Abstract: Vapor-liquid equilibria were determined for propionaldehyde-cyclohexane, propionaldehyde-methanol, and propionaldehyde-methyl ethyl ketone systems at 45.0°C use by of a modified Gillespie still. A minimum boiling azeotrope was found to occur at 691.4 mmHg and 0.915 mole fraction of aldehyde for the propionaldehyde-cyclohexane system, and a maximum boiling azeotrope at 326.4 mmHg and 0.126 mole fraction of aldehyde for the propionaldehyde-methanol system. Propionaldehyde-methanol system has a maximum or a minimum in the plot of each activity coefficient versus mole fraction. Propionaldehydemethyl ethyl ketone system is almost an ideal one.
