Monoethanolamine is an organic compound with molecular formula c2h7no, colorless liquid. It is used to remove acid gas from natural gas and petroleum gas and manufacture non-ionic detergent, emulsifier, etc Name: monoethanolamine Abbreviation: MEA Alias: 2-aminoethanol; 2-Aminoethyl alcoho CAS: 141-43-5 Molecular formula: c2h7no Molecular weight: 61.0837 Melting point: 10.5 ℃ Boiling point: 170 ℃ Freezing point: – 5 ℃ Refractive index: 1.4540 Relative density: 1.0180 (20 / 4 ℃) Flash point: 93.3 ℃ Monoethanolamine is a colorless viscous liquid with ammonia smell at room temperature, soluble in water, strongly alkaline, miscible with water, ethanol and acetone, slightly soluble in ether and carbon tetrachloride. At 25 ℃, the solubility in benzene is 1.4%, in ether is 2.1%, and in carbon tetrachloride is 0.2%. It can absorb carbon dioxide and hydrogen sulfide and release the absorbed gas after heating. It is combustible and may burn in case of open fire and high heat. Vapors are toxic. Some are hygroscopic. It has emulsifying and foaming effects. It can form salts with inorganic and organic acids and esters with anhydride. The hydrogen atom in its amino group can be replaced by acyl halide, haloalkane, etc
