Computation of thermoacoustical and molecular properties of n-hexane, n-heptane, n-dodecane, cyclohexane and toluene at different temperatures

Abstract

From the experimental values of density and sound speed of five pure organic liquids (n-hexane, n- heptane, n-dodecane, cyclohexane and toluene), radius (r), van der Waals constants (a and b), molecular dimension (d) and nonlinearity parameters B/A were computed at five different temperatures ranging from 283.15 K to 333.15 K. Four different methods (Hartmann, Ballou rule, Johnson et al and Tong-Dong method) were used to compute to the values of B/A. The experimental data of density and sound speed were taken from the study of Romani et al. All the calculated properties were found to vary with temperature.
