As discussed above,some of the problems which arise during an experimental study of the thermodynamic properties of the ROS are still poorly investigated [30] and [31].The main problems are related to complex physical–chemical phenomena in relation to the establishment of thermodynamic equilibrium in the experimental cell.During a preliminary experimental investigation of the vapor pressure,density and capillary constant for the ROS isobutane/Azmol an attempt has been made to analyze the following issues:
• How does the time taken to establish thermodynamic equilibrium depend on the concentration of the liquid solution?
• How does the time taken to establish thermodynamic equilibrium depend on the temperature in the experimental cell?
• What is the time taken to establish thermodynamic equilibrium in the thin capillaries during measurement of the capillary constant?
• What is the difference between the concentration of the surface layer of the liquid phase of ROS and the concentration of the liquid phase of the ROS?
In order to find proper answers to these questions,the dynamics of changing of the vapor pressure,density and capillary constant of the ROS after establishment of the specified temperature conditions in the experimental setup without stirring the solution in the experimental cell have been analyzed.The obtained results are depicted in Fig.2 and Fig.3.As seen from Figs.2 and 3a,the time taken to establish the equilibrium value of the vapor pressure and capillary constant for specified temperatures exceeds 5–6 h.A slight increase has been observed in the value for relative changing of the vapor pressure and capillary constant of the ROS when conducting replicate measurements during several (from 1 to 5) days.The possible explanation of this tendency lies in the time taken to establish the equilibrium concentration in the experimental cell.The values of the relative changing of the vapor pressure and the capillary constant increase as the temperature in the thermostat increases (see Figs.2a,3c).It can be explained by the rate of the diffusion processes in the liquid phase of the ROS.As follows from Fig.3b an increase of the oil concentration leads to a larger time to reach equilibrium values of the capillary constant of the ROS.The same conclusion can be made for the vapor pressure of the ROS.
