Thermophysical Properties of Liquid Squalane C_(30)H_(62) within the Temperature Range of 298.15-413.15 K at Atmospheric Pressure

摘要

The measurements results of the sound speed, density, and isobaric heat capacity of liquid squalane on the saturation line and at atmospheric pressure within the temperature range of 263.15-413.15 K are presented. The data obtained are used to calculate the ratio of the heat capacities, γ; adiabatic, β_s, and isothermal, β_T, compressibilities; thermal expansion coefficient, α_P, thermal pressure coefficient, ((partial deriv)P/(partial deriv)T)_V, and also to estimate the energy of the intermolecular interaction on the basis of the discrete-continuum model.
