Antoine equation

Antoine equation

[′an‚twän i‚kwā·zhən]
(physics)
The empirical relationshipbetween temperature and vapor pressure of liquids; log P = B-A /(C + T), where A, B, C are experimental constants, T is absolute temperature, and P is vapor pressure.

where [[P.sub.i].sup.SAT] corresponds to the vapor pressure of component i, and [A.sub.i] [B.sub.i], and [C.sub.i], are the constants of the Antoine Equation. Therefore, the total pressure of the gas phase can be calculated as
For this, we may use the Antoine equation (Antoine, 1888) in the form:
They also used the Antoine equation in the form of Equations (12) and (13) for [p.sub.1.sup.*] and [p.sub.2.sup.*], respectively, with [A.sub.1] = 14.018, [B.sub.1] = 3215.228, [C.sub.1] = - 80.532; [A.sub.2] = 13.85459, [B.sub.1] = 3224.816, and [C.sub.2] = -74.824.
