Mutual diffusion coefficients of n-butanol + n-heptane and n-pentanol + n-heptane from 288.15 K to 318.15 K
چکیده انگلیسی
The mutual diffusion coefficients of n-butanol + n-heptane and n-pentanol + n-heptane were measured over the mass fraction of n-butanol or n-pentanol from 0.05 to 0.95 at intervals of 0.10 and the temperatures 288.15 K, 298.15 K, 308.15 K and 318.15 K at 0.101 MPa. The measurements were carried out using a digital holographic interferometry system. The expanded relative uncertainty of the mutual diffusion coefficients was estimated to be less than 2.4%. The influences of temperature and composition on the mutual diffusion coefficients were investigated. Moreover, equations for the mutual diffusion coefficients of the two binary mixtures were fitted to the data as functions of mass fraction and temperature. The correlations represent the data with the absolute average of relative deviations (AARDs) of 1.1% for n-butanol + n-heptane and 0.77% for n-pentanol + n-heptane, respectively.
