The vapour pressure of solid and liquid naphthalene

Thermochemical and Theoretical Studies of Dimethylpyridine-2,6-dicarboxylate and Pyridine-2,3-, Pyridine-2,5-, and Pyridine-2,6-dicarboxylic Acids

“…20 It has been impossible to select a convenient temperature to measure the enthalpy of sublimation of pyridine-2, 3-dicarboxylic acid, since the compound decomposes upon heating, as is described in the literature. 21,22 Results Table 1 lists the results for a typical combustion experiment on each compound; ∆m(H 2 O) is the deviation of the mass of water added to the calorimeter from 3119.6 g or 2900.0 g, with the mass assigned for (calor) depending of the apparatus used, ∆U Σ is the correction to the standard state, and the remaining terms are as previously described.…”

Vapour pressures of hydroxybenzophenone UV absorbers

“…There are several strategies for the determination of vapour pressure [4] ± these range from direct measurement using a manometer [5], monitoring the gas phase concentration of the volatile species (by, for example, spectrometry [6,7]), measurement of sample volatilisation by vacuum-effusion (Knudsen cell [8,9]) or transpiration techniques [10,11] and boiling point determination under controlled pressure [12,13]. Gu Èckel and co-workers [14±17] have measured volatilisation rates of pesticides at ambient pressure by isothermal thermogravimetry.…”

The (solid+vapor) equilibrium. A view from the arc

“…An example is given by Fig. 1(a), which pertains to the static data (de Kruif et al [7]) on naphthalene. In Fig.…”

“…Data sets on equilibrium vapor pressures in ln f representation. Concave curves, class 1 data sets: (A) Ambrose et al [12]; (K) de Kruif et al [7]; (S) Sasse et al [13]. Straight lines are for class 2 data sets: (F) Fowler et al [14]; (M) Murata et al [15]; (Sa) Sato et al [16]; (G) Gildenblatt et al [17]; (MP) Macknick and Prausnitz [18]; (BC) Bradley and Cleasby [19]; (C) Colomina et al [20]; (Kr) de Kruif [21]; (E) van Ekeren et al [22].…”

“…These instruments were followed by instruments based on the dynamic method of effusion through an orifice: torsion effusion (de Kruif and van Ginkel [4]); mass-loss effusion (van Ginkel et al [5]); and the combination of torsion and mass-loss effusion (de Kruif and van Ginkel [6]). As a subsequent step a series of static instruments were developed, using diaphragm manometers (de Kruif et al [7]). And, lastly, the usability of spinning-rotor friction manometry was explored (van Ekeren et al [8]).…”
