Physical and chemical properties:
Ethanolamine is also called “aminoethanol”. Chemical formula HOCH2CH2NH2. Molecular weight 61.08. Colorless viscous liquid. Hygroscopic, with an ammonia smell. Specific gravity 1.0117 (25/4℃). Melting point 10.3℃. Boiling point 170.8℃. Refractive index 1.4539. Miscible with water, methanol, acetone, slightly soluble in benzene, ether, slightly soluble in n-pentane. Strong alkalinity, 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 a hygroscopic crystal with a melting point of 75~77℃. It is industrially prepared by the reaction of ethylene oxide and ammonia water. Ethanolamine is an important chemical raw material used to make medicines, fragrances, surfactants, coatings, emulsifiers, etc. It is also a leather softener and pesticide dispersant. It can also be used to purify gases and remove carbon dioxide and hydrogen sulfide from gases.
Uses:
Ethanolamine is used to prepare various drug compounds and inhibitors. Using ethanolamine as a raw material to synthesize substituted carboxyl compounds has strong anti-tumor activity. It is also used to synthesize aminoquinolone compounds with anti-malarial activity.
