Vapor-liquid equilibrium at 101.3 kPa has been determined for the binary systems of 1-bromopropane with cyclohexane, heptane, and 1-butanol. The three systems exhibit positive deviations from ideal behavior. The activity coefficients and boiling point of the solution were correlated with its composition by the Redlich-Kister, Van Laar, and Wisniak-Tamir equations.
