Vapor pressures and liquid densities for ammonium bromide (NH 4Br) + ammonia (NH3) mixtures were measured over a wide range of temperatures and molalities. Vapor pressures of the NH4Br + NH3 mixtures were measured at temperatures ranging from (303.12 to 373.16) K and molalities ranging up to 18.034 mol · kg-1 of NH4Br. Vapor pressures were measured with a static method. The experimental values were correlated with Antoine's equation. Liquid densities of the NH4Br + 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 15.171 mol · kg-1 of NH 4Br. Liquid densities were measured with a piezometer. The experimental values were correlated with a Tait-form equation.
