  2. Volatility (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Volatility_(chemistry)

    In chemistry, volatility is a material quality which describes how readily a substance vaporizes. At a given temperature and pressure , a substance with high volatility is more likely to exist as a vapour , while a substance with low volatility is more likely to be a liquid or solid .

  3. Relative volatility - Wikipedia

    en.wikipedia.org/wiki/Relative_volatility

    Relative volatility is a measure comparing the vapor pressures of the components in a liquid mixture of chemicals. This quantity is widely used in designing large industrial distillation processes. [ 1 ] [ 2 ] [ 3 ] In effect, it indicates the ease or difficulty of using distillation to separate the more volatile components from the less ...

  4. Vapor–liquid equilibrium - Wikipedia

    en.wikipedia.org/wiki/Vapor–liquid_equilibrium

    In thermodynamics and chemical engineering, the vapor–liquid equilibrium (VLE) describes the distribution of a chemical species between the vapor phase and a liquid phase. The concentration of a vapor in contact with its liquid, especially at equilibrium , is often expressed in terms of vapor pressure , which will be a partial pressure (a ...

  5. Vapor pressure - Wikipedia

    en.wikipedia.org/wiki/Vapor_pressure

    The Antoine equation [3] [4] is a pragmatic mathematical expression of the relation between the vapor pressure and the temperature of pure liquid or solid substances. It is obtained by curve-fitting and is adapted to the fact that vapor pressure is usually increasing and concave as a function of temperature. The basic form of the equation is:

  6. Boiling point - Wikipedia

    en.wikipedia.org/wiki/Boiling_point

    The presence of non-volatile impurities such as salts or compounds of a volatility far lower than the main component compound decreases its mole fraction and the solution's volatility, and thus raises the normal boiling point in proportion to the concentration of the solutes. This effect is called boiling point elevation.

  9. Reid vapor pressure - Wikipedia

    en.wikipedia.org/wiki/Reid_vapor_pressure

    Reid vapor pressure (RVP) is a common measure of the volatility of gasoline and other petroleum products. [1] It is defined as the absolute vapor pressure exerted by the vapor of the liquid and any dissolved gases/moisture at 37.8 °C (100 °F) as determined by the test method ASTM-D-323, which was first developed in 1930 [2] and has been revised several times (the latest version is ASTM D323 ...
