Physical Constants of Methyl Esters of Commonly Occurring Fatty Acids Vapor Pressure

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

“…Figure 9 shows that the vapor pressure curves of these three esters were very close, which makes the separation of these compounds by distillation very difficult. Analogous behavior was found by Althouse and Triebold [11], and Singleton [12] reported that the vapor pressure of fatty acids and fatty methyl esters depended mainly on the chain length and that the number of unsaturations had little influence.…”

“…Table 3 shows the vapor pressures of the ethyl esters examined in this study in the range from 1.33 to 9.33 kPa. Althouse and Triebold [11] had problems related to the decomposition of fatty methyl esters, and verified that the methyl esters suffered decomposition above 200°C. However, in the present study, thermal degradation of the ethyl esters did not occur, since the analysis time was short (%10 min) due to the use of an intense heating rate.…”

Transpiration method: Vapor pressures and enthalpies of vaporization of some low-boiling esters

“…of vaporization from their results. That is why the original published experimental results [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27] were treated using Eqs.…”

“…At the same time the indirect [18] and the direct [20] measured vaporization enthalpies are also in a close agreement (see Table 2). The difference between [23], (᭹) [25], ( ) [18], (♦) [25], and ( ) this work.…”

Liquid–vapour equilibria of the methyl esters of alkanoic acids: vapour pressures as a function of temperature and standard thermodynamic function changes

The latter are by Stage [8]; Rose and Supina [9]; Bonhorst et al [10]; Jantzen and Witgert [11]; Rose et al [12]; Scott et al [13]; Husain et al [14]; Spizzichino [15]; Norris and Terry [16]; Althouse and Triebold [17]; and Baccanari et al [18].
