Özet

Speeds of sound and densities of 2-propanol+1-propanol, 2-propanol + 1-butanol, 2-propanol+1-octanol, and 2-propanol+1-hexanol have been measured over the entire composition range at 298.15 K. Speeds of sound of the binary mixtures have also been estimated from free length theory (FLT), collision factor theory (CFT), and Nomoto's relation (NR) and have been compared with experimental speeds of sound. The isentropic compressibilities, molar isentropic compressibilities, excess molar isentropic compressibilities, and excess speeds of sound have been calculated from experimental densities and speeds of sound. Excess molar isentropic compressibilities and excess speeds of sound of the binary mixtures were fitted to the Redlich-Kister equation. © 2005 Springer Science+Business Media, Inc.
