Total Vapor-Pressure Measurements for Heptane Plus 1-Pentanol, Plus 2-Pentanol, Plus 3-Pentanol, Plus 2-Methyl-1-Butanol, Plus 2-Methyl-2-Butanol, Plus 3-Methyl-1-Butanol, and Plus 3-Methyl-2-Butanol at 313.15 K
Total vapor pressure measurements at 313.15 K are reported for binary systems of heptane with each of seven pentanol isomers : 1-pentanol, 2-pentanol, 3-pentanol, 2-methyl-1-butanol, 2-methyl-2-butanol, 3-methyl-1-butanol, and 3-methyl-2-butanol. The results were obtained using a Van Ness type apparatus and were fitted to the modified Margules equation using Barker’s method. The four-parameter modified Margules equation represents the data to within an average absolute deviation of approximately 0.03 kPa.
