Experiments on Vapor Pressure of KCl at Different Molar Fractions in Mixtures of KCl + K(2)SO(4)

[Image: see text] The objective of this paper is to measure the vapor pressure of potassium chloride (KCl) in its mixture with potassium sulfate (K(2)SO(4)). Evaporation behavior of pure salts of KCl, K(2)SO(4), and their mixtures at different molar fractions were examined using a simultaneous therm...

description [Image: see text] The objective of this paper is to measure the vapor pressure of potassium chloride (KCl) in its mixture with potassium sulfate (K(2)SO(4)). Evaporation behavior of pure salts of KCl, K(2)SO(4), and their mixtures at different molar fractions were examined using a simultaneous thermogravimetric analyzer (STA) at different temperatures with a pair of crucibles (outer: platinum; inner: alumina). The dependence of the vapor pressure of KCl on its molar fraction in mixtures of KCl + K(2)SO(4) was obtained on the basis of relative pressure. Results show that vapor pressure of KCl is increased to 1.2 times when a small amount of K(2)SO(4) (molar fraction from 0.05 to 0.20) is added. Evaporation of KCl will be inhibited by K(2)SO(4) when the molar fraction of K(2)SO(4) is higher than 0.27, which is its fraction in the eutectic system of KCl + K(2)SO(4). Vapor pressure of KCl decreases significantly with increasing molar fractions of K(2)SO(4) at its inhibition scope.
