ABSTRACT
This work describes the "salt effect" due to the addition of calcium chloride on the vapor pressure of 2-methyl-1-butanol. The working pressure was varied from (23.3 to 96.6) kPa and the boiling temperatures were obtained. Salt concentrations were increased from a very low value up to a concentration close to saturation. Two types of equations were applied for data correlation. The first equation was derived from the Antoine equation, and it takes to in account the presence of the dissolved salt, and the second equation was the NRTL-electrolyte model. Both models used show good agreement with the experimental data.
