Solid-liquid equilibria of the seven binary systems benzaldehyde + benzene, benzaldehyde + dodecane, benzaldehyde + cyclohexane, cyclohexane + phenol, methylcyclohexane + tetrachloromethane, 2-butanone + water and acrylic acid + propionic acid have been measured by the visual method. Furthermore, the liquid-liquid equilibrium of the system benzaldehyde + dodecane was determined analytically using gas chromatography. The experimental data of the eutectic systems were compared with predicted results using the modified UNIFAC (Dortmund) method and in two cases correlated with the NRTL equation.
