Equation of Antoine

In chemistry, the equation of Antoine connects the Température of saturation and the Steam pressure saturating with a substance:

$\backslash \; log\_\; \{10\}\; (P\_s^o)\; =\; Has\; \backslash \; frac\; \{B\}\; \{T+C\}$

with $P\_s^o$ Pressure of vaporization of the substance at the temperature $T$.

$A,\; B$ and $C$ are the coefficients of Antoine, characteristics to each solution, which one finds in the reference books in chemistry.

By isolating the temperature one obtains:

$T\_s\; =\; \backslash \; frac\; \{B\}\; \{Has\; \backslash \; log\_\; \{10\}\; (P)\}-\; C$

who allows us to envisage with which temperature will boil a solution with a certain pressure, the atmospheric pressure for example (100 kPa, 760 mmHg,…)

For water the coefficients of Antoine with the pressure out of Pa and the temperature in °C are:

A=10,23

B=1750

C=235
