“…Descriptions of the purification and purity measurement of these samples have been given. [7][8][9][10][11][12] Filling the samples into tubes for critical temperature measurement was in most cases accomplished in the manner described by Ambrose and Grant.4 However, for compounds with normal boiling points above 2OO0C, the vacuum manifold used had no taps, and was heated electrically in order to speed up the transfer of material into the tubes by vacuum distillation.…”

Precise measurements have been made of the critical temperatures of pure specimens of forty compounds drawn from the paraffin, olefine, cyclopentane, cyclohexane, benzene, pyridine and naphthalene series. The visual method of determining the critical point was employed, and observed critical temperatures are believed accurate to within 0.1" in most instances. The results for compounds of the paraffin, olefine and benzene series have been combined with earlier measurements on other compounds of these series to yield correlating equations, which should prove useful for predicting the critical temperatures of compounds for which experimental data do not exist. Fluorobenzene was included in the present study in order to check the accuracy of our experimental method, since a very accurate value for the critical temperature of this substance is available from P-V-T studies. The experimental value obtained by our visual method proved to be identical with the value from P-V-T studies.

“…It is b elieved that the tru e value for n-hexadecane of absolute purity would fall within these limits. Using the value 0.77370 g/cm 3 for the density at 20° C, the absolute viscosity of n-hexadecane was found to be 3.4540 centipoises (cp).…”

“…The appreciably higher purity of this material is understood to be the result of improvements in the production process . The densities of the composite sample and of the second lot of reference fuel (after treatment with silica gel) were determined at 20° and 25° C with a dilatometer (capacity about 50 cm 3 ). The densities of the NBS standard sample, and of the composite sample also, were determined at room temperature with two small dilatometers of approxi-~2~3~1~3~~~.…”

“…ratio for BCP (1.8), it exhibits a moderate gravimetric net heat of combustion (NHOC) of 42.53 MJ kg À 1 , slightly below the value required for Jet-A (> 42.8 MJ kg À 1 ), while its freezing point (À 35°C) approaches that of Jet-A (<-40°C). [61][62][63][64] To develop a selective approach for the hydrogenation of furfural to cyclopentanol, the López group investigated Cu/ MgAl catalysts. [65] Cu-based catalysts are known to facilitate polarization of the carbonyl group, which in turn allows for selective hydrogenation.…”

“…This cycloalkane has a density of 0.87 g mL −1 (12 % higher than the lower limit for Jet‐A), and excellent volumetric net heat of combustion (37.03 MJ L −1 ). Due to the relatively low H/C ratio for BCP (1.8), it exhibits a moderate gravimetric net heat of combustion (NHOC) of 42.53 MJ kg −1 , slightly below the value required for Jet‐A (>42.8 MJ kg −1 ), while its freezing point (−35 °C) approaches that of Jet‐A (<‐40 °C) [61–64] …”
