“…This is done by adjusting the opening of the needle valve of the gas cylinder or by opening the bypass line of the vacuum pump. The reliability and accuracy of the dynamic-recirculation still were verified during our previous work by measuring and comparing the saturation temperatures of heavy boiling liquids 1,2-propanediol and 1,3-propanediol with those reported in the literature . The Lutron barometer (PHB-318) was used to measure the local atmospheric pressure.…”

The saturated vapor pressure of methyl 4-tertbutylbenzoate was measured from (1.21 to 34.66) kPa in the temperature range from (398.3 to 492.4) K using a Swietoslawski-type ebulliometer. The experimental data were fitted with the Antoine and Clarke−Glew equations, which yielded Antoine parameters (A = 18.031, B = 7261.445, C = 8.857 K) and standard vaporization enthalpy (Δ l g H m θ (298.15 K) = 57.49 kJ mol −1 ), respectively. The critical properties were estimated on the basis of group contribution method. The acentric factor was calculated using these critical parameters and the saturated vapor pressures with the Antione equation. Furthermore, density, refractive indices, and viscosity of methyl 4tert-butylbenzoate were also measured in the temperature range of 293.15 to 353.15 K. Temperature-dependence correlation equations for the density (second-order polynomial equation) and viscosity (Vogel−Tamman−Fulcher) were proposed. Modified Rackett equation was used with group contribution methods to predict the density of methyl 4-tert-butylbenzoate. Group contributions and group interactions method of Nannoolal et al. were used to predict the viscosity in the temperature range of 293.15 to 353.15 K.
