while the boiling point is 83oC. This liquid is miscible with water and is stable under normal conditions. Isopropyl alcohol is a colourless, clear, and flammable liquid. Moreover, it oxidizes violently to produce acetone. When considering the applications of this alcohol, it is useful as a ...
The normal boiling point of acetone is 56.2 degrees C and the molar heat of vaporization is 32.0 kJ/mol. At what temperature will acetone boil under a pressure of 50.0 mm of Hg? The standard enthalpy of vaporization (Delta H_vap) of ethanol (CH_3...
Its relative density is 1.0362 (25/4 °C), its melting point is -60 °C, and its boiling point is 188.2 °C. It is miscible with water, acetone, ethyl acetate and chloroform, and soluble in ether. Although it has little solubility for hydrocarbons,...

With the help of some of the above mentioned solvents, partial crystallization of the PPE can be achieved. PPE is generally only partially soluble in aliphatic hydrocarbons, acetone, several alcohols and tetrahydrofurane. PPE exhibits good resistance against water, acids and alkalis. (Kroschwitz, ...
