In closed condition, at a certain temperature, in phase with solid or liquid balance Is called saturation Vapor pressure 。 The same substance has different saturated The vapor pressure increases with the increase of temperature. The saturated vapor pressure of pure solvent is higher than that of solution; For the same substance, the saturated vapor pressure of solid is lower than that of liquid.

Chinese name: Saturated vapor pressure
Foreign name: saturated vapor pressure

Meaning: Pressure of vapor in equilibrium with solid or liquid

At 30 ℃, the saturated vapor pressure of water is 4132.982Pa, and that of ethanol is 10532.438Pa. At 100 ℃, the saturated vapor pressure of water increases to 101324.72Pa, and that of ethanol is 222647.74Pa. Saturated vapor pressure is an important factor of liquid physical property , liquid boiling point , the relative volatility of liquid mixture, etc.

For example, the water in the cup will become less and less due to continuous evaporation. If the pure water is put in a closed container and the air above is pumped away. When the water evaporates continuously, the pressure of the vapor phase above the water surface, that is, the pressure of the water vapor, increases continuously. However, when the temperature is fixed, the vapor pressure will eventually stabilize at a fixed value, and the vapor pressure at this time is called the saturated vapor pressure of water at this temperature. When the value of vapor phase pressure reaches the value of saturated vapor pressure, the water molecules in the liquid phase are still continuously vaporized, and the water molecules in the vapor phase are also continuously cooled and condensed into liquid. Only because the gasification speed of water is equal to the condensation speed of water vapor, the amount of liquid is not reduced, the amount of gas is not increased, and the liquid and gas reach a dynamic equilibrium state.^[1]

In Table 1, the constants A, B and C for calculating the vapor pressure of different substances at different temperatures using Antoine formula are given as follows

lgP=A-B/(t+C)　　（1）

Where: P - vapor pressure of the substance, MmHg ；

T - temperature, ℃

Formula (1) is applicable to most compounds; For other substances that only need constant B and C values, formula (2) can be used for calculation

lgP=-52.23B/T+C 　　（2）

Where: P - vapor pressure of the substance, mm Hg;

Clausius Clapeyron equation

Where

Is the saturated vapor pressure;

by Latent heat of evaporation ；

Saturated steam Compressibility factor And saturated liquid Compressibility factor Difference.

This equation is a very important equation, and most of the vapor pressure equations are derived from the integration of this equation.

Clapeyron equation

If the above formula

Is the constant independent of temperature, the integral formula, and let the integral constant be A, then the Clapeyron equation is obtained:

Where

。

Antoine equation

Where, A, B and C are Antoine Constant, see the data table. Antoine equation is the simplest improvement of Clausius Clapeyron equation, with small error in the range of 1.333~199.98kPa.^[2]
