Use

2-butanol is also known as 2-butanol, methyl ethyl alcohol, chemical formula is CH3CH2CHOHCH3. Molecular weight is 74.12. It is colorless liquid with a strong aroma of mint, flammable, volatile, with optical activity. The molecule has a chiral carbon atom, can be present in three forms of right-handed body, left-handed body and racemic body, dl-body: the relative density is 0.8063. Melting point is-114.7 ℃. Boiling point is 99.5 ℃, 45.5 ℃ (7.999 103Pa). The flash point is 34 ℃. The refractive index is 1.3978. d-body: the relative density is 0.8080. Boiling point is 99.5 ℃. The flash point is 24 ℃. The refractive index is 1.3954. Specific rotation is + 13.9 . l-body: the relative density is 0.8070. Boiling point is 99.5 ℃. The flash point is 28 ℃. The refractive index is 1.3955. Specific rotation is-13.51 (25 ℃). 2-butanol oxidation can generate methyl ethyl ketone and acetic acid. Slightly soluble in water (25 ℃ when 12.5ml/100ml), dissolved in acetone, benzene, miscible with ethanol and ether. This product interacts with water to form an azeotropic mixture, the product content is 68%, the total boiling point is 88.5 ℃. Rat oral is LD506480mg/kg. 2-butanol is the main raw material for producing methyl ethyl ketone, butyl acetate, sec-butyl acetate, and also used as a solvent and extraction agent, the raw materials of plasticizers, processing agents, herbicides, but also for synthesis of spices, flavors, coloring agents, wetting agent, cleaning agents and solvents of many natural resin, linseed oil and castor oil.
