ABSTRACT
Vapor pressures and liquid densities for ammonium iodide (NH4I) + ammonia (NH3) mixtures were measured over a wide range of temperatures and molalities. Vapor pressures of the NH4I + NH3 mixtures were measured at temperatures ranging from (303.12 to 373.16) K and molalities ranging up to 19.314 mol*kg-1 of NH4I. Vapor pressures were measured with a static method. The experimental values were correlated with Antoine s equation. Liquid densities of the NH4I + NH3 mixtures were measured at temperatures ranging from (303.15 to 373.15) K, pressure ranging from (10.0 to 30.0) MPa, and molalities ranging up to 16.465 mol*kg-1 of NH4I. Liquid densities were measured with a piezometer. The experimental values were correlated with a Tait form equation.
