What does the Antoine equation calculate?
The Antoine equation is a class of semi-empirical correlations describing the relation between vapor pressure and temperature for pure substances. The Antoine equation is derived from the Clausius–Clapeyron relation.

What is Delta H of acetone?
Selected ATcT enthalpy of formation based on version 1.118 of the Thermochemical Network
| Species Name | Formula | ΔfH°(298.15 K) |
|---|---|---|
| Acetone | CH3C(O)CH3 (cr,l) | -247.48 |
How do you convert Antoine coefficients?
Example : Antoine’s coefficients for ethanol with formula log10(P)=A-B/(C+T) (P in bar, T in kelvin) are : A=5.37229, B=1670.409, C=-40.191 for the temperature range 273 to 351 K. Equivalent coefficients for formula ln(P)=A-B/(C+T) (P in mmHg, T in kelvin) are : A=18.99031, B=3846.25886, C=-40.191.
Is Antoine equation in Celsius or Kelvin?
It is relatively easy to convert the Antoine coefficients based on using Celsius scale temperatures to make them suitable for using Kelvin scale temperatures. All that is required is to subtract 273.15 from the C coefficient.
What is the Wagner equation?
2. Wagner equation and objective function. The Wagner equation can be used to estimate vapour pressure for a fixed temperature value according to [6]:(1) ln P sat P c = A τ + B τ 1.5 + C τ 2.5 + D τ 5 1 – τ , where τ = 1 – T T c and Pc is the critical pressure and Tc is the critical temperature.
How do you find the density of acetone?
- Density of acetone in a few select units of density measurement:
- Density of acetone g cm3 = 0.78 g/cm³
- Density of acetone g ml = 0.78 g/ml.
- Density of acetone g mm3 = 0.00078 g/mm³
- Density of acetone kg m3 = 784.5 kg/m³
- Density of acetone lb in3 = 0.028 lb/in³
- Density of acetone lb ft3 = 48.97 lb/ft³
How do you find the density of acetone vapor?
For example, acetone has a vapour density of 2 in relation to air. That means acetone vapour is twice as heavy as air. This can be seen by dividing the molecular weight of Acetone, 58.1 by that of air, 28.97, which equals 2.
What is the density of acetone in g mL?
0.791 g/mL
density. 0.791 g/mL at 25 °C (lit.)
What is the latent heat of acetone?
Latent heat of vaporization for fluids like alcohol, ether, nitrogen, water and more.
| Product | Latent Heat of Evaporation*) – he – | |
|---|---|---|
| (kJ/kg) | (Btu/lb) | |
| Acetic acid | 402 | 173 |
| Acetone | 518 | 223 |
| Alcohol | 896 | 385 |
Where is the Antoine equation used?
The Antoine equation is a semi-empirical equation which expresses vapour pressure as a function of temperature. A. new, rapid and highly accurate method for obtaining its three constants from experimental data is presented and applied to ethanol, water and 14 anaesthetic substances.
What is Cox chart?
[′käks ‚chärt] (chemistry) A straight-line graph of the logarithm of vapor pressure against a special nonuniform temperature scale; vapor pressure-temperature lines for many substances intersect at a common point on the Cox chart.
