Nitroethane water miscibility

Figure 14.4. Less common examples of ternary equilibria and some temperature effects, (a) The system 2,2,4-tri-methylpentane + nitroethane + perfluorobutylamine at 25°C the Roman numerals designate the number of phases in that region [Vreeland and Dunlap, J. Phys. Chem. 61, 329 (1957)]. (b) Same as (a) but at 51.3°C. (c) Glycol + dodecanol + nitroethane at 24°C 12 different regions exist at 14°C [Francis, J. Phys. Chem. 60, 20 (1956)]. (d) Docosane + furfural + diphenylhexane at several temperatures [Varteressian and Fenske, Ind. Eng. Chem. 29, 270 (1937)]. (e) Formic acid + benzene + tribromomethane at 70°C the pair formic acid/benzene is partially miscible with 15 and 90% of the former at equilibrium at 25°C, 43 and 80% at 70°C, but completely miscible at some higher temperature, (f) Methylcyclohexane + water + -picoline at 20°C, exhibiting positive and negative tieline slopes the horizontal tieline is called solutropic (Landolt-Bornstein II2b).

Nitroethane forms a colorless to oily liquid with a pleasant odor. It has a melting point of -50 Celsius, and a boiling point of 115 Celsius. Nitroethane is only very slightly soluble in water, but miscible in alcohol, and ether. It is also soluble in chloroform. Nitroethane forms explosive salts when treated with strong bases. It can be made by reacting ethyl bromide with sodium nitrite. 

Nitroethane is colorless transparent liquid with a relative density of 1.05, melting point of -89.52 °C, boiling point of 114—115 °C, flash point of 40-41 °C (open cup), refractive index of 1.3719. It is insoluble in water, and miscible with acetic acid, ethyl ether, chloroform and basic solution.
