Abstract
Total pressure measurements are reported for (n-hexane + 2-methoxyethanol) at T = (313.15 and 323.15) K, (n-heptane + 2-methoxyethanol) at T = 323.15 K, and (cyclohexane + 2-methoxyethanol) at T = (303.15, 313.15, and 323.15) K. Results were obtained by using a Van Ness type apparatus and were fitte d with the five-parameter modified Margules equation by Barker's method. Me asurements are represented to within an average absolute deviation of appro ximately 0.02 kPa. Mixtures show positive deviation from Raoult's law and s how azeotropic behaviour at the temperatures considered in this work. (C) 2 001 Academic Press.
