Vapor-liquid equilibria for three binary systems made of methyl ethyl ketone with acetone, methyl acetate, or N-amyl alcohol

Vapor-liquid equilibria were measured for the three binary systems made of methyl ethyl ketone with acetone, methyl acetate, or n-amyl alcohol at 100 kPa of pressure by the dew-point-bubble-point temperature apparatus previously proposed by the authors was modified in the present study. Combining the experimental dew-point and bubble-point temperature curves, vapor-liquid equilibria were obtained without using any analytical instrument
