Densities and Excess Molar Volumes of 2-Butanol + Cyclohexanamine plus Heptane and 2-Butanol + n-Heptane at Temperatures between (288.15 and 323.15) K

Abstract

The density p and excess molar volumes V-E for 2-butanol + cyclohexanamine + heptane and 2-butanol + heptane have been determined at temperatures of (288.15, 293 15, 298 15, 303 15, 308.15, 313.15, 318 15, and 323 15) K at a pressure of 0 1 MPa with an Anton Paar DMA 5000 vibrating tube densimeter Excess molar volumes V-E were determined and fit to the Redlich-Kister equation for the binary mixture and the Nagata-Tamura equation for the ternary mixture
