The perfection of a method for the determination of the temperature/vapour-pressure function of liquids by differential scanning calorimetry

Experimental determination of the (vapor + liquid) equilibrium data of binary mixtures of fatty acids by differential scanning calorimetry

“…Contreras et al [17] showed there was a relationship between the heating rate and the pinhole diameter in the avoidance of the phenomenon of pre-vaporization. In the present work, the rates of (15 and 25)°C/min were shown to be fast enough to avoid a loss of vapor through a 0.25 mm pinhole, resulting in greater stability in the (vapor + liquid) equilibrium.…”

Determination of the vapor pressure of ethyl esters by Differential Scanning Calorimetry

“…In order to determine the boiling temperature, a small hole should be made in the lid of the pan, which permits the sample to assume the same pressure as the instrument without a significant loss of material due to vaporization below the boiling temperature [9,10].…”

The effect of volatiles on the measurement of the reaction heat by differential scanning calorimetry

“…The evolution of the evaporation peaks shown in Figs.6 and 7 with the cover condition has already been reported in the literature [10,11,12] and led to propose the Standard Test Method for Determining Vapor Pressure by Thermal Analysis (ASTM E 1782-03) that entails the use of sealed crucibles with a small pinhole. With this method the boiling point can be determined from the peak onset with good accuracy (similar to ours [10]).…”
