aminoethyl thiosulfate. This is a dye intermediate used to produce polycondensation emerald blue 13G. The reaction of monoethanolamine with carbon disulfide can produce the intermediate sulfothiazoline which is used in the rubber and pharmaceutical industries.

Other solutions include Methylene Chloride,  Isopropyl Alcohol, Glacial Acetic Acid
