nature : a transparent colorless flammable volatile liquid polarity. Pure ethanol smells slightly crude pungent smells bad. -97.8 ° C melting point. Boiling point of 64.7 ° C and 49.9 ° C (53.3kPa), 34.8 ° C (26.7kPa), 21.2 ° C (13.3kPa), 12.1 ° C (survived), 5 ° C (5 .33 kPa), -6.0 ° C (2.67 kPa), -16.2 ° C (1.33kPa.Conclusion), -25.3 ° C (0.67kPa), -44.0 ° C (0.05). Compared to the density of 0.7915 (20 / 4 ° C), steam relative density 1.11 (Air = 1), the refractive index of 1.3287, flash point (open cup), 16 ° C, 473 ° C spontaneous combustion point, surface tension (25 ° C) 45. 05mN / m, vapor pressure (20 ° C) 12.265kPa, viscosity (20 ° C) 0.5945mPa s. With water, alcohol, ether, benzene, acetone and many other immiscible organic solvent. Methanol dissolved better performance than ethanol, a variety of inorganic salt can be dissolved, such as sulfonate sodium, calcium chloride and sodium sulfate Alkanolamine, copper sulfate, silver nitrate, chloride and sodium chloride. Steam and air to form explosive mixtures explosion limit of 6.0% -36.5% (volume).
